Section 2. Functional Description

General

The AccuPulse NIBP Simulator provides accurate verification testing of blood pressure

monitors. AccuPulse is the first accurate NIBP Simulator that uses physiologically

correct waveforms for testing blood pressure monitors.

AccuPulse Plus includes these test modes:

Blood Pressure Test Mode: Selectable presets with physiologically correct Adult and

Neonate non-invasive blood pressures provide accurate verification testing of blood

pressure monitors. AccuPulse also provides the widest adult and neonatal simulation

range of any NIBP Simulator.

Leak Test Mode with High Accuracy Digital Manometer: Automatically tests the

leak rate of the blood pressure monitor, cuff and hose assembly. The user can configure

and save 3 test combinations for use where the requirements vary. This mode also

provides a high accuracy digital manometer.

Over-Pressure Test Mode: Automatically tests operation of the blood pressure

monitor’s pressure relief valve and records the set point when pressure is released by

the relief valve.

Meter Mode : In addition to the 0.1 mmHg resolution manometer, this mode offers

automated inflation to preset values or a user defined set pressure to verify static

calibration across the entire range. The units of measure for this mode can be changed

bythe user if desired.

NOTE: The unit may periodically zero itself at 1 minute intervals so that any drift is

removed. There will be a slight audible click heard when this occurs. This will happen

automatically, and only when the system is not inflated or actively testing.

Oscillometric Blood Pressure Measurement Principles

Unlike auscultatory NIBP measurement which uses a stethoscope or microphone, the

oscillometric method uses the pulses or oscillations in the cuff pressure to determine

the patient’s blood pressure. The cuff is inflated above the systolic pressure then deflated

linearly or step-wise. When the cuff pressure is high, the pulse amplitude is small; but

as the cuff pressure decreases, the pulse amplitude increases and then begins to

decrease. During deflation, the amplitude of each cuff oscillation is measured and stored

along with the cuff pressure at which the oscillation occurred. The oscillation amplitude

is then plotted against the cuff pressure to produce the “oscillation envelope” curve. The

oscillation envelope is then used to determine the patient’s blood pressure. It is widely

accepted that the mean arterial pressure (MAP) occurs at the peak of the envelope,

where the cuff oscillation amplitudes are maximum. Unfortunately, there are no

generally accepted formulas for determining the systolic and diastolic pressures. NIBP

monitor manufacturers have developed unique, proprietary algorithms for estimating

the systolic and diastolic pressures from the oscillation envelope.

Selectable CalTables™:AccuPulse’s new CalTable™ Technology makes it the first

NIBP Simulator to address the variations of algorithms between different NIBP monitors.

Selectable CalTables™ is the answer to the industry’s issue of accurate and consistent

testing of NIBP monitors with NIBP Simulators. Select the appropriate CalTable™ on

AccuPulse and then use the defined presets for accurate NIBP monitor testing.

AccuPulse can store up to 45 defined CalTables™ for accurate testing of NIBP Monitors.

These CalTables™ are approved for testing and developed by working directly with the

NIBP monitoring manufacturers to assure accurate testing. New CalTables™ are

continuously being released, please visit our web site, www.clinicaldynamics.com, for

updates.

The Generic Preset included represents no particular manufacturer's algorithm but

rather is a middle of the road approximation which will provide repeatable results as in

all prior generation NIBP simulators.

The Generic Preset can be tuned by the user for a particular need when appropriate. The

optional User Defined software module expands this capability and provides storage of

up to 45 custom presets for special applications and power users.

Power Control

Apushbutton power switch is located on the back panel of the instrument. Power is

applied to the AccuPulse Handheld device by plugging the power cord into the back of

the unit, and the power supply into an outlet. While plugged in the batteries will charge,

whether the instrument is on or off.

Device Power Up

There is a 3 second delay upon powering up before information appears on the display.

The AccuPulse Handheld initially shows a splash-screen indicating the device type, its

serial number and the version number.

Fig.S1

From this screen, the user can see the model, Serial Number and software version of the

device. After a few seconds, the splash screen is replaced by the BP Test mode screen

(NIBP Keypad), or the main menu (Generic Keypad).

When a customer later purchases an upgrade to the software or there is a software fix,

it can be installed in the field. This will be done through an update utility provided by

Clinical Dynamics as required.

Freeze the Splash Screen:

If the user needs to record key information, such as the software version they have, the

splash screen can be frozen. Immediately after the splash screen is displayed, press 2

keys simultaneously, then let go of them. This will freeze the splash screen until any new

key is pressed.

Device Modes

There are four main modes to the AccuPulse Handheld PLUS product. These are:

•BP Test: Tests the accuracy and precision of an attached blood pressure monitor.

• Supports 7 Adult and 6 Neonatal presets.

• Autosequence

• User adjustment of most parameters in BPTest mode.

• Optional CalTables provide presets adjusted to suit specific common equipment.

• Optional User-Defined module adds expanded user control of parameters for power users

•Optional Motion artifact to simulate operation of the device in harsh environments

such as inside a helicopter or ambulance.

•Optional Arrhythmia function.

• Leak Test: Tests for leaks in the BP Monitor system.

• A built-in pump supports automated Leak Test.

•Users can configure and store 3 automated settings of differing pressures and

duration.

• OverP Test: Finds the pressure at which the overpressure valve of an NIBP monitor

opens.

• A built-in pump supports automated OverP Test.

• Meter: Measure pressure in the system in tenths of mmHg

• In addition to the current reading, displays Min., Max., and a moving Average.

• Set Meter Units ( mmHg, kPa, cmH20, psi ).

• The built-in pump supports automated inflation in steps of 50mmHg.

• The built-in pump supports automated inflation to user defined set point (adjustable

on the fly).

When selecting another mode, results displayed on various screens are maintained so

that a user may run a test in one mode, and come back to a previous mode to see the

last data collected in that mode.

NOTE: The unit may automatically zero itself at 1 minute intervals so that any drift is

removed. There will be a slight audible click heard when this occurs.

Front Panel Buttons

There is a variation in front panel labels between single function NIBP units and future

variations with multiple parameters. Dedicated mode buttons were used originally,while

newer releases support further expansion through the use of a generic set of keys. The

overall operation of the unit is consistent between versions except that in the newest

version the mode buttons have become menu selections on the screen.

Mode Buttons

(units with only NIBP)

Pressing any of the front-panel mode buttons <BP Test> , <Leak Test> , <OverP

Test> or <Meter> causes the AccuPulse Handheld to change to the indicated mode.

The exceptions are when there is pressure in the system above a given threshold. Each

mode has a trigger pressure past which the user cannot leave the mode. For instance,

when in BP Test Mode, the AccuPulse Handheld will generate pulses automatically when

Press > 10mmHg. The AccuPulse Handheld will not change modes until the pressure

in the system is < 10mmHg for that reason.

Menu Selection Buttons

(Generic Keypad)

The front-panel buttons <Scroll Up> and <Scroll Down> move the highlight up

and down the menu list, <ENTER> selects the currently highlighted selection.

Pressing <ESCAPE> will back out of the current menu or mode, moving up the menu

tree to the next level. The exceptions are when there is pressure in the system above a

given threshold. Each mode has a trigger pressure past which the user cannot leave the

mode. For instance, when in BP Test Mode, the AccuPulse Handheld will generate pulses

automatically when Press > 10mmHg. The AccuPulse Handheld will not change modes

until the pressure in the system is < 10mmHg for that reason.

2. Assuming you are using an adult cuff, wrap the cuff around the AccuPulse case just

as you would wrap it around a patient’s arm. You should be able to fit a pencil between

cuff and mandrel. Please see “Wrapping the Cuff Around the Cuff Support” illustration

below:

3. Connect the longest section of the adapter “T”

hose to the pressure port on the rear panel of the

AccuPulse.

4. Disconnect the cuff from the blood pressure

monitor hose. (As if you were going to replace the

cuff.) In the case of a dual-lumen hose, only one of

the hoses will be connected to the adapter.

5. Connect the cuff to one short side of the adapter

hose “T” and the hose to the other side of the “T”.

Ensure that an airtight seal is achieved on all three

couplings. Please refer to “Connecting AccuPulse to

the NIBP Monitor” illustration below:

Here the AccuPulse acts as a pressure meter (manometer) with 0.1mmHg resolution. In

addition to the current value, min, max and a moving average are also simultaneously

displayed.

The user has the option to use the internal pump to inflate the system to various

pressures.

Using the Cal button increases the pressure in 50mmHg steps providing an easy way to

do a multi-point calibration check.

Using SetP allows the user to select any value for an inflation point from 50-400 mmHg

and adjust it up and down in steps as small as 1 mmHg by using the UP/DOWN arrow

keys.

Leak Test Mode

Press the Leak Test button (NIBP keypad), or for the (Generic Keypad) use the Escape

button, to return to the menu and select Leak Test.

The default is an automated test. When Start is pressed the AccuPulse Plus pump will

inflate to a preset pressure, settle at that point, then begin counting down the preset

time. At the end of this the difference between the start and end pressure is displayed.

Over-P Mode

Press the OverP Test button (NIBP keypad), or for (Generic Keypad) use the Escape

button, to return to the menu and select OverP Test.

When Start is pressed the AccuPulse Plus pump will inflate and the AccuPulse Plus

graphs the pressure. When the overpressure valve releases, the AccuPulse reports the

maximum pressure achieved.

Section 5. Detailed Operation

1) BP Test Mode

The Simulation Engine operates in this mode, delivering pressure pulses to the cuff. The

servo action begins when pressure in the system is > 10mmHg. If the user leaves the

menu tabs displayed, the servo will still start up if the system pressure becomes >

10mmHg. When it starts, the software will change the screen to display the test being

performed.

The figure below shows a typical BP Test Mode Screen with a maximum pressure scale

of 200mmHg (left edge of screen).

The pressure is at 0 mmHg ( upper right corner of screen ).

Approximately 27 seconds of pressure data is displayed on screen at one time ( bottom

scale is seconds ).

The top line of text indicates the current test settings in the format:

A(dult) patient, 120/80(93) SYS/DIA(MAP) pressure, 80 Beats Per Minute pulse, and

100% nominal amplitude.

At the bottom is an indication of the envelope set being used. The default Generic Presets

are used in this example.

Three parameters may be adjusted directly in this mode:

•The Up/Down arrow buttons cause the pressure scale to shift between 100, 200 and

300 mmHg max.

•The Left/Right arrow buttons cause the pressure data to be scrolled 10 seconds at a

time from 0 seconds to 120 seconds if the test time exceeds one screen of time. The

Left/Right arrow buttons are only available for test review, they do not scroll while the

test is active.

•Motion Artifact: This is a purchased option upgrade. Toggle motion artifact

off and on by pressing F1.

(The Motion Artifact option is covered in detail later in the manual)

The base AccuPulse Plus has supporting adjustment tabs accessible from this mode.

The support tabs are accessed by pressing the <Menu> button. These tabs

allow the user to make adjustments for this mode, selecting Adult or Neonatal patient

types, different Systolic / Diastolic presets, and Pulse Rate. Support tabs also provide the

more advanced ability to tune the presets if needed by shifting them up or down,

adjusting the overall amplitude of the pulses, and within the default generic envelope

adjusting the output for a better match to your monitor.

Fig. BP1

The Generic Trim tab is not available when you have selected one of the optional

CalTables for use. These are already optimized for specific equipment by Clinical

Dynamics. CalTables are a purchased option upgrade.The CalTables option is

covered in detail later in the manual.

The Generic Trim tab is not available when you are working with the optional User

Defined module. This option has the same function individually available for each of its

45 settings. User Defined Mode is a purchased option upgrade. The User

Defined Module option is covered in detail later in the manual.

Support Tabs for BPTest Parameter Adjustments

NOTE: Several last used settings are retained across power cycles and become the startup

default. Some others will be reset when you exit the current testing session or mode.

They are identified as appropriate in each parameter adjustment below.

To open the Support Tabs, from the BP Test Screen, press <Menu>

The Left/Right arrow keys are used to select the desired tab for the parameter to be

adjusted.

The graphic right arrow ‘>’ next to “Shift” in figure BP-2 indicates there is another Tab

past the end of the screen. The fifth tab which is just off screen in this case is the Amp

tab. When the user has selected a tab to the right, past the Shift tab, there are now tabs

off screen to the left, so the first tab has a leftarrow ‘<’, indicating this situation. (See

the “Amp Adjust Tab” section for a screen shot of this situation).

BP Adjust Tab

BP presets are presented in 2 ranges occupying 2 tabs; BP-1 and BP-2

The BP-1 tab contains the Adult / Neo(natal) selection control. When switching between

Adult and Neo mode, the last used preset for each mode is recalled as the initial current

selection. This memory of the BP preset last used is also retained across power cycles.

Pressing F-Key below the <Neo/Adult> icon of Figure BP-2 causes the mode to be

toggled between Neonatal and Adult Modes. Pressing the remaining three F-Keys chooses

one of three BP Presets for this patient type. Figure BP-2 shows the first BPTest tab.

Because there are more than 3 presets, there is a second BP tab.

Figure BP-3 shows the second BPTest tab. The remaining presets may be selected using

the second BPTest tab by pressing keys <F1> through <F4>.

PR Adjust Tab

Figure PR shows the Pulse Rate adjust tab for the BP Test Screen.

From this screen, the user adjusts the simulated pulse rate. Pressing F1-F3 selects the

associated Preset Rate.

The user may also select any rate from 15-330 BPM.

Using the Up/Down arrow keys, the bpm is adjusted by the value indicated by the Step

label above F-4.

Pressing F-4 (STEP:) changes the step size from 1 to 5 to 10 to 50, and back to 1.

The adjusted Pulse Rate value will be retained and used for all presets used in this testing

session.

This means the user can easily run a range of tests at their own desired Pulse Rate while

working in the same patient mode (Adult or Neo). This is true for both manual

selections and Auto Sequences.

The PR setting change will not be retained when switching between Adult and Neo mode.

This change will also not be retained across a power cycle.

Shift Adjust Tab

Figure S shows the pressure Shift tab for the BP Test Screen.

This function allows the user to slide the factory preset up or down by x mmHg.

Example: Starting with the 120/80(93) preset, apply a shift of -5 mmHg.

The preset will now run as 115/75(88).

The display will show the 'new' shifted value that is actually being used.

Shiftis limited to an absolute maximum of +/- 100 mmHg but has additional limits

imposed by the range of the instrument. It is strongly recommended to start with the

nearest preset to what you want and shift that by some reasonable amount, rather than

try to shift a preset by some large amount.

The Shift tab control operates the same way as the PR adjust tab.

Pressing F1-F3 selects the associated fast select shift value of +/- 10 mmHg, or zero

which returns to the original preset value.

Fig S.

BPTest Mode Cont’d

Using the Up/Down arrow keys, the shift is adjusted by the value indicated by the Step

label above F-4.

Pressing F-4 (STEP:) changes the step size from 1 to 5 to 10 to 50, and back to 1.

The Shift value will be retained and used for all presets used in this testing session.

This means the user can easily run a range of tests with the factory presets offset to the

users preference or need while working in the same patient mode (Adult or Neo). This

is true for both manual selections and Auto Sequences.

The shift setting change will not be retained when switching between Adult and Neo

mode. This change will also not be retained across a power cycle.

Amp Adjust Tab

Figure A shows Amplitude adjust tab for the BP Test Screen.

Amplitude adjustment is an advanced feature and generally should not be needed for

most applications. The default value of 100% is appropriate for normal Adult and Neo

cuff sizes. This adjustment might be needed when using cuffs that are significantly larger

or smaller. Typically this may be needed by manufacturers and researchers. This

function allows the user to increase or decrease the overall amplitude of the 'pulse

signal'. The scale is a percentage of the nominal default value of 100%.

The Amplitude tab control operates the same way as the PR and Shiftadjust tabs.

Pressing F1-F3 selects the associated fast select relative amplitude value of 25%, 50%, or

100% which returns to the original default value.

Using the Up/Down arrow keys, the amplitude is adjusted by the value indicated by the

Step label above F-4.

Pressing F-4 (STEP:) changes the step size from 1 to 5 to 10 to 50, and back to 1.

The Amplitude adjustment range is from 0% to 150% of nominal.

The amplitude value will be retained and used for all presets used in this testing session.

This means the user can easily run a range of tests with the factory presets offset to the

users preference or need while working in the same patient mode (Adult or Neo). This

is true for both manual selections and Auto Sequences.

The Amp setting change will not be retained when switching between Adult and Neo

mode. This change will also not be retained across a power cycle.

Trim Tab

(only available with the Default Generic CalTable setting selected )

Figure T shows the Trim tab for the BP Test Screen.

This is an advanced feature and it's use may not be appropriate for many users. In

particular, there should be consideration of the implications if the simulator is shared

amongst multiple users, or if a variety of equipment from different manufacturers needs

to be tested with the same AccuPulse Plus unit.

This Trim function is provided for customers who want to dial in the AccuPulse for use

with specific equipment. The baseline generic oscillometric envelope is not based on any

one monitor. It is normally expected that test results may not match the preset value.

Trim allows the user to adjust the envelope for better matching of the results. The

adjustment is permanently saved until changed again by the user.

To use this feature take several readings with the NIBP monitor of interest, noting the

typical results. It is recommended to check several known good units to develop a

reasonable average of the typical bias.

(example with 120/80 preset the result averages 124/78 which is +4 SYS and – 2 DIA)

Next make Trim adjustments to compensate for these differences

(example Trim is Delta SYS -4, Delta DIA + 2)

NOTE: Trim adjustments do not change the displayed value (labels) of the setting. They

are intended to allow users to develop settings that give results matching the simulator

displayed values.

Pressing F1 (delta Sys) or F3 (delta Dia) selects the parameter to be trimmed.

Using the Up/Down arrow keys will change the selected parameter trim value in steps of

1mmHg.

Pressing F4 (Save) stores and applies the change.

The maximum adjustment range is +/- 25 mmHg but will be further restricted as

adjusted values near the MAP value or the end range of the simulator.

The adjusted Trim value will be retained and used for all future tests with the Generic

CalTable. It will not reset itself, even with a power cycle. Trim values can only be cleared

by deliberate action of the user.

The optional User Defined module has similar functionality but allows for 45 settings

and adds the ability to independently select Systolic and Diastolic values. User Defined

Mode is a purchased option upgrade. The User Defined Module option is covered

in detail later in the manual.

Mode and Option Tabs for BPTest

These tabs allow the user to make selections and adjustments for Auto-Sequence and

the optional upgrades. The exact combination of tabs you will see here is dependent

upon which software options you have purchased.

NOTE: Several last used settings are retained across power cycles and become the

startup default. Some others will be reset when you exit the current testing session or

mode. They are identified as appropriate in each subsection below.

Shift Adjust tab Cont’d

Fig. A.

Fig. T.

Toopen the Mode and Option Tabs, from the BP Test Screen,

press the <BPTest> button (NIBP Keypad), or, the Enter button (Generic Keypad)

The Left/Right arrow keys are used to select the desired tab for the parameter to be adjusted.

The graphic right arrow ‘>’ on the last tab to the right, indicates there is another tab past the

end of the screen. When the user has selected a tab to the right, there may now be tabs off

screen to the left, so the first tab has a left arrow ‘<’, indicating this situation.

Seq Tab (Auto Sequence)

Auto-sequence is included in all units to run a full sweep of the BP Test presets. After

the selected number of tests at one BP Preset is complete, the AccuPulse will decrement

tothe next BP Preset to continue testing.

F2 On/Off enables or disables the autosequence function. It will be Off by default upon

power up.

F3 Next Param selects one of the 3 sequence parameters for adjustment.

F4 Inc Field will increase the value of the selected parameter.

The parameter choices are;

AutoSeq: Rpt 1-10 (times to run each preset before advancing)

Run Once - After the final BP Preset has run, AccuPulse will stop advancing through the

presets. It ends by returning to the first preset and switching the autosequence state to

off.

Run Cont. - After the final BP Preset has run, AccuPulse will return to the start and

repeat the sequence in a continuous loop.

Timeout: 0-9 seconds Use of this Timeout can help prevent AccuPulse from

advancing on monitor retries. This causes AccuPulse to insert a delay at the end of each

NIBP cycle before it assumes the monitor has obtained a reading. Some monitors may

at times deflate completely without obtaining a valid result and then reinflate after a few

seconds. The time between good results is typically longer than that of a retry.

The sequence settings will be used in this testing session. The settings are not retained

across a power cycle.

NOTE: The User Defined option module also adds an Auto-sequence variation of its own, in which

the user can select their own defined presets to run. Further detail is provided in the User Defined

Module section of the manual. User Defined Mode is a purchased option upgrade.

Cal Tab (CalTable selection)

This is an optional software upgrade

Figure CT1 shows the CalTable selection tab for the BP Test Screen.

The one Generic CalTable is standard issue for all units. The CalTables option is in

addition to that.

Ifyou have purchased the CalTables software option you can select a set of presets that

have already been tuned by Clinical Dynamics to match the indicated Make / Model of

equipment. This saves the user from always having to determine what the normal

expected results should be for a given NIBP instrument. With an appropriate CalTable

selected, the result typically agrees with the preset within just a few mmHg.

While in the BP Preset Mode, select the Cal tab.

The Up/Down arrow keys walk through the 45 possible selections.

Press F4 (Select CalTable) to apply the current selection for use.

Space for 45 selections is currently available but not all are used. They allow for adding

new CalTables to the system over time. Unpopulated spaces are labeled as invalid and

can not be selected for use.

The selected CalTable will be permanently stored as the default and used until the user

changes it again. This setting will be retained across a power cycle.

Mode Tab (BP User-Defined Mode)

This is an optional software upgrade

Figure UD1 shows the BP User-Def selection tab for the BP Test Screen.

The BP Preset mode is standard issue for all units and the CalTables option runs under

that mode. Purchase of the User-Defined Mode adds this special mode selection to the

menu system. Settings made here remain independent of the BP Preset mode.

If you have purchased the User-Defined software option you can edit, store and run up

to 45 presets of your own design. The user chooses independently the value of each

parameter which means you can test and explore behavior under a very wide range of

test conditions such as at differing pulse pressures. These settings can be trimmed to

match the unit under test as well. All settings here are stored permanently and will not

be cleared. The user can, of course, always go back and change them when they choose.

From the BPTest screen, press BPTest (or Enter) to reach the Mode tab.

Press F2 to select BP User-Def Mode. Press BPTest (or Enter) again to return to the BPTest

screen.

Figure UD2 shows the User-Def menu for the BP Test Screen.

From BPTest screen press Menu to access the controls for User Defined mode

Figure UD3 shows the User-Def Edit menu for the BP Test Screen.

From the User-Def menu, pressing F3 (Edit) opens the current selection for editing and

brings up the User-Def Edit Menu.

F1 (Select) moves the highlight to select a parameter for editing.

Left/Right arrow keys also move the highlight to select a parameter for editing.

The Up/Down arrow keys change the value of the highlighted parameter.

F2 (Trim) opens the Trim Menu.

F4 (Enter) saves the changes.

Figure UD4 shows the User-Def Trim menu for the BP Test Screen.

From the User-Def Edit menu, pressing F2 (Trim) opens this additional menu level of

editing.

F1 (Select) chooses Delta Sys, Delta Dia, or the MAP label for editing.

Left/Right arrow keys also move the selection highlight.

The Up/Down arrow keys change the value of the highlighted parameter.

F2 (Trim) returns to the standard Edit Menu.

F4 (Enter) saves the changes.

User-Defined Mode Ranges and Use

This is part of an optional software upgrade

The User Defined parameters can be adjusted over a very broad range. For some

parameters the range well exceeds that of typical NIBP monitors currently available. This

extended range is provided for research and to explore the true absolute limits of an

instrument. We impose few limits on the combinations available and leave it to the user

to decide what is valid for their purpose or physiologically unrealistic.

General range limits:

Systolic range is 20 – 295 mmHg

Diastolic range is 10 – 260 mmHg

Pulse Rate range is 15 – 330 BPM

Amplitude range is 0 – 150 % of our nominal Adult setting

A/N (Adult/Neo) is a label only. The appropriate amplitude for neonatal use must be set

by adjusting the amplitude setting.

The actual value of MAP output is set internally by the rule of thirds and follows changes

of the SYS/DIA settings made by the user. By default this value label is not displayed. It

can be turned on using the Trim menu. The MAP value displayed is a label only. In the

Trim Menu a user can adjust the value displayed to match the expected monitor results,

but can not directly move the underlying MAP point.

When making adjustments a minimum pulse pressure (Sys – Dia) of 10 is enforced.

Attempting to move the systolic value below this spread will push the diastolic down as

well. Raising diastolic operates in similar fashion.

The maximum Trim value range is +/- 25 mmHg for both Delta Sys and Delta Dia. This

range is limited as needed when the Trim would otherwise meet the MAP point or the

end range of the AccuPulse Plus unit.

All User Defined settings will be permanently stored until a user changes them. These

will be retained across a power cycle.

Seq Tab (Auto Sequence) User-Defined mode feature extension

The User Defined option module also adds some extended functionality to Auto-

sequence while operating in the User-Def Mode. These changes allow the user to choose

any of the 45 User-Def points to define their own sequence.

Under the Seq Tab pressing F1 (Seq Config) opens a new screen and menu to select the

points to use.

F1 (Add) allows the user to add points to the sequence immediately following the current

highlight point.

Up/Down arrow keys change the value of the highlighted sequence location.

Left/Right arrow keys move the highlight across the sequence list.

F2 (Del) will delete the currently highlighted point from the sequence.

F3 (Save) stores the currently displayed sequence for use.

F4 (Exit) leaves without saving any changes.

Note that points to run do not have to be adjacent in the User-Defined Mode list, nor in

any particular order, and a single point can be used more than once. (Example: 1, 18,

43, 44, 7, 32, 18, 32 )

All other Autosequence functions remain unchanged from the standard operation.

Mot Tab (Motion Artifact)

This is an optional software upgrade

The Motion Artifact option provides a way to mix noise into the normal pulse patterns.

While in BP Test mode F1 switches Motion On and Off.

Fig. UD3.

Fig. UD4.

User Defined Auto Sequence Sequence Configuration

Figure M1 shows the Motion Tab screen.

Fig. M1

F2 selects Frequency parameter for adjustment.

F3selects Amplitude parameter for adjustment.

Up / Down arrow keys adjust the value of the highlighted parameter.

Amplitude range is 1-8

Sinewave Motion Frequency range is 1-25 Hz

Toggle motion artifact on and off while in BPTest Mode by pressing F1. Figure M2 shows

the resulting “M” in the upper-right corner of the screen, followed by 5Hz, indicating the

motion artifact frequency. Also, there is an 8 to the right of the 5Hz indicating the motion

is of amplitude 8

These Motion settings are retained (and used when turned on by F1) for testing any

patient type,in any BPTest mode, until power is cycled.

ArrythTab (Arrhythmia)

This is an optional software upgrade

The Arrhythmia option provides variable missed pulses during simulation.

F1 (Delay) selects Delay parameter for adjustment.

F2 selects Frequency parameter for adjustment.

Up / Down arrow keys adjust the value of the highlighted parameter.

F4 turns the arrhythmia on or off.

Delay range is 2.0 – 8.0 seconds, in steps of 0.5 seconds

Frequency range is 1 - 19 pulses out of 20 that the Delay setting will be applied to.

Example: A normal simulation at 60 BPM delivers pulses at 1 second intervals.

With Asystole set to 5.5 seconds and Frequency set to 3/20 :

There will be a 5.5 second delay added to the time between the first three pulses out of

20.

After 20 pulses total the pattern will repeat.

These Arrhythmia settings are retained for testing any patient type,in any BPTest mode,

until power is cycled.

Leak Test Mode

The Leak Test Mode allows the user to evaluate the system under test for leaks and to

help determine the source of any leaks. If this rate exceeds the manufacturers’

specifications, performing the test again while isolating portions of the pneumatic circuit

will guide the user to the leaking component.

While this test is running, you can also check the Static Calibration of your NIBP

monitor. Compare the AccuPulse manometer in the upper right corner to the pressure

on the NIBP monitor.

F1(Zero) will zero the AccuPulse.

F2(Reset) will reset the Leak Test. NOTE: Results remain displayed until a new test is

started.

F3 (Start) start the Leak Test.

F4 (Auto) / F4 (Manual) toggles between automatic using the internal pump, or manual

mode using the inflation bulb.

The button label states the current mode, Auto is the default.

The Menu key opens the Leak Test Configuration screen where 3 user presets can be

stored.

Note: There should always be a pressure volume in-line with the AccuPulse

and the device under test. Either a pressure chamber (such as Clinical

Dynamics’ 250ml pressure chamber) or an NIBP cuff should be used to

perform this test. Consult the monitor service manual as the manufacturer

may specify a certain fixed volume to use. Changing volumes changes the

meaning of the test.

Because the total leak rate in (moles of air / minute) cannot be directly

measured by this instrument, reasonable efforts should be made to

standardize the total volume of air used in the test. Then, a leak rate of x

mmHg / minute translates into a real leak rate, calculable in moles /

minute. If the cuff hose is used without a pressure chamber,the same

number of moles leak rate (with a chamber) per minute is proportional to

aleak rate scaled by :

(Volume Chamber + Volume Hose) / VolumeHose.

This can give leak rates of 50-100 times the leak rate with a chamber.

Furthermore, the automated mode pressure inflation algorithm will not

work with arbitrarily small volumes. If the leak rate is desired at a higher

precision start value, it may need to be performed manually when using a

small volume. Even here, the technician is cautioned to use the SAME

volume every time; changing from an 8 foot to a 10 foot hose could change

the test results by nearly 20 percent.

If testing leak with a cuff, the time to settle at the initial (start) pressure

may be over a minute. A fixed volume chamber will provide much faster

settling.

In Auto mode there is a valve open initially and while the test is idle so that pressure

equalizes to zero.

Place the monitor in the calibration or service mode. (See your NIBP Monitors Service

Manual for instructions on how to enter calibration or service mode.) Please check all

connections.

Press the <Start> key. The valve closes and the pump will run. During this time the

screen will indicate “Inflation In Progress”.

After the pressure stabilizes at the target test value, the test will begin automatically. The

screen indicator changes to “Test In Progress”. The starting pressure is captured and the

timer begins counting.

At the end of the preset time (60 seconds default) the screen indicates “Test Complete”.

The final difference from the start pressure is locked in as the Leak Rate. The valve does

not automatically open, so the user can continue troubleshooting if more time is needed

by observing the manometer value. The user can release the pressure by pressing reset

once without losing the results.

Manual Leak Test

In Manual mode the title bar does not indicate a target start pressure.

The valve is closed immediately so that the user has total control of the pressure in the

system.

In manual mode pressure in the system must be greater than 10mmHg for <Start> to

trigger a timed measurement. The timer runs for the preset time indicated in the title

bar and the result is locked in at the end. The internal valve does not open, the user

must release the system pressure.

Pressing Reset while running a manual test will stop the timer and clear the current

result. If pressure is not released from the system, pressing <Start> will begin a new

test starting at the current system pressure.

Leak Test Configuration Menu

Three user configured test sets are permanently stored for reduced setup time on

repeated operations.

This provides the user with flexibility to choose the test conditions that suit their needs.

F1-F3 (Set1 through Set3) select the settings to use or configure.

Left / Right arrow keys select the parameter to adjust.

Up / Down arrow keys adjust the value of the highlighted parameter.

Target Pressure range is 50 – 300 mmHg

Test Time range is 20 – 120 seconds

Changes are saved immediately.

In manual mode the time of the current set will be used.

Target pressure has no meaning in manual mode.

OverP Test (Over Pressure)

This mode is used to verify operation of, and determine the pressure at which, a

monitor's over pressure safety functions. For this test, the system is inflated and the

AccuPulse Plus graphs the pressure. When the overpressure valve releases, the

AccuPulse reports the maximum pressure achieved to the user on the screen in a pop

up window.

Both manual and automatic modes are provided. Some NIBP monitors have auto-inflate

to self-test their Over Pressure protection, manual mode may be used when this is the

case. In auto mode the AccuPulse internal pump will provide the system inflation.

F1 (Toggle) will toggle display of the final result window, allowing the user to review the

plot.

F2 (Reset) will reset the Leak Test and clear any results.

F3 (Start) start the automatic Leak Test.

F4 (Auto) / F4 (Manual) toggles between automatic using the internal pump, or manual

mode using the inflation bulb.

The button label states the current mode, Auto is the default.

The Up/Down arrow buttons cause the pressure scale to shift between 200, 350 and 450

mmHg max.

If the system pressure should exceed 400mmHg the AccuPulse unit will release the

pressure to protect itself and any attached equipment. This status will be indicated as

“> 400mmHg”

If the test time exceeds 120 seconds the status will be indicated as “Time Out” and no

result will appear.

The pump offers smooth steady inflation and less bounce in pressure than the hand-

inflation bulb does. Pressing start closes the AccuPulse dump valve and starts inflation.

Atest status indication appears at the top of the screen. When finished the status

indicator shows “Complete” and a peak value is displayed.

The normal result screen is shown here on the left.

On the right is after pressing <Toggle> button to turn off the peak display. Toggle again

will return it.

Manual Over Pressure

Manual mode operates the same as Auto except it is up to the user with an inflation bulb,

or an NIBP monitor's own inflate pump, to provide the pressure. Manual leak test starts

as soon as the user pumps the pressure to greater than 10mmHg.

Figure OP4 shows the manual state for the OverP Test Mode screen.

In manual mode the user and monitor directly control inflation and release of pressure.

The AccuPulse dump valve only opens if pressure reaches > 400 mmHg.

Meter Mode

This mode provides the user a 0.1mmHg resolution manometer in the upper right

corner of the display. Also Min, Max and a moving average of the pressure are presented.

The Cal and SetP functions provide convenient methods of checking accuracy at specific

pressure points.

The user may also change the units of measurement (for this mode only) so the

AccuPulse can be used to verify pressure readings in other applications where mmHg is

not the standard unit of measure.

During the first 10 minutes after power-up, the pressure zero drift may be significant for

the most precise readings.

Allowing time for the instrument to stabilize is strongly recommended.

F1(Zero) will zero the manometer

F2 (Reset) will reset the Max, Min, and Avg.

F3 (Cal) Enters the Calibration check mode. This provides incrementing steps of 50

mmHg.

F4 (SetP) Enters the Set Pressure mode where the user can interactively set a target

inflation value.

The user may Zero the pressure sensor with the unit open to the atmosphere to remove

any drift. The unit also automatically Zeroes every minute when pressure in the system

is below 10mmHg. A valve vents pressure to the atmosphere so that any pressure in the

system is released before the zeroing takes place.

Similar to a voltmeter, Max. and Min fields track the maximum and minimum the

pressure achieves in the system. Avg. is a moving average of the last 8 samples at 1/4

second intervals, for a 2 second total average.

Meter Mode Static Calibration Function

This mode uses the AccuPulse internal pump and its control routine to incrementally

check a full range of pressure values. This function will increase the pressure in steps of

50 mmHg. This function gives the user a fast and easy alternative to the Set Pressure

function which offers more control if needed.

When working with this function, several key labels are context sensitive and will be

changed, hidden or presented according to the present state of the test.

F1 (Reset) Resets only the Min, Max, and Avg. values.

F2 (Enable)/ F2 (Disable) Turns on or off the tracking to maintain pressure at the target

point.

F3 (Start) / F3 (Next) Start the calibration check at zero. / Inflate by another 50 mmHg

to the next point.

F4 (Quit) Exit the test, releasing the pressure and returning to the starting point.

On the AccuPulse press Start to begin the static calibration check.

After verification of zero, press Next which will inflate the system to 50 mmHg.

When the target pressure is reached Accupulse will try to maintain the pressure at this

value. The corrections made by AccuPulse may cause a slight change just when you don't

want it. Pressing Disable will turn off adjustments allowing the pressure to naturally

settle and drift down smoothly. If the pressure should drop too low, pressing Enable will

bring it back to the target value again.

Next will always increment to the next point, even if Disable is currently in use.

Pressing Quit will always abandon the test from the current point, deflate the system and

return to the beginning.

To exit this function and return to the Meter screen, press either Meter (fixed keypad),

Escape or Enter (Generic Keypad).

Meter Mode Set Pressure Function

This mode uses the AccuPulse internal pump and its control routine to inflate and

maintain a user selected pressure value. This function gives the user control to choose

values in steps of 1 mmHg rather than the fixed steps of 50 provided by the static

calibration function.

When working with this function, several key labels are context sensitive and will be

changed, hidden or presented according to the present state of the test.

F1 (Reset) Resets only the Min, Max, and Avg. values.

F3 (Start) / F3 (Enable)/ F3 (Disable)

Start the calibration check at zero. / Turns on or off the tracking to maintain pressure

at the target point.

F4 (Quit) Exit the test, releasing the pressure and returning to the starting point.

Up / Down Arrow Keys adjust the target pressure over the range of 50 – 400 mmHg

Set the monitor to be tested to the appropriate service / calibration mode per its

documentation.

On the AccuPulse use the Up / Down arrow keys to set the target pressure.

(Target pressure setting adjustments can also be made while the test is active.)

Press Start to begin the test.

When the target pressure is reached Accupulse will try to maintain the pressure at this value.

The corrections made by AccuPulse may cause a slight change just when you don't want it.

Pressing Disable will turn off adjustments allowing the pressure to naturally settle and drift

down smoothly. If the pressure should drop too low, pressing Enable will bring it back to the

target value again.

Pressing Quit will always abandon the test from the current point, deflate the system and

return to the beginning.

To exit this function and return to the Meter screen, press either Meter (fixed keypad), Escape

or Enter (Generic Keypad).

Meter Mode Units

In the NIBP world, mmHg is the standard unit of measurement. However, the AccuPulse

device may be used as a +/- 1mmHg pressure meter in the preferred units for the given

situation. This offers flexibility to use this instrument as a general purpose pressure

meter to verify pressure readings of other equipment.

NOTE: This unit of measure change only affects Meter mode.

F4 (Change Units) pressing this rotates through the possible selections.

The change is immediate and can be seen on the manometer in the upper right corner

of the screen.

The units supported at this time are:

•mmHg

• kPa

•cmH20

•psi

This setting will be permanently stored until a user changes it again. This will be retained

across a power cycle.

Device Configuration

In units with an NIBP specific keypad, the configuration settings are presented on the

Meter menu tabs. In units with the multi parameter generic keypad, the device

configuration has been moved to be a top level menu item.

Aside from the location, the device configurations generally operate the same way and

will be presented here together. These settings will be permanently stored and used as

defaults until a user changes them again. They will be retained across a power cycle.

The two versions of the Device Configuration screens are shown here:

Power Configuration

This sets inactivity self turn off and other power saving options. The speaker may also be

disabled here.

Regardless of any settings made here, the unit will always shutdown in 10 minutes when

the Low Battery alert is flashing. Connecting the AC/DC charge adapter during this time

will prevent shutdown.

F1 (Toggle Sound) Turns the speaker Off/On.

F2 (Disp LED) toggles the display LED back light between always on, and inactivity timer

F3 (Idle Timer) toggles the unit idle shutdown timer On/Off

Idle Timer Shutdown will enable the unit to shut itself off after 30 minutes of inactivity.

By default this timer is turned off.

The display LED timer will turn off the backlight LED after 10 minutes of inactivity.

Pressing any key will reset the timer and turn the light back on. By default this timer is

turned off.

Both timers are reset with any button press.

Battery / Charger Voltage Status

This will indicate the current power source in use, Battery or Charger, and its voltage.

When the Batteryvoltage falls to 13.95V a Low Battery warning will flash on everyscreen.

Once it starts flashing the unit will shutdown in 10 minutes, allowing enough time for

the user to complete the current task or plug in the external power charger.

The low battery alert is a blinking reverse-video bar that is drawn on the screen.

To fully charge the internal battery takes about 3.5 hours.

The nominal battery voltage displayed at full charge is approximately 16.5v

Low Battery alert will come on when the battery drops to 13.95V.

Shutoff will occur 10 minutes after the Low Battery alert begins.

Beyond the timeout, a hardware limit will force the unit off when battery is below 11V.

The battery voltage discharge curve is relatively slow and smooth until it approaches the

end of its useful charge. Then the voltage will fall rapidly.

The Battery is a LiOn pack and an intelligent charge circuit is used. The battery will be

charged as needed and as fast as possible within safety bounds. It will charge anytime

the charge adapter is being used, whether the simulator is turned on or not. While the

simulator is in use charging may be slightly slower causing some increase in the time

needed to fully recharge the battery.

Section 7. Remote Control

Overview:

This remote control tries to adhere as closely as possible to the remote control spec of

the legacy SmartArm and AccuPulse remote control commands. That is, typically,

commands and command feedback are accompanied by similar syntax.

This section explains the commands in detail. A less detailed short form listing of the

most commonly used commands is presented at the end which can be used for fast

reference.

Set up / protocol – Before developing a software communications driver for use

in your AccuPulse application, it is

recommended that the developers familiarize themselves with the communications

protocol using a dumb terminal or a PC operating as a dumb terminal.

NOTE: Windows VISTA and Windows 7 do not include a terminal program. Free / Open

Source terminal applications such as TerraTerm can be easily downloaded. Another

solution is to copy Hypertrm.exe and Hypertrm.dll from Windows XP (no install is

required, just keep them in the same folder).

Baud Rate: 921600 bps

Data Bits: 8

Stop Bits: 1

Parity: None

ANSI emulation

No Flow Control

Local Echo and CR-> CR/LF are helpful when entering commands by hand.

Terms and Syntax:

All commands must be sent in upper case as shown. Lower case will not be recognized.

The syntax and action of most commands reflects their development with a terminal

program. To support legacy syntax, the terminal interactivity remains.

<CR> = carriage return = character 13

The remote control syntax is that of an HTML-style tag wrapping each command name

and a carriage return:

<COMMAND_NAME > <CR>

In order that differing terminal protocols may be supported, <LF>s (character code 10

decimal) are filtered out of the stream for most commands.

The prompt returned by the ApHandheld is:

There are, furthermore, several return codes that may precede the prompt.

COMMAND RESPONSES: (delimited from the prompt by a <CR>)

•‘>’ – Ready Prompt

•‘=’ – multichar command executed successfully.

• ‘#’ – data or parameters were out-of-range for the given command.

•‘*’ – command not usable in the current mode. Set-preset command only operates

in BpTest mode, for instance. Some commands require a purchased upgrade, etc.

• ‘?’ – COMMAND_NAME is not recognized as a valid command.

•‘$’ – checksum error in data that was sent.

•‘@’ – data has overflowed (data was truncated to prevent a memory leak).

•'!' - command has no current context, not usable in this mode or at this time.

•‘~’ – Busy

•‘^’ – Time out

The software that drives an ApHandheld must process all these return characters.

Using Commands

The remote-control user of an ApHandheld utilizes the following command to enable

remote-control:

<> <CR>

In response to this, the user should see the message:

<USB_MULTICHAR_CMDS_ENABLED>

The first line returned is a comment to the user “<USB…>” which indicates the

command parser is awake.

The ‘=’ indicates the command was recognized and hence was executed successfully.

The ‘>’ is the prompt char, indicating the unit is waiting for another command.

Argument versus Argument-less commands

Commands that take arguments give their arguments Carriage-return delimited from

the command. Where this documentation shows arguments in braces

[argument1,argument2] it is listing acceptable variables. These are to be entered

without the braces.

Sent:

<ARGUMENT_COMMAND > <CR>

ARGUMENT1 <CR>

Received:

=<CR> --OR-- (error code if error occurred) <CR>

Sent:

<ARGUMENT_LESS_COMMAND > <CR>

Received:

=<CR> --OR-(error code if error occurred) <CR>

Note: Synch on the ‘>’ character (prompt character) to indicate a

command completed. The previous line in the stream will have the result

of the operation (‘=’, ‘*’, etc).

Commands

Start Remote Control:

Send: <> <CR>

Recv: <USB_MULTICHAR_COMMS_STARTED> <CR>

=<CR>

Keypad Disable / Enable Commands

Send: <KEYPAD_OFF> <CR> --OR-- <KEYPAD_ON> <CR>

Recv: ‘=’ <CR>

Use of this is highly recommended. These commands turn processing of the physical

keypad off/on so that the user does not have to worry about keypad inputs interfering

with the execution of a remote control session.

Get Features

Primarily a troubleshooting aid for factory support.

Returns a HEX value which reflects the configuration and software options loaded.

Send: <GET_FEATURES> <CR>

Recv: Features = 6008 Hex

Set Device ID

Note: This command is given for convenience to the end-user. There exists a utility,

distributed for free by FtdiChip.com that allows the USB chip inside the APHandheld device

to be programmed with a custom device id. Programmers using FTDI’s API may use this to

identify devices. This is simpler than opening the port and then querying the device. The

user does not even have to open the port if it’s not the device they are looking for.

This allows users to set their device ID so that a group of them may be controlled

remotely. Software configured to control a group of devices can requisition each device

for its informal name (or a more formal ID, such as “Factory1”, for instance) . This way,

it does not matter which USB port is used to communicate with a device, even if it is on

aRadio-linked USB hub; it just matters that we know which device ID we are talking to.

Some users will prefer to ask for the serial number to determine which device is which.

Send: <SET_DEVICE_ID> <CR>

Sparky <CR> “Sparky” is listed here as an example name

Recv: ‘=’ on success

‘@’ on overflow.

Get Device ID

Send: <GET_DEVICE_ID> <CR>

Recv: “Sparky” – if device id has been set

“*” – if device id has not been set
