7. Operating the AHP300 Ventilator :
The following steps will guide a person through the setup and operation of the AHP300
ventilator.
Connecting to an Oxygen Source:
Located on the left side of the AHP300 are 2 diameter index safety system (DISS) fittings,
one for Oxygen and one for Medical Air. Connect the appropriate 3.4 bar (344 kPa) (50 psi)
gas source with a minimum of 80 LPM flow capacity to these fittings. The AHP300 may be
used without an external gas source. The AHP300 has an internal compressor that can be
used to supply ambient air to the patient.
Warning: Proper tidal volumes may not be provided with a gas source
not providing a minimum of 80 LPM at 2.8 bar (280 kPa) (40 psi).
Warning: This device operates with medical gases under pressure,
including oxygen. Do not use this device while smoking or near open
flames. Do not use this device or operate near flammable materials.
Warning: Do not use on this device in the presence of flammable
anesthetics.
Warning: Verify that there are no noticeable leaks after connection to
the 3.4 Bar (344 kPa) (50 PSI) Medical O2 or Medical Air source.
Caution: In order to provide optimal performance, check all gas
supplies to assure only medical grade gas is used.

9
Connecting the patient breathing circuit:
Located on the right side of the unit is a 22mm patient connection port for a patient breathing
circuit. Install the corrugated tubing over the connector so that it is on securely. The tubing
will not pull off easily when properly installed. Connect the small tube without a connector to
the small barb labeled Exhalation Valve. Connect the tube with a connector to the blue barb
labeled Patient Airway.
Warning: Do not use unapproved patient circuits as loss of
performance may result.
Ventilator Patient Circuit
The AHP300 uses a universal single limb ventilator patient circuit (pictured below).
Allied Healthcare Products Adult Circuit
Part number L599-600
Dead space = 64.1 ml*
Exhalation resistance < 6 cmH2O ^
(Approximately 4 at 60 LPM)
(Approximately 3 at 30 LPM)
Allied Healthcare Products Pediatric Circuit
Part number L599-650
Dead space = 9.2 ml*
Exhalation resistance < 6 cmH2O ^
(Approximately 4 at 60 LPM)
(Approximately 3 at 30 LPM)

10
*Too large of an apparatus dead space can affect the oxygen and other gas levels delivered
to the patient. The addition of accessories may impact the dead space and must be
considered when they are used.
^Addition of accessories may impact the exhalation resistance.
Do not use circuits with “anti-static” or electrically conductive tubing or hoses.
Warning: Ventilator patient circuits may become contaminated during use. To
prevent cross contamination do not reuse patient circuits without proper
disinfecting. Never reuse a “single patient use” ventilation circuit.
Always verify the ventilator circuit is not leaking by checking the connections to ensure they
are pushed on completely. Verify the exhalation valve is on tight and not leaking during
breath delivery.
Installation of a mask to the patient circuit is done by pushing the mask onto the end of the
90degree elbow at the patient end of the circuit as shown below.
Another option is use an exhalation filter to limit the spread of bacteria. L599-200 exhalation
filters may be used as shown below.
Additional exhalation resistance will be experience when using an exhalation filter. The
resistance based on flows is listed below.

Turn the ventilator “ON” by rotating the knob in the “Power” section of the control panel to the
“│” position.
Select the Desired Ventilation Mode:
If the control lock is activated as shown below it must be deactivated before any adjustments
can be made. This is done by pushing the control lock button and the light will turn off to
signify control lock is no longer active. Pushing the control lock button when the control lock
is not active will activate the control lock as indicated by the light above the button.
Push the Mode Selection button and the current mode (for example Volume AC) will begin to
flash. Using the Parameter/Mode adjustment buttons you can move the flashing light to the
mode you desire. Push the mode selection button a second time and that mode will become
the active mode of ventilation. If you do not push the mode selection button a second time
after selecting a mode the ventilator mode change will time out in 5 seconds and exit the
mode selection process. The ventilator will stay in the current mode of operation.

Warning: A CBRN Filter is required when the ventilator compressor is
used in an environment where the air is not safe to breath.
You can then change the ventilation parameters by pushing the button next to the parameter
you want to change and then use the parameter/mode adjustment buttons to change the
value.

13
For example the inspiratory time can be adjusted by pushing the button labeled “I. Time”.
When you push the button the display will begin to flash, the value will change each time one
of the parameter adjustment buttons is pushed. The inspiratory time may be adjusted from .5
to 2.0 seconds. If the ventilator is in a volume mode and the new inspiratory time is too short
or long for to achieve the set tidal volume the light next to the tidal volume setting will come
on and the inspiratory time will not be changed to a setting that does not allow the current
tidal volume setting. The tidal volume must be changed if that inspiratory time is desired.
The following table lists the tidal volumes and BPMs that may be used based on the set
inspiratory time.

The AHP300 has a flow range from 5 to 60 LPM in volume control mode.
In pressure control mode a Peak Inspiratory pressure (PIP) from 15 to 55 cm H2O is set. In
this mode the peak flow may be greater than 80 LPM and the flow will vary during the breath.
The flow rate will be higher in the beginning of the breath and lower as the airway pressure
approaches the peak inspiratory setting. See section 8 for more detail on breath types.
As the BPM or Inspiratory time is adjusted the I:E ratio will be updated on the ventilator
display. This is the calculated ratio of the inspiratory time to the expiratory time. The number
displayed indicates how much longer or shorter the expiratory time is compared to the
inspiratory time. For example if a 2 is displayed it means the expiratory time is 2 times as
long as the inspiratory time. See section 14 for more detail.
The % O2 indicates the percentage of oxygen in the gas delivered to the patient. For
example, “100” indicates that the delivered gas is all oxygen, while “21” indicates that it is all
air. This value is adjustable from 21 to 100 with an accuracy of 12% of the setting. For
example a %O2 setting of 50 would have a tolerance of ±6 giving a potential range of 44 to
56%. If you select a value that cannot be achieved due to a gas supply not being connected
or having low pressure, a gas source alarm will sound. If only oxygen is connected, the
AHP300 will use the internal compressor to supply air and there will not be an alarm. If you
select a %O2 of 70 when only oxygen is available, the ventilator will activate the internal
compressor to provide the required air flow so that the set tidal volumes can be delivered.
PEEP may be used in any volume or pressure mode. PEEP (positive end expiratory
pressure) will hold a set pressure at the end of exhalation portion of a breath. This pressure
keeps the lungs partially inflated to help the exchange of oxygen through the alveoli. The
PEEP setting may be set from 0 to 25 cm H2O.

14
The PEEP/CPAP setting also controls the pressure level for CPAP (Continuous Positive
Airway Pressure). See section 9 for more detail.
Safety Pressure Relief:
This ventilator has a mechanical pressure relief set at ≤85 cm H2O (maximum limited
pressure). When the airway pressure reaches this limit the valve will open and gas will be
vented to prevent the pressure from continuing to build. This is a redundant safety device as
the high airway alarm limits the maximum pressure.
Warning: Preset tidal volumes may not be delivered when the pressure
relief setting is reached. Inspiratory times will remain constant,
however no additional tidal volume will be delivered after the pressure
relief limit is reached.
Connect the patient breathing circuit to the patient:
The patient breathing circuit has been designed to fit with an oxygen mask (22mm outside
diameter) or endotracheal tube (15mm inside diameter). Follow the established guidelines
for maintaining the patient’s airway.
Verify the patient is receiving good ventilation:
Once the patient is connected to the ventilator the patient should be observed to make sure
they have adequate chest rise and fall. The chest rise should be even and should return to a
normal position. If the patient does not have adequate chest rise check the tidal volume or
pressure control setting, patient connections and examine the patient for a possible
obstruction of the airway or other injury. The patient should be monitored to make sure they
are receiving proper ventilation.
The airway pressure display “PIP” should be observed to make sure the patient is receiving
adequate positive pressure ventilation. If the airway pressure display reading is low during
the delivery of a breath and the chest rise is also low, check the tidal volume setting, patient
connections and examine the patient for a possible obstruction of the airway or other injury.
The airway pressure display reading should also be observed to make sure it is not too high.
Common numbers used in practice are a maximum of 20 cm H2O for and unprotected airway
and 30 cm H2O for a protected airway. Higher pressures may be required based on the
patient’s condition and you should always follow the physician’s instructions. A high reading
with pressure limit alarm may indicate a blocked airway or a stiff lung.
Spontaneous Breathing by the Patient:
Should the patient begin to breathe spontaneously the AHP300 will sense this breath and
deliver the breath per the ventilator setting. The LED (light) indicating a spontaneous breath
by the patient will come on after the spontaneous breath is delivered by the ventilator. The
ventilator will also display the number of spontaneous breaths delivered in the past minute.
The trigger pressure level for a spontaneous breath may be adjusted using the trigger level
setting. The adjustment range is from 1 to 5 and represents a range from 1 to 5 cm H2O.
See assist control and synchronized intermittent mandatory ventilation sections for more
detail on how the ventilator reacts to a spontaneous breath.

15
For safety, the ventilator contains an internal anti-suffocation valve.
Warning: A CBRN Filter is required when the ventilator compressor is
used in an environment where air is not safe to breath.
8. Ventilation Modes:
Volume Control: In volume control the ventilator will deliver a set tidal volume at a time
cycled interval determined by the inspiratory time and respiratory frequency (BPM)
settings. The breath will have a constant flow rate. The flow rate required is a function of
the tidal volume (Vt) and the inspiratory time (Ti). The patient’s airway pressure will
steadily increase during the breath delivery.
The graphs below shows a typical flow versus inspiratory time graph for a volume
controlled breath. The second graph shows a typical patient airway pressure versus
inspiratory time pattern.

Pressure Control: In this mode the ventilator will deliver flow to the patient until a set
pressure is reached. The flow rate will be variable and will slow down as the airway
pressure approaches the set pressure. The ventilator will measure the time and
pressures at various points in the breath and then adjust the flows automatically to
achieve the pressure curve shown below. If the set pressure is not reached the breath
will terminate based on the inspiratory time selected. If the set peak inspiratory pressure
is reached before the end of the inspiratory time the, the flow will stop but exhalation will
not happen until the end of the inspiratory time. The rate of breathing will be time cycled
based on the BPM rate and inspiratory time settings.
Continuous Positive Airway Pressure (CPAP) Mode: The ventilator will maintain the
set pressure through inhalation and exhalation. There will be a slight drop in pressure at
the start of inhalation and a slight increase at the start of exhalation. The rate of breathing
will be based on the patient’s spontaneous respiratory rate. Pressure support may be
used to produce a higher airway pressure during inhalation (BI-PAP).

Pressure Support:
In this mode the ventilator will deliver flow to elevate the pressure to the pressure support
setting and maintain it at that pressure until the flow required to maintain the pressure is
less than 2 LPM . This breath has a maximum inspiratory time per the Inspiratory time
setting in the volume or pressure control mode. Pressure support is only activated on
patient initiated breaths that are not receiving volume or pressure control. Pressure
Support may be used with Volume SIMV, Pressure SIMV and CPAP.
Bilevel Positive Airway Pressure (BIPAP): BIPAP may be achieved on this ventilator
by using pressure support in combination with CPAP. To achieve BIPAP the Pressure
Support setting would be 15 and the CPAP setting would be 10 as an example. This
would produce an airway pressure of 15 cmH2O during inhalation and 10 cmH2O during
exhalation.
Seamless Transition between Volume and Pressure Modes
To facilitate rapid and safe adjustment of therapy by respiratory care professionals the
AHP300 incorporates what we call “Seamless Mode Transition”.
When moving from a pressure regulated mode to a volume regulated mode, the prior
settings for BPM and Inspiratory Time remain the same and the Tidal Volume that has
been measured for the last breath in pressure control mode becomes the initial Tidal
Volume for the new volume control mode. Likewise, when the practitioner moves from a
volume controlled mode to a pressure controlled mode, the measured Peak Inspiratory
Pressure in the volume mode will become the PIP setting for the pressure control mode.
In short, the patient sees no change in the ventilator parameters delivered until further
adjustment by the RCP, and in that sense, we term the transition seamless.

18
9. Breath Types:
Assist Control (AC): The ventilator will guarantee that the numbers of breaths given will
be equal to or greater than the BPM setting. The patient may trigger additional breaths.
When the ventilator detects a spontaneous breath it will deliver a breath per the volume or
pressure control settings.
The ventilator will allow a minimum exhalation time of .5 seconds and will not allow a
spontaneous breath to be triggered during this time. The ventilator will include a light to
signify the delivery of a spontaneous breath and display the number of spontaneous
breaths taken during the last minute.
Pressure support is not allowed with this breath type because each spontaneous breath
receives full ventilator support per the volume or pressure control settings.
Synchronized Intermittent Mandatory Ventilation (SIMV): The ventilator will deliver
only the set number of breaths per minute per the volume or pressure control settings. If
the patient is breathing more rapidly than the BPM setting the additional breaths will be
demand flow or pressure support (if enabled) breaths.
For example if the BPM is set to 10 the breath period will be set to 6 seconds. During the
6 second period the first breath will be to ventilator settings. Additional breaths will be
demand flow or pressure support (if enabled) breaths. The maximum time from the start
of one breath to the start of the next breath will also be 6 seconds. If the patient is
breathing at a rate slower than the BPM setting, the ventilator will deliver breaths at the
set BPM.
The ventilator will allow a minimum exhalation time of .5 seconds and will not allow a
spontaneous breath to be triggered during this time. The ventilator will include a light to
signify the delivery of a spontaneous breath and display the number of spontaneous
breaths taken during the last minute.

19
10. Programmable Presets:
The ventilator has 2 different programmable presets, Quick Start and Custom modes.
The Quick Start modes are for adult and child and have a button for each mode. There
are 3 Custom modes that can be set up. One must use the Custom Mode button and the
parameter adjustment buttons to select the desired Custom Mode.
Quick Start Modes:
These modes allow the care giving facility or agency to program and store ventilator
settings for quickly establishing initial patient ventilation.
There are 2 Quick Start Mode buttons (Adult/Child) for which the settings may be
customized based on the direction of a physician. The location of the buttons is shown on
the panel below.
Table 1 shows the Quick Start Mode settings as supplied from the factory. However,
before these buttons can be used, the settings must be confirmed or modified by qualified,
trained medical personnel under the direction of a physician. To determine whether the
Quick Start Modes have been confirmed or modified by facility medical personnel, press
the desired Quick Start Mode button (Adult or Child). If the Quick Start Mode button has
been confirmed or modified the settings selected and stored by the qualified medical
personnel will be displayed; if not, the light below the button will flash and the unit will
beep.
Initial Confirmation or Modification of Default Settings:
To begin the initial confirmation/modification process (Initialization), first push down both
Quick Start mode buttons and hold for 3 seconds. The lights below both buttons will
begin to flash. Then press the button for the mode (Adult/Child) you wish to confirm or
modify. The light below that button will now flash rapidly and the other will turn off. The
ventilator will now show the default settings for this button (see Table 1, below).

To modify the settings for the selected mode select the parameter to be adjusted and then
use the parameter adjustment buttons to revise the setting. (These settings may be
changed to any mode on the ventilator.) Once all parameters have been modified to
conform to physician directives, the settings must be stored. To store the settings for the
selected mode (Adult/Child) Quick Start Mode, press and hold the button until the
ventilator beeps, about three seconds. (In the event that you decide to use the factory
default values, you must still store the settings to confirm and to activate the Quick Start
buttons for use.) Once the settings have been stored the button will be initialized and is
ready for use.
Storing New Settings:
To store new settings, hold the Quick Start button you are programming down until you
hear a beep indicating the settings have been stored. This will take approximately 3
seconds. The light below the button will stop flashing and the ventilator will now operate
with the Quick Start settings you just programmed.
If you are in the process of changing the setting of a Quick Start button and decide to
abandon the changes one may either press the “Alarm Silence/Reset” button or cycle
power. This will exit the Quick Start mode programming or revision process and restore
the Quick Start mode button to its previously saved settings.
The process of modifying and storing the settings for a Quick Start button will have to be
done twice, once for button #1 and once for button #2.
These buttons should not be initialized while the ventilator is in use on a patient. The
ventilator will change to the stored settings at the end of the initializing sequence.
Warning: Do not Initialize the “Quick Start mode” while in use on a patient.
Unwanted setting changes may occur.
