ASSEMBLY, INTERCONNECTIONS AND INITIAL ADJUSTMENTS
ASSEMBLY:
Model 754 -No assembly is required before placing this device into operation.
Model 754M -Depending upon contract requirements, battery pack installation may be necessary. Please check
your contract accordingly. If battery pack installation is required, see BATTERY CARE AND RECHARGING
section for instructions.
INTERCONNECTIONS:
CAUTION: Follow interconnection instructions prior to placing this device into service (see Figure 2).
1. For use with external oxygen: connect high pressure oxygen hose between OXYGEN inlet port and a 50-PSI
external oxygen source. Use only medical-grade oxygen (see Figures 5a and 5b).
2. For use with external air: connect high pressure air hose between AIR inlet port and a 50-PSI external air source.
Use only medical-grade compressed air (see Figures 5a and 5b).
3. Connect disposable ventilator circuit to its respective gas outlet, transducer, and exhalation valve connectors on
Model 754/754M Connector Panel. Observe directions included with disposable ventilator circuit (see Figure 4).
The gas outlet contains a leaf valve mounted flush to its inside –it has two purposes. First, should a spontaneously
breathing patient require supplemental flow or the ventilator is not triggering in response to the patient’s breathing
effort, the leaf valve opens allowing entrainment of ambient air (acting as an antiasphyxia valve). Second, should
the gas outlet port or the ventilator circuit become blocked, the leaf valve wedges itself into the large holes it
normally blocks (acting as a protective blow-out valve) to protect the patient and ventilator from excessively high
pressures. Never block (or occlude) the gas outlet port or connected ventilator circuit when the ventilator is
operating. Prior to operation, verify that the leaf valve is properly seated otherwise re-seat before patient use.
Location of Leaf Valve inside AdapterLeaf Valve in position
-ix –
Should valve
dislodge
, use blunt end of a small diameter object to gently push wedged section(s) of leaf valve inward so it
dislodges from peripheral hole(s) and re-seats itself against inner wall of gas outlet connector. Visually verify leaf valve lays
flush against inner wall curvature of gas outlet connector.
Should valvedetach from gas outlet connector, gently grab leaf valve “tail” with tweezers. Insert “tail” from inside of gas
outlet connector through its small hole. Grab“tail” as it passes through small hole. Pull gently on “tail” until you feel it lock
into position. Leaf valve and mating hole have interlocking shoulders causing valve to become locked in place when initially
pulled. Visually verify leaf valve lays flu
sh against inner wall curvature of gas outlet connector.

INTERCONNECTIONS, (cont’d)
4. Connect Universal AC Power Supply, or 12 VDC Power Cable, between EXTERNAL POWER JACK and
external power source (see Figure 5b).
INITIAL ADJUSTMENTS:
Before placing this device into operation, read section entitled OPERATION: DESCRIPTION OF CONTROLS,
VISUAL INDICATORS AND CONNECTIONS. Make control settings and verify device performance prior to
patient use.

SECTION I. OPERATION
INTRODUCTION
User's will find this instrument quite easy-to-learn and operate. The following text presents a brief overview of
device features. A complete understanding of its capabilities and limitations will allow you to take advantage of its
many features.
Your Model 754/754M is a portable, electronically controlled ventilator, compressor, air/oxygen mixer. It is
controlled by an internal microprocessor (CPU) which continuously monitors and displays airway pressure, control
settings, alarm parameters, gas source(s), gas flows, gas blends, and power signals. ACV, SIMV and CPAP modes
are operable with or without PEEP, with or without SIGH. ACV and SIMV are operable with or without Pressure
Plateau. All modes are PEEP and altitude compensable to minimize your patient's work-of- breathing and automatic
ventilatory backup assures continued mechanical support if the patient becomes apneic. An adjustable pressure limit
control limits peak inspiratory pressures and high pressure alarm setpoint.
The Model 754/754M can provide gas mixtures with oxygen content ranging from 21 to 100%. Gases may be
blended from external oxygen (compressed gas cylinder or PTLOX) and internal compressor, or external oxygen
and external compressed air. External compressed air, delivered from an electric compressor, must be oil-less and
filtered. Acceptable input gas pressures may range up to 80-PSI without effecting measurement accuracy or danger
to internal componentry. It is operable in any position; upright, on its side, or lying flat.
Uni-Ventis operable from internal, rechargeable batteries; 11-15 volts DC (negative ground). Its battery pack
may be recharged within the range of either of the aforementioned DC voltages. A Universal AC Power Supply and
12 VDC Power Cable is provided. The Universal AC Power Supply connects directly to AC mains providing 90 to
265 volts, 47 to 440 Hz. An optional Universal AC Power Supply (standard with the Model 754M) connects
directly to AC mains providing 115/230 volts, 50 to 400 Hz (voltage and line frequency sensing is automatic), and
permits use from external DC voltages, ranging from 16 to 30 volts which connect to the secondary input leads
provided. Attachment to a mating connector is required and polarity must be observed. The black input lead is
positive, the white is negative. Do not attach the braided shield. The Model 754/754M does not consume gas for
operating power -all gas is dedicated for patient care.
Your ventilatory system employs a comprehensive alarm system. Alarms are categorized as Operating, Non-

CONTROLS, (cont'd)
EXTERNAL AIR OFF/ON Pushbutton Switch: The EXTERNAL AIR Pushbutton Switch permits you to
manually select external compressed air as your primary air source. When the ventilator is turned ON, its CPU
"samples" the respective gas fitting and looks for an air pressure, greater than 40-PSI. If a lower pressure, or no
pressure is sensed, the LCD will display "OFF" (default value), and the CPU allows operation from the internal
compressor. If a pressure exceeding 40-PSI (+/-2-PSI) is sensed, the LCD will display "ON", and allow operation
from the external air supply. Manually pressing this pushbutton will toggle the display from "OFF" to "ON", or
from "ON" to "OFF". Attempting to select "ON" with less than 35-PSI (+/-2-PSI) present will cause an alarm to
sound. The LCD display area for EXTERNAL AIR is on the top line, immediately below its respective pushbutton
switch. The EXTERNAL AIR OFF/ON display will blank when a SYSTEM FAILURE Alarm occurs.
SIGH OFF/ON Pushbutton Switch: The SIGH OFF/ON Pushbutton Switch permits Uni-Ventto operate with
or without SIGH. When activated, the first ventilator generated breath will be a SIGH. Additional SIGH
ventilations are delivered once every 100 ventilations or 7-minutes, whichever occurs first. Each SIGH ventilation
equals 150% ofthe INSPIRATION TIME setting (and exhalation period), which increases delivered volume by
50%. Proportionately increasing both the inspiration and exhalation time allows Uni-Ventto maintain I:E during
SIGH. As a safety precaution, Uni-Ventdoes not allow the inspiratory portion of a SIGH breath to exceed 3-
seconds. Manually pressing this pushbutton will toggle the display from "OFF" to "ON", or from "ON" to "OFF".
"OFF" is its default value. SIGH becomes disabled ("OFF") in the CPAP mode, or when PRESSURE PLATEAU is
selected ("ON"). The LCD display area for SIGH is on the top line, immediately below its respective pushbutton
switch. The SIGH OFF/ON display will blank when a SYSTEM FAILURE Alarm occurs.
PEEP OFF/ON-SET Pushbutton Switch: The PEEP OFF/ON-SET Pushbutton Switch activates Uni-Vent's
internal PEEP control. When the ventilator is turned ON, PEEP has a default value of 0 cmH2O (no PEEP).
Pressing the pushbutton allows a PEEP value to be manually entered (see section entitled USING POSITIVE END
EXPIRATORY PRESSURE). The LCD display area for PEEP is on the top line, immediately below its respective
pushbutton switch. The PEEP OFF/ON-SET display will blank when a SYSTEM FAILURE Alarm occurs.
PRESSURE PLATEAU OFF/ON Pushbutton Switch: The PRESSURE PLATEAU OFF/ON Pushbutton Switch
permits ACV or SIMV operation with a pressure plateau. When the ventilator is turned ON, PLATEAU is OFF
(default value). Pressing this pushbutton activates a PLATEAU value that is referenced 10 cmH2O below the HIGH
PRESSURE ALARM/PEAK INSPIRATORY PRESSURE RELIEF Control setpoint. Its absolute range is 5 to 90
cmH2O. When this pushbutton is pressed, it will toggle the display from "OFF" to its PLATEAU value, or from its
PLATEAU value to "OFF". PRESSURE PLATEAU becomes disabled ("OFF") in the CPAP mode. The LCD
display area for PRESSURE PLATEAU is on the top line, immediately below its respective pushbutton switch (see
section entitled USING PRESSURE PLATEAU). The PRESSURE PLATEAU OFF/ON display will blank when a
SYSTEM FAILURE Alarm occurs.
HIGH PRESSURE ALARM/PEAK INSPIRATORY PRESSURE RELIEF Control: This control is used to
select the HIGH PRESSURE ALARM and PEAK INSPIRATORY PRESSURE RELIEF setpoint. It has an
absolute range from 15 to 100 cmH2O. When the ventilator is turned ON, the HIGH PRESSURE ALARM/PEAK
INSPIRATORY PRESSURE RELIEF Control setpoint value equals its current position. The LCD display area for
HIGH PRESSURE ALARM/PEAK INSPIRATORY PRESSURE RELIEF Control setpoint is on the top line,
immediately below its respective control. The HIGH PRESSURE ALARM Control setting display will blank when
a SYSTEM FAILURE Alarm occurs.
LOW PRESSURE ALARM Control: This control is used to select the LOW PRESSURE ALARM setpoint. It
has an absolute range from 0 to 50 cmH2O. When the ventilator is turned ON, the LOW PRESSURE ALARM
Control setpoint value equals its current position. The LCD display area for the LOW PRESSURE ALARM
Control setpoint is on the top line, immediately below its respective control. The LOW PRESSURE ALARM
Control setting display will blank when a SYSTEM FAILURE Alarm occurs.

CONTROLS, (cont'd)
VENTILATION RATE Control: The VENTILATION RATE control setting determines the mechanical
ventilation rate for ACV and SIMV operation. It is not operable in CPAP (RATE = 0). Its range is from 1 to 150
breaths per minute (BPM). When the ventilator is turned ON, the VENTILATION RATE Control setpoint value
equals its current position. The LCD display area for VENTILATION RATE Control setpoint is on the bottom line,
immediately above its respective control. During APNEA, the RATE Control setting and its LCD display will
change to 12 BPM. The VENTILATION RATE Control setting display will blank when a SYSTEM FAILURE
Alarm occurs, or the CPAP mode is selected.
INSPIRATION TIME/I:E RATIO Control: The INSPIRATION TIME/I;E RATIO Control sets the inspiratory
duration of all ventilator-delivered breaths. It is adjustable in 0.1 second increments from 0.1 to 3.0 seconds
maximum. Its usable range is limited by the VENTILATION RATE Control setting. Inverse I:E Ratio's
(inspiratory time is greater than expiratory time) are not permitted. (See section entitled ALARM FUNCTIONS). A
default I:E ratio of 1:2 is activated when this controlis turned to its fully counterclockwise position. When the
ventilator is turned ON, the INSPIRATION TIME/I:E RATIO Control setpoint value equals its current position.
Setting INSPIRATION TIME causes the resulting I:E RATIO to be calculated. Setting the default I:E RATIO (1:2)
causes the INSPIRATION TIME to be calculated when VENTILATION RATE settings are changed. Inspiration
time and I:E ratio are simultaneously displayed in the LCD. The LCD display area for INSPIRATION TIME/I:E
RATIO Control setpoint is on the bottom line, immediately above its respective control. The INSPIRATION
TIME/I:E RATIO Control setting display will blank when a SYSTEM FAILURE Alarm occurs or CPAP is
selected. It will blink during INVERSE I:E conditions.
TIDAL VOLUME Control:The TIDAL VOLUME Control allows gas to be delivered over a wide range. Its
maximum flow is equivalent to approximately 1000ml/sec (60 LPM). TIDAL VOLUME may be obtained from any
of the following gas or gas combinations:
External Air (Cylinder)
External Compressed Air (Compressor)
Internal Air Compressor
External Oxygen and External Air Cylinder or Compressor, or Internal Air Compressor
External Oxygen
Tidal volume is calculated and displayed in milliliters (ml). When the ventilator is turned ON, the TIDAL
VOLUME Control setpoint value equals its current position. Uni-Vent's CPU monitors and adjusts gas flow. Its
LCD initially displays "#### set" TIDAL VOLUME for the first one or two delivered breaths, while the CPU makes
whatever flow corrections are required, then the LCD alternately displays "#### set" TIDAL VOLUME and "####
del" TIDAL VOLUME. The LCD display area for TIDAL VOLUME Control setpoint is on the bottom line,
immediately above its respective control. The TIDAL VOLUME Control setting display will blank when a
SYSTEM FAILURE Alarm occurs or CPAP is selected.
AIR/OXYGEN MIXER Control: The AIR/OXYGEN MIXER Control allows air, oxygen, or mixtures of air and
oxygen to be delivered. It has a range of 21% (all air) to 100% (all oxygen) and may be obtained from the following
gas or gas combinations:
21% FIO2from External Air (Cylinder)
21% FIO2from External Compressed Air (Compressor)
21% FIO2from Internal Air Compressor
21 to 100% FIO2from External Oxygen and External Air Cylinder or Compressor
21 to 100% FIO2from External Oxygen and Internal Air Compressor
100% FIO2from External Oxygen
1 -4

CONTROLS, (cont'd)
When the ventilator is turned ON, the AIR/OXYGEN MIXER Control setpoint value equals its current position.
Uni-Vent's CPU monitors and adjusts gas flow according to the FIO2and TIDAL VOLUME setpoints. In CPAP
mode, FIO2proportions are based on gas flowing at 1000ml/sec. The CPU makes any necessary flow corrections
during the first one or two delivered breaths. Delivered FIO2is displayed in the LCD. The LCD display area for
AIR/OXYGEN MIXER Control setpoint is on the bottom line, immediately above its respective control. The
AIR/OXYGEN MIXER Control setting display will blank when a SYSTEM FAILURE Alarm occurs. It will blink
when an EXT AIR LOW/FAIL, O2LOW/FAIL, or FIO2Alarm occurs.
ALARM MUTE/CANCEL Pushbutton Switch: Depending upon alarm category, the ALARM MUTE/CANCEL
Pushbutton Switch can either mute an audible alarm signal, or cancel a particular alarm function.
Muting: Depressing this switch mutes the audible component of an Operating Alarm condition for a predetermined
period (see ALARM FUNCTIONS). Alarm muting is reset when the current alarm condition no longer applies or
the predetermined mute-period is reached (audible alarm will resound). A new alarm condition overrides a "muted"
pre-existing alarm.
When an alarm causing condition occurs, the LCD ALARM MESSAGE CENTER will display the pertinent alarm
message. The ALARM LED alternately flashes, at the same frequency as the accompanying audible alarm.
Pressing the ALARM MUTE/CANCEL Pushbutton Switch causes the ALARM LED to stay on continuously. It
will resume flashing when the mute period ends.
If a new alarm condition occurs during the mute period of a previous alarm, the new alarm will have no effect upon
the display of that alarm. The new alarm will cause the ALARM LED to alternately flash and respond as previously
described when the ALARM MUTE/CANCEL Pushbutton Switch is pressed.
Canceling: When depressed, the ALARM MUTE/CANCEL Pushbutton Switch cancels the audible component of
an Advisory Alarm condition (see ALARM FUNCTIONS). During an APNEA alarm condition, it will cancel both
the audible and visual APNEA alarms and the controlled ventilations that are automatically invoked at the onset of
apnea. Cancellation of an APNEA alarm allows Uni-Ventto resume operation at the preset ACV, SIMV or CPAP
settings.
MANUAL BREATH/TRIGGER Pushbutton Switch: The MANUAL BREATH/TRIGGER Pushbutton is
operable two ways.
Pressing this control during normal CPU operation, delivers one MANUAL BREATH. Each MANUAL BREATH
is equal to one complete ventilatory cycle consisting of the current INSPIRATORY TIME/TIDAL VOLUME
settings and expiratory period. In the CPAP mode, a manual breath is delivered at a flow rate of 30 LPM, an
inspiratory time of 1.67-seconds, and pressure limited at 40 cmH2O. A MANUAL BREATH cannot be delivered
until airway pressure has reached baseline (zero or PEEP). Each time a MANUAL BREATH is triggered, an
audible beep is heard.
This control functions as a MANUAL TRIGGER backup, if a CPU failure occurs in the primary system. The
MANUAL TRIGGER contains dedicated circuitry capable of providing manually triggered breaths. For as long as
this pushbutton is depressed, the MANUAL TRIGGER delivers a continuous gas flow at 30 liters per minute
(LPM). A pressure relieving mechanism, contained within this circuit, limits peak inspiratory pressure from
exceeding 40 cmH2O.
The MANUAL BREATH/TRIGGER Pushbutton is protected against accidental contact by a circular guard.
MODE Selector Switch (OFF-A/C-SIMV-CPAP-CAL): The MODE SELECTOR Switch provides operating
power in the ACV, SIMV, CPAP, and CAL positions.
Turning the MODE SELECTOR Switch from OFF to A/C, SIMV, or CPAP causes the microprocessor to perform
a "SELF-CHECK" (see section entitled SELF-CHECK) before initiating operating in the selected mode. Ventilator
operation will not begin until "SELF-CHECK" is successfully completed. Calibration of the airway pressure
transducer is permitted in the CAL position only (see section entitled TRANSDUCER CALIBRATION).

ALARM INDICATORS
The LCD display allocates up to 4-lines of alarm message information in a dedicated area. This dedicated area is
called the ALARM MESSAGE CENTER (AMC). Each alarm is displayed in the LCD except for the ALARM
Indicator and SYSTEM FAILURE LED's. The ALARM Indicator LED illuminates, and alternately flashes ON and
OFF, whenever an alarm causing condition other than SYSTEM FAILURE occurs. An audible signal accompanies
each alarm. Alarms are categorized as OPERATING, NON-OPERATING, or ADVISORY (for detailed
information on alarms, see section entitled ALARM FUNCTIONS). When the audible signal is muted during an
OPERATING ALARM, the ALARM Indicator LED remains illuminated, but stops flashing, during the mute
period. During an ADVISORY ALARM pressing MUTE/CANCEL turns the ALARM Indicator LED OFF.
