EXTERNAL AIR OFF/ON
Pushbutton Switch: Use with
nominal 50-PSI compressed gas
source. Default value is "OFF".
Status displayed in LCD (beneath
Pushbutton Switch).
SIGH OFF/ON Pushbutton Switch: Default value is "OFF". When
set to "ON", first breath delivered is a SIGH, then once every 100-
breaths or 7-minutes thereafter (whichever occurs first). Each
SIGH equals 150% of Inspiration Time setting, delivered volume is
increased by 50%. Status displayed in LCD (beaneath Pushbutton
Switch).
PEEP OFF/ON-SET Pushbutton Switch:
Sets internally-generated PEEP setpoint.
Default value is "OFF". Range is from 0 to
20 cmH O. Value increases by 1, each
2
time pushbutton is pressed. Value displayed
in LCD (beneath Pushbutton Switch).
PRESSURE PLATEAU OFF/ON Pushbutton Switch:
Default value is "OFF". When switch is pressed,
PLATEAU value is automatically referenced 10
cmH O less than HIGH PRESSURE ALARM/PEAK
2
INSPIRATORY PRESSURE RELIEF Control setpoint.
Plateau range is 5 to 90 cmH O. Value displayed in
2
LCD (beneath Pushbutton Switch).
HIGH PRESSURE ALARM/PEAK INSPIRATORY PRESSURE RELIEF Control:
Sets threshold value for High Pressure Alarm/Peak Inspiratory Pressure Relief.
Range is 15 to 100 cmH O. Default is current postion of Control. Activates
2
when inspiratory pressure exceeds setpoint any time during 4-consecutive
ventilations. Value displayed in LCD (beneath Control).
LOW PRESSURE ALARM Control: Sets threshold
value for Low Pressure Alarm. Range is 0 to 50
cmH O. Default is current postion of Control.
2
Activates when inspiratory pressure does not exceed
setpoint at any time during 2-consecutive ventilations.
Value displayed in LCD (beneath Control).
PEAK and MEAN AIRWAY PRESSURE Indicators: Display
the Peak and MEAN Airway Pressure of the previous breath.
HIGH AIRWAY PRESSURE ALARM Setpoint Indicator: Indicates current
setting of HIGH PRESSURE ALARM Control adjacent to Digital Bar Graph.
DIGITAL BAR GRAPH Indicator: Provides continuous display of airway
pressure. Range is from -10 to +100 cmH O, vertical resolution 2 cmH O/bar.
22
LOW AIRWAY PRESSURE ALARM Setpoint Indicator: Indicates current
setting of LOW PRESSURE ALARM Control adjacent to Digital Bar Graph.
P Indicator: Displays the most recent 12-seconds of airway pressure
aw
information. Vertical axis is calibrated to coincide with adjacent DIGITAL
BAR GRAPH. Horizontal axis is calibrated in 1-second intervals.
AIR/OXYGEN MIXER Control: Sets FIO when ventilator is connected to
2
external 50-PSI oxygen source. Range is 21 to 100%. Default is current
position of Control. FIO value displayed in LCD (above Control).
2
TIDAL VOLUME Control: Sets Tidal Volume. Range is based on gas flow not
exceeding 60 LPM (1000 ml/sec). Default value is current position of Control.
Set and delivered Tidal Volume alternately displayed in LCD (above Control).
MODE Selector Switch: Applies operating power to ventilator for Assist-Control
(A/C), Synchronized Intermittent Mandatory Ventilation (SIMV), Continuous
Positive Airway Pressure (CPAP), or Transducer Calibration (CAL) modes.
CHARGE Indicator: Green LED, illuminates when battery recharging current
is flowing. LED does not remain illuminated when battery is fully charged.
ALARM Indicator: Activates for all alarm conditions except a System Failure Alarm. Red
LED flashes on/off when alarm is not muted; stays on continuously when alarm is muted.
The LED Indicator is accompanied by a pulsing tone that remains on until the alarm is muted.
SYSTEM FAILURE Indicator: Activates when CPU is forced to stop operation or a CPU failure
has occurred. Red LED illuminates continuously and is accompanied by a continuous audible
tone that cannot be muted. A System Failure will cause the LCD to blank.
MANUAL BREATH/TRIGGER: Delivers a Manual Breath equal to one complete ventilatory cycle in A/C and
SIMV. In CPAP, the Manual Breath delivers gas at a 30 LPM flow rate, for 1.67-seconds, pressure limited to
40 cmH O. The Manual Trigger is operational when a System Failure has occured. Gas will flow at a rate of
2
30 LPM, pressure limited to 40 cmH O, for as long as the Pushbutton Switch is pressed.

ALARM MUTE/CANCEL Pushbutton
Switch: The alarm catagory
determines what effect pressing this
switch will have. It will mute an
audible operating alarm signal,
cancel an advisory alarm signal, or
cancel specific alarms such as
APNEA or EXTERNAL POWER FAIL.
A typical mute is 30-seconds, special
alarms have longer mutes.
MODE Indicator: Displays current
setting the MODE Selector Switch
V Indicator: Displays Minute Volume
min
(in liters), in the A/C mode.
INSPIRATION/EXHALATION Indicator:
Alternately displays the inspiration and
exhalation phase of mechanical and/or
spontaneous breaths.
POWER INFORMATION CENTER: A 2-line
area that displays current status of external
power, internal power, and fuses. The EXT
PWR line blanks when the ventilator is not
connected to an external power source.
ALARM MESSAGE CENTER (AMC): A
centralized location for displaying up to 4-lines
of alarm message information. Up to 2-alarms
with, short messages, may be displayed
simultaneously. If more than 2-alarms occur
simultaneously, only the name of each alarm is
displayed (as shown below in boldface).

VENTILATION RATE Control:
Sets mechanical ventilation rate
for A/C and SIMV modes. Range
is 1 to 150 BPM. Default is
current position of Control. Value
displayed in LCD (above Control).
INSPIRATION TIME I:E RATIO Control:
Sets inspiratory duration for all ventilator-
generated breaths. Range 0.1 to 3.0-
seconds maximum. Usable range is
limited by VENTILATION RATE Control
setting (Inverse I:E is not permitted). Fully
counterclockwise position enables fixed
1:2 I:E Ratio. Default is current position of
Control. Combination of inspiration time and
I:E Ratio is displayed in LCD (above Control).
