May be set from Off to 50 cmH

O above baseline using the UP and DOWN Arrows. When pressure support is on, it
pressurizes spontaneous breaths up to the pressure support setting. When this pressure is achieved, the exhalation valve is
allowed to return to baseline pressure, but flow remains on for the duration of a normal assisted breath as set by the RATE
and TIDAL VOLUME controls.
NOTE: Pressure Support is only active during SIMV and CPAP. It is disabled in Assist Control
and when using Constant Flow.
R A T E
Sets the normal respiration rate. It is adjustable from 5 to 150 bpm. When in SIMV, this changes to SIMV RATE and when
in CPAP, to BACKUP RATE.
S I M V R A T E
When in SIMV mode, the RATE key becomes the SIMV RATE key. It sets the rate at which assisted breaths are given in the
SIMV mode. It may be set from 0.6 to 50 bpm. This rate is also the backup rate in the event of apnea.
WARNING: When in SIMV, it is important to always set a correct SIMV RATE,
TIDAL VOLUME and FLOW to insure proper ventilation in case the patient
becomes apneic.
Note: Be aware that the SIMV rate is also the backup rate which is the rate the patient will get in the
event of apnea.
B A C K U P R A T E
Sets the rate at which backup breaths are delivered when in CPAP mode in the event of apnea.
WARNING: When in CPAP, it is important to always set a correct BACKUP RATE,
TIDAL VOLUME and FLOW to insure proper ventilation in case the patient
becomes apneic. When in CPAP with Constant Flow, this is inactive.
T I D A L V O L U M E ( T V )
Sets the volume of gas delivered during assisted or controlled inspirations. It is adjustable from 5 to 750 ml. This key may
be changed to set inspiratory time rather than tidal volume by selecting inspiratory in the SETUP menu. The Setup Menu is
accessible only when the unit is turned on and before any key has been pressed. Press the Setup key and then press
TV/INSP. The currently preferred parameter, Tidal Volume in this case, will be highlighted. Press INSP TIME if you want
to set an inspiratory time rather than tidal volume. If INSP TIME is chosen, you will also be given a choice of displaying TV
or not (see I, E, I/E KEY below). Return to the Main Menu by pressing the Setup Menu key and then the Main Menu key
twice. INSP will now be displayed where TV had been.
With Constant Flow on, this key changes to INSP and sets inspiratory time only.
I N S P
Sets the inspiratory time. It may be set from .1 – 3 seconds. This key may be changed to set tidal volume rather than
inspiratory time by selecting TV in the SETUP menu. The Setup Menu is accessible only when the unit is turned on and
before any key has been pressed. Press the Setup key and then press TV/INSP. The currently preferred parameter, INSP
TIME in this case, will be highlighted. Press TIDAL VOLUME if you want to set a tidal volume rather than inspiratory
time. Return to the Main Menu by pressing the Setup Menu key and then the Main Menu key twice. TV will now be
displayed where INSP had been. If INSP is chosen, you will also have the choice of displaying the set tidal volume or not
(see I, E, I/E Key below).
I , E , I / E K E Y
This is a display key for informational purposes only. It cannot be used to set any parameter, but rather is used to display
the corresponding inspiratory time, expiratory time and I:E ratio, which result from setting the Rate, Tidal Volume (or INSP,
if available) and Flow. When INSP replaces TV in the key above, as explained in the section defining the Tidal Volume key,
then TV (set Tidal Volume) is displayed here rather than Inspiratory time. If the user would rather not see the set Tidal
Volume here when using the INSP setting, then this may be turned off in the SETUP Menu. Refer to the SETUP Menu
instructions (Section V, A-3) for further information. Additionally, segments of this key will indicate alarm conditions as
defined in the ALARMS section of this manual.
F L O W K E Y
Displays the inspiratory flow that is set with the L/min (Flow) knob. It may be set from 0 – 15 lpm.
