Ventilator controls
Flow Trigger Level
This parameter sets the minimum flow detected by the ventilator which triggers
the ventilator to deliver a mechanical breath to a spontaneously breathing
patient. Only active in SIMV and PSVPro modes.
I:E
This control sets the inspiratory to expiratory ratio of mechanical breaths
supplied to the patient.
Insp. Termination Level
This parameter sets the percentage of the peak inspiratory flow where the
ventilator stops a pressure supported breath. Only active in SIMV and PSVPro
modes.
PEEP
This control sets the positive end expiratory pressure. This is only available
during mechanical ventilation, but the control can be set at any time.

patient injury can result.
Pinspired
This control sets the amount of pressure delivered to the patient in each
pressure controlled breath.
Plimit
This control sets the maximum (and sustained) airway pressures tolerated in
the patient’s breathing system.
• If the high airway pressure limit is reached, inspiration stops and
exhalation starts.
• The limit is an absolute value. There is no offset for PEEP pressure.
Note: Pmax is the peak sensed airway pressure; Plimit is the airway pressure
limit set with front panel controls.
Psupport
This control sets the delivered pressure during pressure support ventilation.
Only active in SIMV and PSVPro modes.
Rate
This control permits you to set the frequency of mechanical breaths delivered
to the patient. It also establishes the apnea delay time in the PSVPro mode.
Tinspired
This control sets the time in seconds for each timed inspiration. Only active in
SIMV and PSVPro modes.
