Apnea ventilation is available in APRV/BiPhasic mode. If the patient does not initiate a
spontaneous eort or the ventilator does not time cycle between pressure levels before the
apnea interval has elapsed, the ventilator alarms for apnea and begins apnea ventilation
at the apnea ventilation settings. A spontaneous eort from the patient or a transition in
baseline pressure resets the apnea alarm and timer and returns the ventilator to APRV/
BiPhasic ventilation.
Primary controls: Active in APRV/BiPhasic mode are Time High, Pressure High, Time Low,
Pressure Low, Pressure Support, Flow Trigger and %O

Advanced settings: Available in APRV/BiPhasic mode are T High PSV, T High Sync,
T Low Sync, Volume Limit, Pressure Support Rise, Pressure Support Cycle, Pressure Support
Tmax, Bias Flow and Pressure Trigger.
*APRV/BiPhasic mode is available for adult and pediatric patients only.
