Apnea Ventilation in APRV / BiPhasic
Apnea ventilation is available in APRV / BiPhasic. If the patient does not initiate a spontaneous effort, or the ventilator
does not time cycle between pressure levels before the apnea interval has elapsed, the ventilator will alarm for apnea
and begin apnea ventilation at the apnea ventilation settings. A spontaneous effort from the patient or a transition in
baseline pressure will reset the apnea alarm and timer and return the ventilator to APRV / BiPhasic ventilation.
