When a patient does not breathe spontaneously while in the airway pressure release ventilation (APRV)mode,the pressure-time scalar looks like that of which of the following?

Question

Quizplus · Accepted Answer

The airway pressure release ventilation (APRV)mode is a dual mode of ventilation that allows the patient to breathe spontaneously at two levels of continuous positive airway pressure (CPAP).Both pressure levels are time triggered and time cycled.When the patient is not spontaneously breathing the pressure-time scalar will alternate between the two CPAP levels.The higher pressure,or P_high is set longer than the P_low.The pressure-time scalar for this mode will then appear as pressure-controlled inverse ratio ventilation (PCIRV).
