Final answer:
c.APRV. The statement describes the mode called Airway Pressure Release Ventilation (APRV). In APRV, the baseline pressure is elevated but periodically released to a lower level, allowing the patient to breathe spontaneously.
Step-by-step explanation:
The statement describes the mode called Airway Pressure Release Ventilation (APRV). In APRV, the baseline pressure is elevated to provide continuous positive airway pressure (CPAP) to the patient's lungs. Periodically, the pressure is released to a lower level, allowing the patient to breathe spontaneously.
