Question

In which mode of ventilatory support does the patient breathe spontaneously at an elevated airway pressure, with short, intermittent decreases in pressure to a lower level?

A) volume-assured pressure-supported ventilation


B) pressure-controlled inverse ratio ventilation (PC-IRV)


C) bilevel positive airway pressure


D) airway pressure release ventilation (APRV)

Answer 1

Airway pressure release ventilation (APRV) is the mode of ventilatory support in which the patient breathes spontaneously at an elevated airway pressure, with short, intermittent decreases in pressure to a lower level.

Step-by-step explanation:

The mode of ventilatory support in which the patient breathes spontaneously at an elevated airway pressure, with short, intermittent decreases in pressure to a lower level, is airway pressure release ventilation (APRV). In APRV, the patient is able to breathe at a high continuous positive airway pressure (CPAP) level, which helps to maintain lung recruitment and improve oxygenation. During brief release periods, the pressure is lowered, allowing for exhalation.
