The increased work of breathing associated with auto-positive end-expiratory pressure (PEEP) during mechanical ventilation is due to:
I.hyperinflation or impaired contractility of the diaphragm
II.large alveolar pressure drops required to trigger breaths
III.increased volume of the intrathoracic airways

Question

Quizplus · Accepted Answer

Auto-PEEP can lead to hyperinflation, impairing diaphragm contractility, and requires larger alveolar pressure drops to trigger breaths, increasing the work of breathing.
