Question

Quizplus · Accepted Answer

Auto-PEEP occurs when there is incomplete expiration before the next breath. This can be caused by various factors, including high expiratory Raw, high inspiratory flows, and inadequate expiratory time. Choice A includes only the first two factors, which are incorrect because the third factor of inadequate expiratory time is also a contributing factor to auto-PEEP. Therefore, the correct answer is B, which includes the two correct factors of high expiratory Raw and inadequate expiratory time.
