What factors contribute to the development of auto-positive end-expiratory pressure (PEEP)?
I.high expiratory Raw
II.high inspiratory flows
III.inadequate expiratory time

Question

Quizplus · Accepted Answer

High expiratory resistance (Raw) can cause air trapping and PEEP, while inadequate expiratory time can contribute to air trapping and reduce the time available for exhalation, leading to increased PEEP. Although high inspiratory flows can affect PEEP, it is not a significant contributor compared to the other two factors. Therefore, the correct answer is B) I and III.
