Detrimental effects of auto-positive end expiratory pressure (PEEP) include which of the following?
1) Increased work of breathing
2) Increased pulmonary barotrauma
3) Decreased pulmonary vascular resistance
4) Increased venous return

Question

Quizplus · Accepted Answer

Auto-PEEP is the phenomenon where there is incomplete exhalation leading to residual air trapping. This increases the end-expiratory lung volume and dead space volume, resulting in increased work of breathing and pulmonary barotrauma. Auto-PEEP does not decrease pulmonary vascular resistance but may increase venous return.
