Detrimental effects of auto-positive end-expiratory pressure (PEEP) include all of the following except:

Question

Quizplus · Accepted Answer

AutoPEEP or inadvertent PEEP can lead to increased pulmonary pressures, which in turn may cause harm to alveolar-capillary membranes, leading to increased pulmonary vascular resistance. However, PEEP is also used to decrease pulmonary vascular resistance in some patients, such as those with acute respiratory distress syndrome (ARDS), as it can recruit collapsed lung units and improve oxygenation. A and B are correct in describing potential detrimental effects of PEEP, whereas D is incorrect since PEEP can actually increase venous return by increasing intrathoracic pressure and reducing the pressure gradient for blood flow into the thorax.
