Which statement best describes optimal positive end-expiratory pressure (PEEP)?

Question

Quizplus · Accepted Answer

Optimal PEEP refers to the pressure at which static compliance (ability of the lungs to expand) is maximized and oxygen transport is greatest. This pressure level helps to prevent atelectasis (collapse of lung tissue) and improve gas exchange in the lungs. Option B is incorrect because PEEP levels above optimal PEEP can lead to overinflation of alveoli, which can cause lung injury. Option C is incorrect because optimal PEEP helps to evenly distribute volumes throughout the lungs during inspiration and expiration. Option D is incorrect because optimal PEEP allows for equal distribution of volumes during inspiration and expiration.
