How does the ventilator function of positive end-expiratory pressure assist the patient?

Question

Quizplus · Accepted Answer

Positive end-expiratory pressure (PEEP) keeps pressure in the lungs after expiration, which helps to keep the alveoli open and prevent them from collapsing. This improves gas exchange and can reduce the need for higher levels of ventilator support. Choice B, C, and D are incorrect as PEEP does not deliver oxygen, allow patient control of expiratory pressure, or deliver inhalant medication.
