Question

Quizplus · Accepted Answer

Sigh breaths are additional breaths given at a higher volume than the regular ventilatory cycle to prevent or treat atelectasis (collapse of part of the lung). They are not specifically indicated for patients with stiff lungs, as in choice C, because in such cases, the primary concern is avoiding lung injury from overdistension, and sigh breaths could potentially exacerbate this by delivering higher volumes to already compromised lung tissue. Choices A, B, and D are situations where sigh breaths might be used to improve lung compliance and oxygenation or to counteract the effects of using small tidal volumes, which can lead to atelectasis.
