Which of the following are true about continuous positive airway pressure (CPAP)?
1) It maintains alveoli at greater inflation volumes.
2) It holds airway pressure essentially constant.
3) It provides the pressure gradient needed for ventilation.
4) It has side effects similar to those of positive pressure ventilation.

Question

Quizplus · Accepted Answer

CPAP maintains alveoli at greater inflation volumes and holds airway pressure essentially constant, which helps prevent alveolar collapse. It does not provide a pressure gradient for ventilation; instead, it keeps the airways open. Side effects are similar to those of positive pressure ventilation, including potential for lung injury and discomfort.
