E)it improves alveolar fluid distribution

Question

Quizplus · Accepted Answer

CPAP (Continuous Positive Airway Pressure) does not directly increase FEV1 (Forced Expiratory Volume in 1 second), which is a measure of how much air a person can forcefully exhale in one second. It is primarily used to keep the airways open, recruit collapsed alveoli, prevent alveolar collapse, improve functional residual capacity (FRC), and can help in improving alveolar fluid distribution, but it does not directly affect the FEV1, which is more related to airway obstruction and airflow limitation.
