Which condition is CPAP typically used to treat when oxygen alone is not sufficient?

CPAP provides a constant positive pressure to keep the airways open throughout the breathing cycle. In acute pulmonary edema, fluid fills the alveoli and interstitial spaces, causing alveolar collapse and poor oxygen exchange. By stenting open more of the collapsed airways, CPAP improves alveolar recruitment, increases the surface area for oxygen transfer, and reduces the work of breathing. The result is better oxygenation when oxygen alone isn’t enough. The increased intrathoracic pressure also helps decrease pulmonary congestion, easing edema in the lungs. This approach is not used for a pneumothorax, where positive pressure can worsen the air leak, and while CPAP can be used in some respiratory conditions, its classic use in this scenario is to treat edema-related hypoxemia.
