CPAP is indicated for which conditions?

CPAP works by delivering a steady positive pressure during breaths, which keeps the small airways and alveoli open, improves oxygen exchange, and reduces the work of breathing. In CHF with pulmonary edema, the lungs fill with fluid and gas exchange worsens. The positive pressure from CPAP helps push fluid out of the alveoli, keeps them open, and lowers the amount of fluid returning to the heart (preload) while also easing the heart’s workload (afterload). This combination improves oxygenation and makes breathing easier. For drowning victims, the problem is often hypoxemia from alveolar flooding and collapse after aspiration. CPAP can recruit collapsed alveoli and improve oxygenation by maintaining airway pressure, provided the patient is awake, cooperative, and able to protect the airway. It can reduce the effort required to breathe and help with gas exchange in these cases as long as there are no contraindications. Those contraindications include things like the patient unable to protect their airway, altered mental status with vomiting risk, severe hypotension, or facial trauma that prevents a proper mask seal. When these conditions aren’t present, CPAP can be indicated for both CHF with edema and drowning-related respiratory distress.
