Continuous positive airway pressure (CPAP) therapy effectively reverses sleep-related disordered breathing and daytime symptoms, and mitigates acute pathophysiologic responses such as sympathetic activation and endothelin elevation, though long-term cardiovascular mortality benefits remain unproven.

If you have been diagnosed with Obstructive Sleep Apnea, CPAP is the most effective treatment to stop breathing interruptions and reduce daytime sleepiness. While it may not yet be proven to extend life expectancy in heart failure patients, it significantly improves cardiovascular markers like blood pressure and sympathetic activity. If you struggle with the mask, ask your provider about heated humidification or nasal sprays to improve comfort and adherence.

GoodQualifiesHIGH confidence
Continuous positive airway pressure (CPAP) is very effective at reversing sleep-related disordered breathing events and consequent daytime symptoms... The role of CPAP and other modes of therapy in the management of systemic disease that coexists with obstructive sleep apnea is promising but remains to be determined by rigorous interventional controlled trials.

Why this rating

The paper cites rigorous longitudinal cohort studies for diagnosis and small randomized trials for CPAP effects, but notes a lack of large-scale RCTs for mortality.
