Continuous positive airway pressure (CPAP) therapy significantly reduces subjective and objective daytime sleepiness in patients with obstructive sleep apnea (OSA) compared to placebo.
If you have obstructive sleep apnea, using CPAP therapy nightly will significantly reduce your daytime sleepiness compared to doing nothing or using a placebo treatment. This benefit is most pronounced if your sleep apnea is severe. While previous reviews questioned its effectiveness, current evidence from multiple randomized trials confirms CPAP works to improve both how sleepy you feel and objective sleep tests.
Continuous positive airway pressure therapy significantly improves subjective and objective measures of sleepiness in patients with OSA across a diverse range of populations.
