Comparison of Positional Therapy to CPAP in Patients with Positional Obstructive Sleep Apnea
While treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) therapy has been shown to be clinically effective, compliance is poor, and as a result, alternative therapies often need to be considered. With the recognition that many patients with OSA have positional OSA, where the majority of sleep-disordered breathing events occur in the supine position, prospective studies comparing positional therapy to CPAP therapy in these patients have been performed. The results of these short-term studies, both in regard to sleep-disordered breathing and sleep quality, suggest that positional therapy as a primary treatment can be as effective as CPAP therapy in patients with positional OSA and in those patients who are intolerant to CPAP therapy. More long-term trials that prospectively and quantitatively compare effectiveness and compliance between positional therapy and CPAP therapy appear warranted.
