Effect of Continuous Positive Airway Pressure on Sleep Architectiure in the Sleep Apnea-Hypopnea Syndrome: A randomized Controlled Trial

摘要

There is randomized controlled evidence that patients with sleep apnea-hypopnea syndrome (SAHS) treated with continuous posi- tive airway pressure (CPAP) have improved daytime function and quality of life. " Before-and-after" data indicate that CPAP improves sleep quality, but there is no randomized controlled evidence of this. We tested the hypothesis that CPAP improved sleep quality in patients with SAHS. We also sought correlations between polysom- nographic (PSG) indices and benefit from use of CPAP.
