Accuracy of an Unattended Home CPAP Titration in the Treatment of Obstructive Sleep Apnea

摘要

Treatment of sleep apnea - hypopnea syndrome (SAHS) by fixed continuous positive airway pressure (CPAP) requires an in-labora - tory titration procedure to determine the effective pressure level (Peff). We recently reported that one auto-CAP machine can be used without titration study allowing Peff determination. The aim of this study was to evaluate the accuracy of an auto CPAP trial at home. A 1-or 2-wk automatic CPAP trial was done at home in 40 patients by estimating the reference pressure (Pref) to be set and a Pref + 3 cm H_2O/-4 cm H_2O pressure interval.
