목적: In sixteen randomized controlled trials, autotitrating continuous positive airway pressure (autoPAP) were able to reduce the apnea hypopnea index (AHI) to less thean 1- events/hour in 80-95% of patients studied. Consequently, there has been increasing interest in the use of simplified, ambulatory models of care involving clinical prediction tools, portable sleep monitoring and home autoPAP. 방법: The records of 38 consecutive snoring patients ( 24 males, 14 females) diagnosed with Obstructive sleep apnea (OSA) (apnea-hypopnea index AHI 15) were retrospectively reviewed. We excluded subjects with a sleep efficiency <40% or an apnea-hypopnea index (AHI) <15. AutoPAP (RemStar auto, Philips Respironics) parameters were reported. 결과:The 38 patients were prescribed the autoPAP. 7 patients were used only 10 to 20 days. Others (81.57%) were used over 30 days. The patients were obese (BMI 25.62 3.87 kg/m2). The initial mean AHI and lowest O2 saturation were 39.60 25.09 and 74.06 9.05. Mean AHI in using autoPAP were 4.88 4.16. The acceptance of autoPAP therapy was 79.04 21.30 (%). The autoPAP adherence as percentage of nights used at least 4 hr was 53.5128.53 (%). The mean optimal fixed pressure in autoPAP was 7.191.34 cmH2O. 결론:AutoPAP treatment was have been successfully incorporated into ambulatory management. Our results suggested that autoPAP devices are proper management for OSA patients in terms of acceptance, adherence, and AHI improvements.
