Therapeutic Research

Abstract

Study objectives：To evaluate the adherence in most severe sleep apnea patients using CPAP（continuous positive airway pressure）. The study was concluded at one urban community‒based clinic sleep laboratories. Design：Retrospective study. Patients：Data were collected on 645 OSAS（obstructive sleep apnea syndrome） patients in whom CPAP was novel applied. Intervention：Appropriate CPAP level was titrated to totally diminished oxygen desaturation and apnea under the one night in laboratory（group T, n＝318）. Auto titration CPAP was applied to purpose of early therapeutic intervention（group A, n＝327）. Measurements and results：Group A（84％）had better adherence of CPAP treatment than Group T（73％）in 5 years. Group A had also longer treatment time than Group T in daily usage time. Auto titrating CPAP might have possibility for replacing in laboratory titration of CPAP, but this needs to be further tested in large studies. This strategy also remains as an option in current guidelines of the American Academy of Sleep Medicine.
