近年来推出一些非创伤性处理方法,以取代气管造口间歇正压通气术(TIPPV),已引起医学界广泛兴趣,其中包括口腔间歇正压通气(MIPPV)和鼻腔间歇正压通气(NIPPV)。作者旨在确定肺活量(VC)减低的病人,在不用氧气的情况下接受夜间NIPPV 治疗,是否能够缓解慢性肺泡换气不足(CAH)的症状,使睡眠时的氧饱和度(SaO_2) In recent years, a number of non-invasive treatment methods have been introduced to replace TIPPV, which have attracted widespread medical attention. Among them, MIPPV and NIPPV (Nasal Interval Positive Pressure Ventilation) . The aim of the authors was to determine if patients with reduced vital capacity (VC) who underwent nIPPV without oxygen at night were able to relieve the symptoms of chronic alveolar hypoventilation (CAH) and the oxygen saturation during sleep (SaO 2)
