为了观察住院慢性阻塞性肺疾病（ＣＯＰＤ）合并睡眠呼吸暂停综合征（重叠综合征）的发生并探讨其诊治方法，对２５例住院ＣＯＰＤ病人依多导睡眠图检查分为单纯ＣＯＰＤ组和重叠综合征组，分别在鼻管吸氧、吸氧＋经鼻罩双水平气道内正压（ｎＢｉＰＡＰ）通气、吸氧＋经鼻罩持续气道内正压通气（ｎＣＰＡＰ）治疗下观察两组治疗效果及耐受性。结果２５例中１０例为重叠综合征。其夜间低氧较单纯ＣＯＰＤ组更严重，吸氧可改善夜间低氧，但可加重夜间呼吸紊乱。吸氧＋ｎＢｉＰＡＰ通气治疗可改善夜间低氧和呼吸紊乱。吸氧＋ｎＣＰＡＰ治疗多数不能耐受。本组住院ＣＯＰＤ者重叠综合征的发生率约４０％，对ＣＯＰＤ伴夜间打鼾或白天嗜睡者，应作多导睡眠图检查，吸氧＋ｎＢｉＰＡＰ通气可作为重叠综合征首选治疗方法
In order to observe the incidence of COPD with sleep apnea syndrome (OVX) and to explore its diagnosis and treatment, 25 patients with COPD were divided into simple COPD group and overlapping group according to polysomnography In the levitation group, nBiPAP ventilation and oxygen inhalation + nasal mask continuous positive airway pressure (nCPAP) Group treatment effect and tolerance. Results of 25 cases, 10 cases of overlap syndrome. The night of hypoxia more serious than the simple COPD group, oxygen can improve nighttime hypoxia, but may aggravate nighttime breathing disorders. Oxygen + n PiPAP ventilation can improve nighttime hypoxemia and respiratory disorders. Oxygen + CPCP treatment can not tolerate the majority. The incidence of hospitalized patients with COPD overlap syndrome about 40% of COPD with nighttime snoring or daytime sleepiness should be polysomnography, oxygen + nBiPAP ventilation can be used as the preferred treatment of overlapping syndrome
