本文研究慢性阻塞性肺病(COPD)患者接受压缩空气或氧气后的睡眠变化,以便探讨吸氧是否可以改善睡眠质量.患者23例,男14,女9例,年龄42～74岁,平均FEV_1 0、81(SD 0.32)L,平均FEV_1/FVC30%(SD 12%).在睡眠实验室中对17例患者连续2夜进行睡眠研究;另6例连续进行3夜的研究,其中1夜为患者适应环境。以随机交叉双盲法由鼻管接受压缩空气或氧气。吸压缩空气时夜间气流量保持在1 L/min;吸氧时夜间气流量最初为0.5L/min,每10分钟可增加0.5L/min,直至使SaO_2维持在90%以上。以询问
In this paper, we study the changes of sleep in patients with chronic obstructive pulmonary disease (COPD) after receiving compressed air or oxygen in order to explore whether oxygen can improve the quality of sleep.There are 23 patients, 14 males and 9 females, aged from 42 to 74 years with an average FEV 1 0 , 81 (SD 0.32) L, and mean FEV 1 / FVC 30% (SD 12%). Seventeen patients in the sleep laboratory performed sleep studies for two consecutive nights and six in three consecutive nights, including one night for patients Adapt to the environment. Compressed air or oxygen was received by the nasal cannula in a randomized double-blind method. Suction compressed air at night when the air flow was maintained at 1 L / min; oxygen flow at night when the night was 0.5L / min initially, every 10 minutes to increase 0.5L / min, until the SaO_2 maintained at 90%.
