Two nights PSG results, including sleep architecture, breathing events, oxygen desaturation and arousal were compared. Results With the CPAP treatment, stage 1 sleep was decreased, while stage 3+4 sleep and the REM sleep were significantly increased, also arousals, respiratory events and the degree of oxygen desaturation were significantly decreased.

结果 CPAP治疗后，各项指标较治疗前明显好转，患者睡眠结构趋于正常，1期浅睡眠减少，3+4期深睡眠及REM期睡眠明显增加；微觉醒、呼吸事件和血氧饱和度下降幅度明显减少；轻、中、重度OSAHS患者各项指标变化有一定差异。

Methods: Twenty ASA Ⅱ~Ⅲ patients aged 28~69 years were randomly divided into 2 groups:(1)3-mins group (n=10).(2)8 deep breathings group (8DB). Arterial blood samples were drawn with a fraction of inspired oxygen of 0.21for arterial blood gas analysis. Before induction of anesthesia, patients in 3 mills group were asked to breathe normally for 3 mins during which 100% oxygen at 10 L/min through an anesthesia mask attached to a circle system with soda lime was adopted, and adjustable pressure limiting valve was kept open.

20例气管插管患者随机分为吸氧去氮组（3MIN组）与60s深呼吸8次组（8DB组），入手术室后在呼吸空气情况下采集动脉血气标本测定血气分析，并记录SpO2值。3MIN组采用完全密闭面罩，氧流量10L，麻醉机活瓣旋开以15次／min频率自然呼吸3min.8DB组在相同条件下在60s内深呼吸8次。
