目的:观察西宁地区(海拔2 260m)慢性阻塞性肺疾病(COPD)患者夜间血氧水平变化,并探讨其临床意义。方法:30例患者均进行7小时以上夜间睡眠时血氧的监测及日间动脉血气检查。结果:30例病人均有不同程度的夜间低氧血症。结论:COPD患者睡眠时低氧血症是COPD患者病情进展,病情恶化的主要因素。
Objective: To observe the changes of nocturnal blood oxygenation levels in patients with chronic obstructive pulmonary disease (COPD) in Xining (elevation 260 mm) and to explore its clinical significance. Methods: Thirty patients were monitored for blood oxygen during nighttime sleep for more than 7 hours and daytime arterial blood gas examination. Results: 30 patients had varying degrees of nocturnal hypoxemia. CONCLUSIONS: Hypoxemia during sleep in COPD patients is the main reason for the progression of the disease and the worsening of the disease in COPD patients.
