慢性阻塞性肺病呼吸衰竭的机械通气治疗（附32例分析）

Mechanical ventilation in chronic obstructive pulmonary disease with pulmonary failure:Analysis of 32 cases

对３２例慢性阻塞性肺病（ＣＯＰＤ）引起的呼吸衰竭肺性脑病患者进行机械通气治疗。所有患者均全程监测血氧饱和度，上机及撤机前后共４次进行动脉血气分析，２９例应用压力支持通气（ＰＳＶ）模式。结果：３０例治疗获得成功，患者存活出院，抢救成功率９３．８％（３０／３２）。

2 patients with respiratory failure due to chronic obstructive pulmonary disease (COPD) were treated by mechanical ventilation.Oxygen saturation was monitored during the whole treatment.Four analyses of arterial blood gases were performed prior to and immediately after starting the ventilation,and before and after its withdrawl.In 29 patients,the pressure supported ventilation was employed.The result showed that the treatment was successful in 30 patients who survived and were discharged with a survival rate of 93 8%.Arterial blood gases analyses suggest that mechanical ventilation may markedly increase PaO 2 and decrease PaCO 2.
