目的探讨应用BiPAP无创机械通气治疗慢性阻塞性肺疾病(COPD)合并呼吸衰竭的疗效。方法对52例COPD合并呼吸衰竭昏迷患者应用BiPAP呼吸机,4h/次,2～3次/d,记录治疗前后生命体征、动脉血气分析变化。结果治疗后PaO2、SpO2和pH升高,PaCO2下降,HR和RR下降,差异均有统计学意义。结论BiPAP无创机械通气对COPD合并呼吸衰竭的治疗较好,疗效确切、可靠。
Objective To investigate the curative effect of BiPAP non-invasive mechanical ventilation on chronic obstructive pulmonary disease (COPD) combined with respiratory failure. Methods BiPAP ventilator was used in 52 COPD patients with respiratory failure coma, 4h / time and 2 ~ 3 times / d, and the changes of vital signs and arterial blood gases were recorded before and after treatment. Results After treatment PaO2, SpO2 and pH increased, PaCO2 decreased, HR and RR decreased, the differences were statistically significant. Conclusions BiPAP noninvasive mechanical ventilation is superior in the treatment of COPD with respiratory failure. The curative effect is accurate and reliable.
