目的探讨无创通气在治疗慢性阻塞性肺疾病(COPD)并呼吸衰竭的有效性和安全性。方法对20例慢性阻塞性肺疾病(COPD)并Ⅱ型呼吸衰竭患者采用BiPAP呼吸机经口鼻面罩正压通气,观察治疗前后血气分析的PH、PaO2、PaCO2、SaO2指标变化判断疗效。结果无创通气后氧分压,二氧化碳分压均明显升高,PaCO2明显降低、PH改善、统计学存在显著性差异。结论无创通气可以改善COPD并呼吸衰竭患者生命指征和动脉血气指标,减轻呼吸肌疲劳,减少气管插管率。
Objective To investigate the efficacy and safety of non-invasive ventilation in the treatment of chronic obstructive pulmonary disease (COPD) and respiratory failure. Methods 20 patients with chronic obstructive pulmonary disease (COPD) and type Ⅱ respiratory failure were treated with BiPAP ventilator with positive pressure ventilation of nose and mouth mask. The changes of PH, PaO2, PaCO2 and SaO2 in blood gas analysis before and after treatment were observed. Results Non-invasive ventilation oxygen partial pressure, partial pressure of carbon dioxide were significantly increased, PaCO2 decreased significantly, PH improved, statistically significant difference. Conclusion Noninvasive ventilation can improve the vital signs and arterial blood gas indexes in patients with COPD and respiratory failure, reduce respiratory muscle fatigue and reduce the rate of endotracheal intubation.
