目的观察双相正压无创通气对老年慢性阻塞性肺疾病(COPD)合并呼衰及心衰的疗效。方法将60例老年患者随机分为治疗组(间断规律通气组)和对照组(单次通气组),观察治疗前、后动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO2)、pH值、血氧饱和度(SaO2)、心率(HR)、呼吸(R)指标的变化。结果两组通气治疗后1h监测PaO2、SaO2、PaCO2有显著改善。随着治疗时间的延长,治疗组患者PaO2、SaO2的升高及PaCO2的下降明显优于对照组患者。结论间断规律使用双相正压无创通气能明显改善老年COPD合并呼衰和心衰患者的氧合换气功能,快速缓解心力衰竭,疗效明显优于对照组。
Objective To observe the efficacy of biphasic positive pressure noninvasive ventilation on senile chronic obstructive pulmonary disease (COPD) with respiratory failure and heart failure. Methods Sixty elderly patients were randomly divided into treatment group (intermittent ventilation group) and control group (single ventilation group). PaO2 and PaCO2 were observed before and after treatment. pH, blood oxygen saturation (SaO2), heart rate (HR), respiration (R) index changes. Results PaO2, SaO2 and PaCO2 were significantly improved at 1 hour after ventilation in both groups. With the extension of treatment time, PaO2, SaO2 and PaCO2 in the treatment group were significantly better than those in the control group. Conclusion The intermittent regular use of Bipolar Positive Noninvasive Ventilation can significantly improve the oxygenation and ventilation function of elderly COPD patients with respiratory failure and heart failure and relieve heart failure quickly. The curative effect is obviously better than that of the control group.
