目的探讨老年漫性呼吸衰竭急性加重时的无创伤通气疗法。方法随机将住院患者分为A、B两组。A组单独采用BiPAP经两罩辅助压力支持通气，B组除进行辅助压力支持通气外，同时利用氧气做动力，利用射流式雾化品吸入喘乐宁。结果两组均可使动脉血之分析、肺功能及临床症状得到明显改善，但B组改善程度更为明显（P＜0.05、P＜0．01），改善时间提前．维持时间长，且无心悸，手颤等不良反应。结论喘乐宁经BiPAP吸入完全，可明显改善通气功能，早期应用可减少气管插管及切开的机会。
Objective To investigate the noninvasive ventilation therapy in the elderly with acute aggravating respiratory failure. Methods Patients were randomly divided into A and B groups. In group A, BiPAP alone was used to support ventilation with two-cover auxiliary pressure. In addition to auxiliary pressure-support ventilation, group B was powered by oxygen and jetted inhalation of salbutamol. Results The arterial blood analysis, lung function and clinical symptoms were significantly improved in both groups. However, the improvement in group B was more obvious (P <0.05, P <0.01), and the improvement time was earlier. Maintain a long time, and no heart palpitations, hand tremor and other adverse reactions. Conclusions Verapamil is completely inhaled by BiPAP, which can significantly improve the ventilation function. Early application can reduce the chance of tracheal intubation and incision.
