目的:探讨无创双水平气道正压通气(BiPAP)对顽固性心力衰竭的近期作用。方法:28例顽固性心力衰竭患者,在原有常规治疗基础上进行BiPAP治疗,疗程7 d。观察治疗前后血气分析、心功能参数及运动耐力等指标的变化。结果:28例患者中治疗有效者25例,疗程结束时心功能参数及运动耐力明显改善。结论:BiPAP作为补充治疗手段可明显改善顽固性心力衰竭患者的心功能。
Objective: To investigate the short-term effect of noninvasive bi-level positive airway pressure (BiPAP) on refractory heart failure. Methods: 28 patients with refractory heart failure were treated with BiPAP on the basis of the conventional treatment for 7 days. Blood gas analysis before and after treatment, cardiac function parameters and exercise tolerance and other indicators of change. Results: Among the 28 patients, 25 were effective and the cardiac function parameters and exercise endurance were significantly improved at the end of the course of treatment. Conclusion: BiPAP as a supplementary treatment can significantly improve cardiac function in patients with refractory heart failure.
