目的探讨无创正压通气在治疗急性左心衰竭的疗效及临床价值。方法对40例急性左心衰竭患者在常规治疗基础上实施无创正压通气,观察通气前后动脉血气分析、呼吸频率、心率、血压及临床症状等指标改善情况。结果 40例患者经无创正压通气后,呼吸、心率、血压、动脉氧饱和度、氧分压水平均优于治疗前,差异有统计学意义(P<0.05)。结论在常规药物治疗的同时,使用无创正压通气,可较快纠正患者缺氧状态,改善呼吸功能,有助于缩短病程,降低病死率,具有较好的临床应用价值,值得推广。
Objective To investigate the curative effect and clinical value of non-invasive positive pressure ventilation in the treatment of acute left heart failure. Methods 40 cases of patients with acute left heart failure were treated with noninvasive positive pressure ventilation on the basis of conventional treatment. The improvement of arterial blood gas analysis, respiratory rate, heart rate, blood pressure and clinical symptoms before and after ventilation were observed. Results After 40 cases of non-invasive positive pressure ventilation, respiration, heart rate, blood pressure, arterial oxygen saturation and oxygen partial pressure were better than those before treatment (P <0.05). Conclusions The conventional non-invasive positive pressure ventilation can correct the hypoxia state and improve the respiratory function of patients, which will help to shorten the course of disease and reduce the mortality rate. It is worth to be popularized.
