无创呼吸机治疗急性心力衰竭疗效观察 　　【摘 要】目的：使用无创呼吸机进行急性左心力衰竭抢救，探究其临床治疗效果。方法：本文通过将30例已确诊急性左心力衰竭患者随机分为15例采取常规治疗的对照组患者和15例采取无创呼吸机治疗的试验组患者。通过比较两组组实验对象的心率、呼吸频率、PH值、血氧饱和度（SpO2）、二氧化碳分压（PaCO2）、动脉血气（PaO2）以及临床症状的改善情况，判断无创呼吸机治疗的疗效。结果：对照组接受治疗后的显效率为26.66%，有效率为40.00%，无效率为33.33%，总有效率为66.67%；试验组接受治疗后的显效率为60.00%，有效率为33.03%，无效率为6.67%，总有效率为93.33%，两组实验对象的总有效率表现为有显著性差异（P0.05）。对比两组急性心力衰竭患者的治疗前后心率、呼吸频率以及动脉压，可以发现，治疗后对照组患者的心率、呼吸频率和动脉压明显高于试验组，表现为有显著性差异（P0.05）；试验组患者治疗前的心率、呼吸频率和动脉压明显低于治疗前，表现为有显著性差异（P0.05）。结论：医护人员使用无创呼吸机进行急性左心力衰竭抢救可以提高临床治疗效果，提高急性心力衰竭患者的治疗有效率，具有普遍推广价值。 　　【关键词】急性心力衰竭；无创呼吸机；临床效果 　　Abstract Objective： To use noninvasive ventilator to rescue acute left heart failure. Methods： 30 patients with acute left heart failure were randomly divided into control group （n = 15） and experimental group （n = 15） treated with non-invasive ventilator. After comparing the heart rate of the two groups， Ph， SPO _ 2， Paco _ 2， Paco _ 2， and the improvement of clinical symptoms were evaluated. Results： the effective rate of non-invasive ventilator in the control group was as follows： 26.66， the effective rate was 40.00g， the ineffective rate was 33.3333 and the total effective rate was 66.67.The effective rate after treatment in the experimental group was 60.000.The effective rate was 33.03g， the ineffective rate was 6.67 and the total effective rate was 93.333.The total effective rate of the two groups was significantly different （P0.05）. Heart rate of patients with acute heart failure before and after treatment， After treatment， the heart rate， respiratory rate and arterial pressure in the control group were significantly higher than those in the experimental group （P0. 05）. The heart rate， respiratory frequency and arterial pressure in the trial group were significantly lower than those before treatment （P0.05）. Conclusion： the treatment of acute left heart failure by non-invasive ventilator can improve the clinical treatment effect. Improving the effective rate of treatment in patients with acute heart failure i
