[摘要] 目的：探讨双水平正压通气(BiPAP)呼吸机对慢性Ⅱ型呼吸衰竭的临床治疗应用价值。方法：将74例慢性Ⅱ型呼吸衰竭患者随机分为BiPAP呼吸机治疗组(39例)和常规治疗对照组(35例)。对照组给予常规治疗，治疗组除常规治疗外，加双水平正压通气(BiPAP)治疗，并监测其治疗前后的血气和呼吸频率、心率的变化，对结果进行统计学处理。结果：治疗后6 h，治疗组动脉血氧分压(PaO2)的明显升高，动脉血CO2分压(PaCO2)明显下降，与治疗前比较，差异有统计学意义(P<0.05)；对照组PaO2和PaCO2的变化和与治疗前比较，差异无统计学意义(P>0.05)。结论：应用BiPAP呼吸机治疗慢性Ⅱ型呼吸衰竭安全、有效，具有较高的临床治疗应用价值。

[Abstract] Objective: To investigate the effect of bi-level positive airway pressure (BiPAP) ventilator in the treatment of typeⅡ chronic respiratory failure. Methods: 74 cases of typeⅡ chronic respiratory failure were randomly divided into BiPAP ventilator treatment group(39 cases,treatment group) and conventional treatment group (35 cases,control group). Patients of control group accepted conventional treatment; in addition to conventional treatment, BiPAP treatment was applied in treatment group,and monitored the blood gas and respiratory rate, heart rate changes of two groups before and after treatment. Results: 6 h after treatment, PaO2 in treatment group significantly increased, PaCO2 decreased significantly, compared with them before treatment, there was a significant difference(P<0.05); PaO2 and PaCO2 of control group had no significant difference before and after treatment (P>0.05). Conclusion: The application of BiPAP ventilation in the treatment of type Ⅱ chronic respiratory failure is safe and effective, there is a high clinical value.

随着医学的发展，人工呼吸机已成为治疗各种类型呼吸衰竭的重要手段。然而，有创的人工通气需要气管插管或气管切开，给患者带来一定的痛苦和危险，且可引起与呼吸机相关肺炎等并发症及撤机困难等。因此，无创人工通气越来越受到重视，我科2003年以来采用无创性鼻(面)罩双水平气道正压BiPAP(bi-level positive airway pressure)呼吸机治疗慢性Ⅱ型呼吸衰竭，取得了较好的效果，现报道如下：
