观察30例慢阻肺合并Ⅱ型呼吸衰竭患者,应用BiPAP双水平压力支持通气治疗的效果,其中15例用单向阀,另15例不用单向阀进行机械通气治疗,并以同期同样标准15例患者作为对照组,三组治疗前后均做动脉血气分析,结果显示:单向阀组经通气治疗后有明显改善通气,提高PaO_2而降低PaCO_2作用,而未使用单向阀组仅提高PaO_2而PaCO_2无明显改善。鉴于它的无创性特点,有益于临床推广使用。文中对BiPAP呼吸机的优缺点及注意事项进行了讨论。
To observe the effect of BiPAP bi-level pressure support ventilation in 30 patients with chronic obstructive pulmonary disease and type Ⅱ respiratory failure, 15 patients were treated with one-way valve and the other 15 patients were treated with mechanical ventilation without one-way valve. The same standard 15 The patients as control group, the three groups before and after treatment were done arterial blood gas analysis showed that: one-way valve group after ventilation treatment significantly improved ventilation, increased PaO_2 PaCO_2 reduce the role, but did not use the check valve group only increased PaO_2 PaCO_2 no significant improvement. In view of its non-invasive features, is conducive to clinical promotion and use. The advantages and disadvantages of BiPAP ventilator and precautions are discussed in this paper.
