[目的]探讨无创正压通气联合腹式呼吸治疗COPD并Ⅱ型呼吸衰竭的疗效。[方法]将45例患者在综合治疗的基础上随机分为治疗组和对照组;治疗组采用无创正压通气联合腹式呼吸,对照组采用无创正压通气进行治疗。对患者治疗前、24h后的心率,动脉血pH值、PaO2、PaCO2的变化进行分析比较。[结果]治疗组24h的结果明显优于对照组,比较差异有统计学意义(P﹤0.01)。[结论]无创正压通气联合腹式呼吸治疗COPD并Ⅱ型呼吸衰竭患者,能增加肺泡通气量,有效减慢患者心率、提高PaO2、降低PaCO2缓解缺氧状况,达到改善呼吸困难的目的。
[Objective] To investigate the curative effect of noninvasive positive pressure ventilation and abdominal respiration in treating COPD and type Ⅱ respiratory failure. [Methods] 45 patients were randomly divided into treatment group and control group on the basis of comprehensive treatment. Non-invasive positive pressure ventilation and abdominal respiration were used in the treatment group and non-invasive positive pressure ventilation was used in the control group. The changes of heart rate, arterial blood pH value, PaO2, PaCO2 before and 24 hours after treatment were analyzed and compared. [Result] The result of 24h in treatment group was obviously better than that in control group, the difference was statistically significant (P <0.01). [Conclusion] Noninvasive positive pressure ventilation combined with abdominal respiration in patients with COPD and type Ⅱ respiratory failure can increase alveolar ventilation, effectively reduce heart rate, increase PaO2 and reduce PaCO2 to alleviate the hypoxia so as to improve dyspnea.
