目的 :了解 Bi PAP呼吸机对治疗 COPD并 型呼衰患者的疗效。方法 :将 COPD并 型呼衰患者随机分为两组 ,一组予 Bi PAP呼吸机治疗 ,另一组只予一般常规治疗 ,监测其治疗前后血气变化。结果 :经 Bi PAP呼吸机治疗的患者血 Pa CO2 下降幅度较一般治疗组大 ,临床症状改善较显著。结论 :Bi PAP呼吸机对早、中期呼衰治疗疗效肯定 ,早期应用能减少气管插管和气管切开 ,有助于患者的康复。
Objective: To understand the effect of Bi PAP ventilator on patients with COPD and respiratory failure. Methods: Patients with COPD and respiratory failure were randomly divided into two groups. One was treated with Bi PAP ventilator and the other was treated by conventional therapy only. Blood gas changes before and after treatment were monitored. Results: The decrease of PaCO 2 in patients treated with Bi PAP ventilator was larger than that in the general treatment group, and the clinical symptoms improved significantly. Conclusion: Bi PAP ventilator is effective in the treatment of early-to-middle-term respiratory failure. Early application can reduce endotracheal intubation and tracheotomy, which is helpful to patients’ recovery.
