目的探讨双水平正压无创通气(B iPAP)对慢性阻塞性肺病(COPD)患者合并Ⅱ型呼吸衰竭的治疗价值。方法对32例慢性阻塞性肺病(COPD)并II型呼吸衰竭患者给予B iPAP呼吸机通气治疗,观察治疗前后PH、PaO2、PaCO2、SaO2等指标变化。结果B iPAP呼吸机治疗后4h及48h及通气结束后较治疗前PaO2、SaO2均明显升高,PaCO2明显降低(P均<0.05),PH值无明显变化(P>0.05)。治疗后临床症状得到明显改善。结论B iPAP呼吸机对COPD合并Ⅱ型呼吸衰竭疗效显著。
Objective To investigate the therapeutic effect of BipAP on patients with chronic obstructive pulmonary disease (COPD) complicated with respiratory failure. Methods Bipap ventilator ventilation was used in 32 patients with chronic obstructive pulmonary disease (COPD) and type II respiratory failure. The changes of PH, PaO2, PaCO2 and SaO2 before and after treatment were observed. Results Compared with before treatment, the PaO2 and SaO2 were significantly increased and the PaCO2 was significantly decreased at 4h and 48h after ventilation and after ventilation (all P <0.05). There was no significant change in PH value (P> 0.05). After treatment, clinical symptoms have been significantly improved. Conclusion B iPAP ventilator has a significant effect on COPD with type Ⅱ respiratory failure.
