目的观察早期长时间应用无创机械通气对COPD急性加重合并Ⅱ型呼吸衰竭患者的影响。方法选取早期长时间应用无创呼吸机治疗的COPD急性加重期合并呼吸衰竭患者37例,与短时间使用无创机械通气的患者37例做生命体征、动脉血气、血氧饱和度及平均住院日的比较。结果治疗组血氧状态明显优于对照组,血氧饱和度明显高于对照组,平均住院日较对照组明显缩短,P<0.05,差异有统计学意义。结论早期无创机械通气治疗能显著改善患者血氧状态,缩短患者住院日,值得临床推广应用。
Objective To observe the effect of early noninvasive mechanical ventilation on patients with acute exacerbation of COPD and type Ⅱ respiratory failure. Methods A total of 37 patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and non-invasive ventilator treated with long-term non-invasive ventilator were enrolled in this study. Compared with 37 patients with noninvasive mechanical ventilation for 37 days, the vital signs, arterial blood gas, oxygen saturation and average length of stay were compared . Results The blood oxygen level of the treatment group was significantly better than that of the control group, and the oxygen saturation was significantly higher than that of the control group. The average length of stay was significantly shorter than that of the control group (P <0.05). The difference was statistically significant. Conclusion Early noninvasive mechanical ventilation can significantly improve the patient’s blood oxygen status, shorten the hospitalization days, is worthy of clinical promotion and application.
