目的观察双水平气道正压(BiPAP)呼吸机治疗慢性阻塞性肺疾病合并II型呼吸衰竭的疗效。方法用BiPAP呼吸机经鼻(面)罩正压辅助通气治疗37例慢性阻塞性肺疾病(COPD)合并II型呼吸衰竭作为观察组;同期,以鼻导管吸氧治疗33例达同样诊断标准的患者作为对照组。结果经观察:2组患者PaO2、SaO2均有上升,但观察组上升更高更快;观察组治疗前后PaCO2下降差异有非常显著性(P<0.01),对照组治疗前后PaCO2下降不显著(P>0.05)。观察组住院时间明显少于对照组(P<0.01)。结论BiPAP呼吸机容易操作,对COPD合并II型呼衰疗效肯定,可升高PaO2,明显降低PaCO2,减轻症状,为治疗、抢救COPD有效方法。
Objective To observe the curative effect of bi-level positive airway pressure (BiPAP) ventilator on chronic obstructive pulmonary disease with type II respiratory failure. Methods 37 patients with chronic obstructive pulmonary disease (COPD) and type II respiratory failure were treated with BiPAP ventilator nasal (facial) mask positive pressure assisted ventilation as the observation group. During the same period, nasal catheter oxygen therapy for 33 patients with the same diagnostic criteria Patients served as control group. The results were observed: the PaO2 and SaO2 in both groups increased, but the observation group increased more rapidly; PaCO2 decreased significantly in the observation group before and after treatment (P <0.01), PaCO2 did not decrease significantly in the control group before and after treatment (P > 0.05). The hospitalization time of the observation group was significantly less than that of the control group (P <0.01). Conclusions The BiPAP ventilator is easy to operate and affirmed COPD with type II respiratory failure. It can increase PaO2, reduce PaCO2 and relieve symptoms effectively. It is an effective method for the treatment and rescue of COPD.
