无创机械通气治疗COPD合并Ⅱ型呼吸衰竭疗效观察

Effectiveness of bilevel positive airway pressure ventilation in COPD complicated with type respiratory failure

对42例符合COPD合并Ⅱ型呼衰随机分组进行对照分析。经无创机械通气治疗的21例患者呼吸频率、心率、PaCO2均有明显下降。无创机械通气治疗COPD合并Ⅱ型呼衰疗效肯定,是值得推广的一种治疗方法。

Objective To investigate the effectiveness of treatment with bilevel continuous airway pressure（BiPAP） ventilation on chronic obstructive pulmonary disease（COPD） complicated with typeⅡ respiratory failure.Methods Treatment effects were compared between the two groups into which 42 patients with COPD complicated with type Ⅱ respiratory failure were randomly classified.Results Respiration,heart rate and PaO2 were significantly decreased after treatment in 21 patients with bilevel positive air way pressure.Conclusion BiPAP is effective to treat patients with COPD complicated with typeⅡ respiratory failure.It deserves to become a popular treatment method.
