目的 评价无创性鼻 (面 )罩双水平气道正压 (BiPAP)通气治疗急性肺水肿的疗效。方法 对 2 0例急性肺水肿 (心源性和非心源性 )患者在传统常规治疗同时加用BiPAP。呼吸机经鼻 (面 )罩双水平气道正压通气治疗 ,观察通气前后动脉血气分析中pH、PaO2 、PaCO2 、SaO2 的变化 ,患者HR、RR、SBP、DBP及临床征象的变化。结果 通气治疗后 ,2 0例患者临床症状明显改善 ,血气分析中pH、PaO2 、PaCO2 、SaO2 等参数比较有显著性差异 (P <0 0 5 ) ,避免了气管插管机械通气。结论 无创性BiPAP鼻 (面 )罩通气治疗急性肺水肿 ,能迅速改善患者症状和低氧血症 ,避免气管插管 ,是抢救急性肺水肿的一种安全有效的方法
Objective To evaluate the efficacy of noninvasive bi-level positive airway pressure (BiPAP) ventilation in the treatment of acute pulmonary edema. Methods Twenty 20 patients with acute pulmonary edema (cardiogenic and noncardiogenic) were treated with BiPAP in the conventional treatment. Ventilator was treated by bilevel positive airway pressure (MAP). The changes of pH, PaO2, PaCO2, SaO2, HR, RR, SBP, DBP and clinical signs in arterial blood gas analysis before and after ventilation were observed. Results After ventilation, the clinical symptoms of 20 patients were significantly improved. The parameters of pH, PaO2, PaCO2 and SaO2 in blood gas analysis were significantly different (P <0 05), which avoided the mechanical ventilation of tracheal intubation. Conclusion Noninvasive BiPAP nasal mask ventilation for acute pulmonary edema can rapidly improve symptoms and hypoxemia in patients without tracheal intubation and is a safe and effective method to rescue acute pulmonary edema
