目的 探讨无创双水平正压通气(BiPAP)对重症心源性肺水肿所致呼吸衰竭的治疗效果。方法 24例重症心源性肺水肿患者用常规抗心衰治疗无效的情况下,均应用BiPAP治疗2h后,观察其治疗效果。结果 应用BiPAP治疗后氧合情况与治疗前相比较有明显改善。结论 早期应用无创正压通气对改善心源性肺水肿的氧合是有效的。
Objective To investigate the therapeutic effect of noninvasive bi-level positive pressure ventilation (BiPAP) on respiratory failure caused by severe cardiogenic pulmonary edema. Methods Twenty-four patients with severe cardiogenic pulmonary edema were treated with BiPAP for 2 hours after treatment with conventional anti-heart failure, and the therapeutic effect was observed. Results Oxygenation after treatment with BiPAP was significantly improved compared with that before treatment. Conclusion Early application of noninvasive positive pressure ventilation is effective in improving oxygenation of cardiogenic pulmonary edema.
