经面罩双水平气道正压通气治疗急性心源性肺水肿的疗效

目的: 探讨经面罩双水平气道正压(BiPAP)通气治疗急性心源性肺水肿的疗效.方法: 38例急性心源性肺水肿患者,在常规药物治疗的基础上,动脉血氧饱和度仍低于95%,采用经面罩BiPAP通气治疗.观察治疗前后动脉血气分析、呼吸频率、血压和心率的变化.结果:经面罩BiPAP通气治疗后,36例患者动脉血气分析、呼吸频率、心率、血压等指标明显改善,2例无效改为气管插管.BiPAP治疗有效率为94.7%.结论:经面罩BiPAP通气治疗可迅速改善急性心源性肺水肿患者的心功能、肺水肿和低氧血症,减少气管插管的发生率.

Bilevel Positive Airway Pressure Ventilation in Acute Cardiogenic Pulmonary Edema

Objective: To investigate the effect of Bilevel positive airway pressure ventilation in acute cardiogenic pulmonary edema who had been unresponsive to medical treatment.Method: 38 patients with acute cardiogenic pulmonary edema received BiPAP ventilation when the conventional therapy was not effective.The arterial blood-gas analysis,breathing rate,arterial blood pressure,heart rate were recorded.Result: The arterial blood-gas analysis,breathing rate,arterial blood pressure,heart rate were found to be significantly improved after BiPAP ventilation by face mask.Only 2 patients deteriorated and needed intubation.The efficacy of BiPAP ventilation is 94.7%.Conclusion: BiPAP ventilation can improve cardiac function,pulmonary edema,hypoxemia and reduces the need for intubation in patients with acute cardiogenic pulmonary edema.
