The Treatment of Acute Cardiogenic Pulmonary Edema with Noninvasive Bi-level Positive Airway Pressure Ventilation

Objective: To evaluate the effects of noninvasive bi-level positive airway pressure ventilation.Methods: 20 patients with acute cardiogenic pulmonary edema was treated with noninvasive bi-level positive airway pressure ventilation.Clinical symptoms,signs,two-dimersional color Doppler echocardiogram and blood gas analysis were monitored.Results: 18 patients survived with a success rate of 90%.Significant improvements of vital signs,PaO_2 was found(P0.01)4 hours after ventilation.Ejection fraction was improved markedly(P0.01)3 days after ventilation.Conclusion:Noninvasive bi-level positive airway pressure ventilation can decrease the pulmonary edema,elevate PaO_2 and promptly improve heart function.
