Clinical observation of noninvasive positive pressure ventilation in 72 patients with acute cardiac pulmonary edema

Objective:To study the effects on the treatment of acute cardiogenic pulmonary edema with noninvasive positive pressure ventilation. Methods:72 patients with acute cardiogenic pulmonary edema were divided into two groups according to retention of carbon dioxide,the PCO245 mm Hg and PCO245 mm Hg group,and then each group was randomly divided into NPPV group (n=18) and control group (n=18). Results:The respiratory rate,heart rate,oxygen satura- tion and the rate of endotracheal intubation were significantly improved in the PCO245 mm Hg group with noninvasive positive pressure ventilation and the mortality also has decreasing trend (P0.05),but in the PCO245 mm Hg group,the difference was not remarkable. Conclusion:The effect would be better when patients have retention of carbon dioxide on the treatment of acute cardiogenic pulmonary edema with noninvasive positive pressure ventilation.
