AIM To evaluate the efficacy of artificial controlled mechanical ventilation in the treatment of the patients with severe acute pulmonary edema (APE). METHODS Eighteen patients with APE (cardiogenic and non cardiogenic) were treated with both artificial controlled me chanical ventilation and conventional treatment. The clinical symptoms, arterial blood gas (pH, PaO 2, PaCO 2, SaO 2), and such vital signs as heart rate,respiratory rate and blood pressure pre and post treatment were recorded to evaluate the efficacy of artificial controlled mechanical ventilation on APE. RESULTS After artificial controlled mechanical ventilation, the clinical symptoms of 18 patients were improved significantly, and the clinically monitoring indices above showed a statistically significant difference,compared with those pre controlled mechanical ventilation ( P <0.05). 18 cases all survived successfully. CONCLUSION These results indicate that artificial controlled mechanical ventilation could improve symptoms and hypoxemia in patients with severe APE,and that it is a safe and effective treating method for APE.
