随着对呼吸和循环生理的不断深入研究和呼吸治疗设备的改进 ,近年来无创正压通气 (NPPV)用于治疗急性肺水肿 (APE)的情况不断增多 ,研究结果表明NPPV不仅可以改善APE患者的肺水肿和气体交换 ,同时能改善心功能 ,这与传统观念有较大差异 With the continuous research on respiratory and circulatory physiology and the improvement of respiratory therapy equipment, the use of noninvasive positive pressure ventilation (NPPV) in the treatment of acute pulmonary edema (APE) has been increasing in recent years. The results show that NPPV can not only improve APE patients Of pulmonary edema and gas exchange, while improving heart function, which is quite different from the traditional concept
