左心衰所致的急性肺水肿是一种主要表现为呼吸窘迫和低氧血症的危症,治疗的关键在于迅速降低肺毛细血管楔压。 硝酸酯类是静脉扩张剂,主要减少前负荷,降低左室充盈压,同时使血管阻力下降,增加心输出量。在治疗急性左心衰方
Acute pulmonary edema caused by left heart failure is a major manifestation of respiratory distress and hypoxemia crisis, the key to treatment is rapid reduction of pulmonary capillary wedge pressure. Nitrates are intravenous dilators, mainly to reduce the preload, reduce left ventricular filling pressure, while reducing vascular resistance, increased cardiac output. In the treatment of acute left heart failure side
