Effect of sodium nitroprusside on cardiovascular function and pulmonary shunt in canine oleic acid pulmonary edema.


The authors investigated the acute effects of nitroprusside on intrapulmonary shunt (Qs/Qt), cardiac output, and left ventricular function in dogs with normal lungs, and again after they developed oleic acid pulmonary edema. Before oleic acid, nitroprusside reduced pulmonary capillary wedge pressure (PCWP) and stroke volume, and there were no changes in Qs… (More)
