The hypertension associated with acute pulmonary edema is usually a result of increased peripheral vascular resistance caused by elevated catecholamines. In some cases, pulmonary edema occurs because an abrupt rise in blood pressure precipitates acute left ventricular failure. The blood pressure must be lowered to reverse this process, and nitroprusside and intravenous nitroglycerin are the agents of choice, although the latter does not reduce blood pressure as much as nitroprusside. Additional standard therapy for pulmonary edema includes nitrates (to reduce preload and afterload), oxygen, diuretics, and morphine sulfate.
