A patient with chest pressure and a blood pressure of 88/54 mm Hg may be harmed by a medication that would relieve pain in a haemodynamically stable patient. A patient with acute pulmonary oedema and severe hypertension may benefit from a carefully titrated intravenous vasodilator. The drug name alone does not determine the right action. Start with three questions: which vascular bed is being relaxed, what hemodynamic problem is being treated, and is organ perfusion adequate now? Venous dilation mainly changes preload; arteriolar dilation mainly changes afterload; combined or pulmonary vasodilation requires its own monitoring plan. This framework links pharmacology to the bedside findings that change priority: blood pressure, heart rate, chest pain, mental status, urine output, oxygenation, and skin perfusion.
