The endothelium synthesizes and releases a relaxing factor with the physiochemical properties of nitric oxide (NO). However, the role of endothelium-derived NO in the basal regulation of systemic and pulmonary vascular resistance in humans is not known. Our primary objectives were to determine the effects of inhibiting NO synthesis on blood pressure and systemic vascular resistance and to establish the role of endothelium-derived NO in the regulation of normoxic pulmonary vascular tone.
