Abstract: A system and method for taking non-invasive blood pressure and other vascular parameter measurements includes placing a vascular compression device about an appendage of a subject. An arterial/venous occlusion cuff is placed about a base of the appendage. The vascular compression device is activated to generate compression ischemia in the appendage. The arterial/venous occlusion cuff is pressurized to generate arterial/venous occlusion in the appendage. The vascular compression device is deactivated. The arterial/venous occlusion cuff is gradually depressurized to allow blood and other body fluids to flow into the appendage and thereupon determine vascular parameters such as, for example, systolic arterial blood pressure, diastolic arterial blood pressure, venous blood pressure, arterial blood flow, blood vessel compliance, and appendage blood volume.
