The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
Segmental blood pressure is used to measure actual limb blood pressure, to assess and locate arterial occlusion. On the legs, pressure is measured at the ankle, below the knee, above the knee, and mid-thigh. On the arm, measurements are taken at the wrist, below the elbow, above the elbow, and mid-upper arm.

Feet are often cold and to make sure measurement is not affected by local vasoconstriction, the patient's feet may be pre-warmed in water or by warm air to a skin temperature of around 30 °C. Measurement is done with the patient lying flat, with feet at heart level, using sphygmomanometry: the big toe is slightly emptied of blood by squeezing ...
The authors defined healthy resting blood pressure as a reading below 130 over 85 millimeters of mercury — a measurement of pressure known as mmHg — pre-high blood pressure as ranging from 130 ...
Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
High blood pressure (stage 2): 140-179 systolic or 90 or higher diastolic. Hypertensive crisis: ... "Check your blood pressure twice daily at home under resting conditions, sitting down for 10 ...
The cold pressor test is a cardiovascular test performed by immersing the hand into an ice water container, usually for one minute, and measuring changes in blood pressure and heart rate. These changes relate to vascular response and pulse excitability. Some research suggests that the outcome of the cold pressor test can help to predict ...
“The study results suggest that if we only rely on the sitting up blood pressure we typically measure, we might miss the folks who have elevated resting blood pressure because there can be that ...
