Study Notes

Ankle-Brachial Index (ABI) Assessment

The ankle-brachial index (ABI) primarily assesses the blood flow in the lower limbs.
A low ABI indicates peripheral artery disease (PAD), a condition where the arteries supplying blood to the legs and feet are narrowed or blocked.

Importance of ABI

The ABI is a valuable diagnostic tool because it can detect PAD even in its early stages, when symptoms may be minimal.
Early detection of PAD allows for timely intervention, potentially reducing the risk of complications, such as amputations.

Low ABI Indicators

A low ABI can indicate hardening of the arteries (atherosclerosis), blood clots (thrombosis), or inflammation of the arteries.

ABI Function

The primary function of the ABI is to assess the health of the arteries in the lower extremities.

ABI Calculation

The ABI is calculated by dividing the blood pressure in the ankle by the blood pressure in the arm.
