Applications
Ankle Brachial Pressure Index – ABPI
The measurement of Ankle Brachial Pressure Index (ABPI) is a useful, non-invasive test performed during investigations of vascular function and has long been used to aid detection and diagnosis of peripheral arterial disease (PAD). Deriving the Ankle Brachial Pressure Index (ABPI), by dividing the systolic blood pressure at the ankle by the systolic blood pressures in the arm is relatively simple to perform and is widely used. Some patients presenting with PAD are asymptomatic, and an abnormal Ankle Brachial Pressure Index (ABPI) is the first indication of the presence of disease. Calculation of the ABPI is also used in some studies to classify patients with peripheral arterial occlusive disease. Ankle Brachial Pressure Index (ABPI) is known to be unreliable on patients with arterial calcification which results in less or incompressible arteries, as the stiff arteries produce falsely elevated ankle pressure. This is often found in patients with diabetes mellitus. 41% of patients with PAD have diabetes, renal failure, or are heavy smokers.
Equipment Recommendations
We recommend the moorLAB-PC software to streamline the measurement and analysis together with a single or dual channel moorLAB-LDF monitor and multi-fibre skin probes (LP1T/7). The CUFF-ARM (or CUFF-ARM-RD) can be used on the ankle and forearm, although a full range is available to accommodate a range of limb sizes. The moorLAB-PRES provides automation of the cuff inflation / deflation protocol.
