COMMON TERMINOLOGY
ABI – Ankle Brachial Index – the ratio of the ankle systolic blood pressure
divided by the brachial (arm) systolic blood pressure.
DP – (or DPA) -- Dorsalis Pedis Artery --- the artery on top of the foot. Used in
the ABI exam.
MHz – Megahertz – Millions of cycles per second --the frequency of the sound
transmitted by a vascular probe is measured in megahertz - 8 million cycles per
second, for example.
PAD – Peripheral Artery Disease – Typically atherosclerosis (also known as
hardening of the arteries) in the leg.
PPG – Photoplethysmography –detects the pulse using reflected light from a
small emitter/detector combination.
PT – (or PTA) – Posterior Tibial Artery – artery on the inside of the ankle used
in the ABI exam.
PVD – Peripheral Vascular Disease – Includes venous as well as arterial
disease.
PVR – Pulse Volume Recording – a means of evaluating the condition of the
arteries by looking at a waveform of small changes in cuff pressure caused by
pulses in the arteries under the cuff.
Segmentals – Pressures and PVRs just like the ABI but done in more cuffs on
the leg to assist in localizing the site of any occlusion. The Doppler probe can
remain at the ankle for the pressures.
TBI – Toe Brachial Index – the ratio of the pressure in the toe divided by the
brachial pressure. It is generally measured with a small toe cuff and a PPG
probe
