Peripheral Arterial Pulse Volume Recordings and Segmental Pressures

Ultilizes obtained arterial waveforms and pressure of the arms and legs to determine if arterial blockage (stenosis) is present. The ankle or wrist pressures are compared to the upper arm pressure in a ratio called the Ankle/Brachial Index (ABI) or Wrist/Brachial Index (WBI) which indicate normal, mild, moderate or severe arterial disease. Severity of arterial disease can manifest in symptoms ranging from leg pain to non-healing ulcers or gangrene.
