Summary

NICE guidelines recommend an Ankle brachial pressure index (ABPI) as the primary assessment tool for patients presenting with symptoms or are at a high risk of developing peripheral arterial disease (PAD). An ABPI is typically performed using a hand-held Doppler to listen and classify the arterial signal in the ankle and arm and the systolic pressure is taken in each to create a ratio of the pressure in the ankle to the arm. New Huntleigh Dopplex DMX Digital Dopplers within the vascular department have an arterial waveform display to help interpretation of the audible signal.

This study aims to compare the audible and visual waveform traces on the Huntleigh Dopplex with the gold standard of ultrasound duplex to assess the accuracy of the trace using diagnostic measurements and the ability of clinicians to correctly identify audible and visual waveforms.
