Pulse Volume Recording and Vascular Studies
Pulse Volume Recording (PVR) Waveform Analysis
To assess blood flow in the limbs, pulse volume recordings (PVRs) may be performed. Blood pressure cuffs are inflated on the limb and blood pressure in the limb is measured, which uses the Doppler transducer. This is a technique used to calculate blood volume changes in the legs using a recording device that displays the results as a waveform.
