WebNormal Triphasic Doppler waveforms, pressures and ABI’s (shown in brackets) from both legs and normal PVR’s (grade A). Fig 4: Right leg has normal flow, pressure and ABI with normal (grade A) PVR. Left leg has moderate PAD with monophasic Doppler waveform, low pressure and ABI, and poor, low amplitude PVR waveform (Grade D) Fig 5: WebTo 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. greater manchester homelessness network
