Pulse Volume Recording (PVR)
Pulse volume recording (PVR) can detect the presence of occlusive lesions in limbs or can be used to identify the anatomical location of occlusive lesions, often in combination with segmental pressures. PVR is based on air plethysmography and measures changes in pressure, reflecting the arterial pulsatility. Arterial calcifications do not impact the evaluation of the result, making PVR ideal to combine with ABI for increased reliability in all patients with diabetes or chronic kidney disease.
- Not affected by vessel calcification
- Ideal to combine with ABI
- Can, in many cases, replace segmental pressure
