Pulse Volume Recording (PVR)
Pulse Volume Recording (PVR) is a noninvasive vascular test that uses blood-pressure cuffs to measure changes in limb volume with each pulse, helping detect and localize peripheral arterial disease without imaging contrast.
What is Pulse Volume Recording (PVR)?
Pulse Volume Recording (PVR) is a noninvasive vascular test that uses inflatable blood-pressure cuffs placed at different levels of a limb to detect the small changes in volume that occur with each heartbeat. The waveforms it produces reflect how well blood is flowing through the arteries at each point.
Because PVR relies on pressure cuffs rather than imaging dye, it can assess circulation without contrast agents or radiation. Comparing waveforms along the leg or arm helps clinicians see where blood flow is reduced.
Why is PVR clinically useful?
PVR is valuable for detecting and localizing peripheral arterial disease, helping clinicians judge the severity and approximate location of arterial narrowing. This guides decisions about further imaging, medical management, or intervention.
As a low-risk, equipment-light test, PVR fits well into outpatient vascular evaluation. It is often performed alongside other noninvasive studies to build a complete picture of a patient's circulation before any procedure is considered.
