Pulse Volume Recording (PVR)
What is a pulse volume recording (PVR)?
Pulse volume recording (PVR) is a quick, noninvasive, and painless test designed to measure blood pressure and blood flow in a patient’s legs. It is also known as a segmental pressure test or pulse volume plethysmography.
The PVR test utilizes ultrasound technology to evaluate circulation, identify areas with partially blocked arteries, and diagnose or monitor peripheral artery disease (PAD). It can be performed alongside other tests such as the Ankle-Brachial Index (ABI), arterial duplex ultrasound, or an exercise stress test.
Typically, PVR is administered by sonographers or vascular technologists, although nurses may also conduct the test. During the procedure, a blood pressure cuff is placed on the arms, upper and lower thighs, calves, ankles, and big toes. The cuffs are inflated, and a transducer is used to apply ultrasound waves to various parts of the legs. The resulting data is displayed on a computer screen.
Healthcare providers may use PVR to diagnose PAD, assess its severity, or identify blood clots and other blockages in the legs. It is particularly useful for evaluating patients who experience leg pain while walking.
When may a healthcare provider use pulse volume recording (PVR)?
Pulse volume recording (PVR) is a valuable tool for healthcare providers when diagnosing and evaluating peripheral artery disease (PAD). It helps determine the severity of PAD by assessing blood flow and pressure in the legs.
Additionally, PVR is useful for detecting blood clots or other obstructions in the legs. It is often recommended for patients who experience leg pain during physical activity, as it provides critical information on circulation issues and potential blockages.
