Pulse Volume Recording (PVR)
Pulse Volume Recording (PVR) is a non-invasive vascular diagnostic technique that provides precise assessment of blood flow in the limbs. Using blood pressure cuffs, PVR delivers reliable and reproducible results for vascular health assessment, helping clinicians diagnose and monitor peripheral artery disease (PAD) and other vascular conditions.
Pulse Volume Recording (PVR) is a non-invasive vascular test that measures blood pressure and blood flow in the legs using blood pressure cuffs. According to the Cleveland Clinic, PVR tests use ultrasound (high-frequency sound waves) to evaluate circulation in arteries and can help diagnose peripheral artery disease (PAD) and locate blood clots or blockages. A PVR waveform is a graphical representation of blood volume changes in a limb over time, generated during the test.
- Non-invasive and painless for the patient
- Provides both qualitative waveforms and quantitative data
- Essential for diagnosing peripheral arterial disease (PAD) and other vascular conditions
According to the Cleveland Clinic, PVR tests place blood pressure cuffs on the big toes, ankles, calves, upper and lower thighs, and arms. The cuffs are inflated to measure blood pressure, and a handheld transducer applies ultrasound waves to different parts of the leg. The sound waves measure the speed and volume of blood moving through the legs, with results appearing as waveforms on a computer monitor.
- Automated calibration for every channel and test
- High-fidelity pressure measurement for accurate readings
- Real-time waveform display and data export
PVR is invaluable for:
- Detecting and grading peripheral arterial disease (PAD)
- Assessing arterial occlusions and stenosis
- Monitoring post-intervention outcomes
- Evaluating limb perfusion in diabetic and high-risk patients
- Supporting clinical decision-making with objective, reproducible data
PVR is endorsed by major vascular and cardiovascular societies as an essential component of comprehensive vascular assessment.
