In the evaluation of lower extremity arteries, what does "PVR" stand for?

PVR stands for Pulse Volume Recording, which is a non-invasive vascular test used to assess the function of the lower extremity arteries. This technique measures the changes in blood volume in the limbs during the cardiac cycle, providing insights into arterial health and blood flow.

In Pulse Volume Recording, pressure sensors are used to create a curve that represents the pulse waveforms throughout the ankle and leg. This information assists in diagnosing peripheral artery disease and determining the severity of any vascular pathologies. The PVR test can help identify not only the presence of arterial occlusions but also the characteristics of blood flow, allowing for comprehensive analysis of vascular health.

Understanding this term and its application in vascular studies is crucial for effectively evaluating lower extremity arterial function and health.
