pulse volume recording
Non-invasive test measuring blood volume changes in limbs to assess arterial circulation.
Full Definition
Pulse volume recording (PVR) is a non-invasive diagnostic technique that uses pneumatic cuffs and plethysmography to measure volume changes in blood vessels during each cardiac cycle. This test provides valuable information about arterial flow patterns, vessel compliance, and the presence of arterial occlusive disease. In vascular medicine reports, PVR results are typically presented as waveform tracings with specific morphological characteristics that indicate the severity and location of arterial disease, requiring careful editorial attention to technical accuracy.
Usage
Usage note: Commonly abbreviated as PVR; ensure distinction from other medical abbreviations in context.
In Context
- "Pulse volume recording demonstrated dampened waveforms in the right lower extremity." — Vascular laboratory report
- "PVR findings were consistent with multilevel arterial disease affecting both superficial and deep circulation." — Diagnostic study interpretation
