  • Page 71 Smartdop 30EX ® Vascular Testing Instructions PULSE VOLUME RECORDINGS (PVRs) PVRs use pulse volume (pneumoplethysmography) to identify changes in leg blood volume. Rather than temporarily occluding blood flow, the cuffs are only inflated slightly so that blood continues to flow. Blood pulses in the arteries cause the vessels to expand which changes the air volume in the cuff.
