Dual Channel PPG (Photoplethysmography) and Pressures
C-PVR™ - Calibrated Pulse Volume Recording
The image on the left shows a large discrepancy in cuff volume (right ankle: 90cc / left ankle: 303cc) and the Revo® software indicates this numerically as well as displaying a caution icon ("?" in a purple circle). In this example, the left ankle cuff should be rewrapped.
The image on the right shows the result of proper cuff wrapping: the difference in cuff volumes is now within an acceptable range (right ankle: 90cc / left ankle: 87cc).
C-PVR™ benefits the user by assisting with proper cuff wrap, thereby giving accurate pressures and reproducible diagnostic waveforms.
