UIC-2014-003 – Non-Contact Extraction of Human Arterial Pulse Using a Digital Color Camera

This videoplethysmograph (VPG) acquisition and analysis system is a streamlined yet multipurpose vital signs monitoring tool. The presented non-contact cardiovascular and respiratory monitor measures vital signs using digital color video of a patient’s skin. Blood absorbs visible light more than skin in approximately the 500 – 600 nm range. Therefore, variations in blood volume during the cardiac cycle affect the reflectance of light in time with the heartbeat. Hyunjin Kim hkim227@otm.uic.edu 312355-7843
