Using patent-pending technology called Coded Hemodynamic Imaging, University of Waterloo researchers can monitor vital signs and improve the detection and prevention of cardiovascular conditions. The touchless, portable system monitors a patient's blood flow at multiple arterial points simultaneously and without direct contact with the skin.

Multiple pulse points are sent to a computer for continuous monitoring. The CHI technology is ideal for assessing patients with painful burns, highly contagious diseases, or infants in neonatal intensive care whose tiny fingers make traditional monitoring difficult.

"Since the device can also scan multiple patients individually at once and from a distance, consider the potential in mass emergency scenarios or long-term care homes,” said Professor Alexander Wong, of the Faculty of Engineering at Waterloo and Canada Research Chair in Medical Imaging Systems. “This technology provides for a more predictive approach to monitor vitals and the potential for its use is extensive, such as indicating arterial blockages that might otherwise go undetected, or warning older adults who risk falling as a result of getting dizzy when they stand.”
