A new international study, led by Dr. Sonny Dhanani of the CHEO Research Institute, and published in the January 28 issue of the New England Journal of Medicine, documents the physiology of the dying process. Working closely with the Canadian Donation and Transplantation Research Program, the research team asked over 600 families to allow their loved ones in the ICU to have their vital signs monitored during the dying process. This is the largest international study of its kind.
