Dr. Hillary Lum, an associate professor of medicine at the University of Colorado School of Medicine, said people should make decisions based on their perception of the quality of life. “The questions about a do not resuscitate order are emotional and important to have accurate information,” Lum said. “Thinking about whether someone wants a do-not-resuscitate or not should be related to what is the likelihood of that procedure being beneficial to a person who restarts their heart and lungs but also return to a life that they value.”
