According to the article, a proper discussion needs to happen between the patient and a physician, to make sure what the patient's wishes are. An example I can think of, is I may not want to live the rest of my life with tubes coming out of me, so I may be inclined towards a DNR. However, a DNR could also cover not using the Heimlich maneuver if I happen to be choking on a bite of apple while still in the hospital. In that case, yes, please resuscitate me.
