Who writes out DNR forms?

A do-not-resuscitate form is written by a medical doctor, according to MedlinePlus. Before writing out the form, the doctor must consult with the patient's proxy, relatives or possibly the patient himself to ensure that what the written content reflects the patient's wish.

A DNR form is a form that contains the patient's wish not to undergo cardiopulmonary resuscitation in case he stops breathing or his heartbeat stalls, explains MedlinePlus. Typically, the patient makes the wish when he realizes that his condition cannot get better or if he is about to die. However, he reserves the right to reverse his decision and seek to have CPR.
