A Do-Not-Resuscitate (DNR) order is a document issued by your physician which states that you do not wish to receive life-saving measures such as cardiopulmonary resuscitation (CPR). When a DNR order is properly executed, a health care provider may not perform CPR on you if he/she knows about the order. If the health care provider feels as if he/she cannot abide by the order if you experience cardiac arrest, he/she must transfer you to a facility that will.
Executing a DNR is in no way considered suicide, and withholding CPR from a person who has a DNR order is in no way considered murder. A DNR order will not invalidate a life insurance policy.
