Deciding about Cardiopulmonary Resuscitation (CPR): Do-Not-Resuscitate (DNR) Orders

A Guide for Patients and Families

What do CPR and DNR orders mean?

CPR - cardiopulmonary resuscitation - refers to the medical procedures used to restart a patient's heart and breathing when the patient suffers heart failure. CPR may involve simple efforts such as mouth-to-mouth resuscitation and external chest compression. Advanced CPR may involve electric shock, insertion of a tube to open the patient's airway, injection of medication into the heart and in extreme cases, open chest heart massage.
