What does a "DNR" order indicate about a patient's preferences?

A "DNR" order, which stands for "Do Not Resuscitate," clearly expresses a patient's preference regarding medical intervention in the event of cardiac arrest. This indication is that the patient does not want any attempts at resuscitation, which includes interventions such as chest compressions, intubation, or defibrillation. It's an essential document that reflects the patient's wishes to avoid aggressive measures when their heart or breathing stops, thus prioritizing comfort and quality of life over aggressive treatment that may not align with their values or desires.

In contrast, other responses suggest different levels of medical intervention, such as full aggressive treatment or conditional resuscitation, which do not accurately represent the intent of a DNR order. The DNR explicitly signals a decision for no resuscitative measures, reinforcing the patient's autonomy and right to choose their treatment path in critical situations.
