"Do Not Resuscitate" (DNR) is a medical order that indicates a patient's wishes not to receive cardiopulmonary resuscitation (CPR) or advanced cardiac life support in the event of cardiac or respiratory arrest. This decision is typically made by patients, or their healthcare proxies, after careful consideration of their health status and end-of-life preferences. DNR orders are intended to respect the patient's autonomy and ensure they receive care aligned with their values and wishes. It's important for patients to discuss their choices with healthcare providers to fully understand the implications.
