A "Do Not Resuscitate" (DNR) order is a legal document that indicates a person's wish not to receive cardiopulmonary resuscitation (CPR) or other life-saving measures in the event of cardiac arrest or respiratory failure. This decision is often made by individuals with terminal illnesses or those who wish to avoid aggressive medical interventions at the end of life. DNR orders are typically discussed between patients, their families, and healthcare providers. It is important for these orders to be clearly documented in medical records to ensure that healthcare professionals respect the patient's wishes during emergencies.
