In a medical context, what does "do not resuscitate" (DNR) specifically refer to?

The term "do not resuscitate" (DNR) specifically refers to an order not to perform cardiopulmonary resuscitation (CPR) on a patient in the event of cardiac arrest or respiratory failure. DNR orders are established to respect a patient's wishes, particularly when they have a terminal illness or when resuscitation would not improve their quality of life. This allows healthcare providers to honor the patient's decision regarding end-of-life care, ensuring they are not subjected to invasive procedures that they have chosen to forgo.

The concept of a DNR is primarily focused on the immediate actions taken in emergencies, such as the initiation of CPR or advanced life support measures. It's crucial for EMTs and other medical professionals to recognize and follow DNR orders to provide appropriate care that aligns with the patient's values and choices regarding their health and treatment options.
