Although the technicalities of EMS DNR orders vary, they all:

The primary purpose of EMS Do Not Resuscitate (DNR) orders is to provide clear guidance to emergency medical services regarding the patient's wishes concerning resuscitation efforts. These orders are intended to communicate whether or not EMS providers should perform resuscitation measures in emergencies, ensuring that the care provided aligns with the patient's preferences. By having a standardized way of indicating the patient's wishes, DNR orders help prevent unnecessary interventions when the patient has expressed a desire for comfort rather than aggressive life-saving measures.

The technicalities surrounding DNR orders can indeed differ from one jurisdiction to another; however, the core intent remains consistent: to respect the patient's wishes regarding resuscitation. This encompasses a variety of situations and allows patients to make informed choices about their medical care, particularly in end-of-life scenarios.
