In the case where a doctor does not attempt CPR on a patient with a DNR order, which ethical principle are they following?

When a doctor does not attempt CPR on a patient with a Do Not Resuscitate (DNR) order, they are primarily adhering to the ethical principle of autonomy. This principle emphasizes the right of individuals to make informed choices about their own medical treatment. In the context of a DNR order, the patient has explicitly expressed their wishes not to receive CPR or resuscitation efforts, indicating their autonomy regarding end-of-life care.

Respecting a patient’s autonomy means recognizing their right to refuse certain medical interventions, and the DNR serves as a legally binding document that conveys this decision. Thus, by not performing CPR, the doctor honors the patient's preferences and respects their authority over their own body and healthcare decisions. This adherence ensures that the patient’s values and wishes are upheld, which is a crucial aspect of ethical medical practice.
