A Do Not Resuscitate (DNR) order is a medical directive written by a physician, based on discussions with patients or their surrogates, to forgo cardiopulmonary resuscitation in certain circumstances such as when resuscitation would be futile or burdensome. The document outlines the principles of patient autonomy, the importance of advance directives, and the ethically complex scenarios that can arise in decision-making about DNR orders. It emphasizes the need for clear communication and documentation, as well as the potential legal implications of these decisions.
