This disclosure describes a solution to enable more useful and responsive methods for a person's wishes for resuscitation actions to be canceled or discontinued in the event of a medical event. In this solution, a person can record their do not resuscitate (DNR) wishes with more specificity. For instance, they can specify conditions for treatment or non-treatment in the event of a medical emergency that would otherwise call for live-saving procedures or the use of an automated external defibrillator (AED) device. Conditional DNR data can be recorded in an electronic device (e.g., emergency pendant or smart watch, or in an electronic device) implanted within or on the person's body. This data can also be stored in a database accessible via a network.
