I would not wear a DNR bracelet, only an allergy bracelet…my father was dying of heart issues. He was being kept alive with chemicals. I’d always say to his doctors: give him the drugs..,I am not his god, his god will take him when he/she/it is nice and ready, not me!’ Gratefully, M

I agree and they have loads of other complex issues to deal with. They train, train, and train some more is all that I can hope for and try my best to make my wishes known.

This rather long article published in the Turkish Journal of Emergency Medicine has been around for some time and clearly documents your point. With respect to DNRs:
"Making the initiation of prehospital CPR more ethically complex is a Do-Not-Resuscitate (DNR) order. DNR has no basis towards making decisions about the current treatment but only avoids resuscitation.[23] DNR conflicts are one of the most frequent dilemmas reported by emergency medical technicians.[24]

"When confronting these challenges, the majority of the paramedics relied heavily on the advice of medical experts, but some had to make more autonomous decisions.[25] In general, if there is any doubt about the appropriateness of withholding resuscitative attempts, CPR should be initiated.[26]"

That quote is almost near the end of the article but before getting there covers some other complex issues.

It may be difficult for them but honoring the last request of their fellow man should also be considered an honor. Just my pov.
