A DNR is usually discussed when the patients health problems mount to the point that where continuing treatment will just basically prolong the suffering.
In Texas at least, any person on scene can revoke the DNR, even against the patient’s wishes, by just saying “work them.”
In 30 yrs, I have never encountered a DNR that didn’t appear to be based on an informed decision.
Interesting.
Our medical systems up here and doctors are all pushing DNRs and living wills.
