I have a DNR that I don’t carry around in my pocket. Rather it’s in my online medical records, and is the result of a consultation with my PCP. It's the responsibility of an attending physician, or nurse, to know my legal rights before administrating care.
If I woke up with you over me administering drugs that I didn’t request, I’d find the nearest Foley catheter and insert it so far up your rectum it would come out of your nose. Then, if you survived, I’d paper you with a lawsuit that would make the remaining hair on your head curl.
Don't ever touch me.
Now carry on!
No Fire/EMS Department on this planet is going to search electronic records that they don’t have access to for your DNR.
I suggest a well placed Tattoo on your chest could to the trick.
They are protected from Lawsuit Larrys that often threaten suits but can’t cough up the retainer fees, the depo fees, filing fees, etc.
