It may be time to start taking the organ donor star off your driver licenses, unless you want certain medical professionals to prefer to harvest your organs, rather than render life saving treatment, even with visible signs of cognition.
I've been hearing from people who deal with some hospitals that if you have 'low survival odds', they go straight to organ harvesting instead of life saving treatment, and count on the person being dead/harvested before anyone can say otherwise, and that an organ donor sticker is as good as a 'DO NOT RESUSCITATE' bracelet or directive if the medical group involved feels the organs are worth more than saving the patient.
