Also add Sgt. Major John Twomey to your prayer list. VN Vet, was Sgt.Major at Camp San Luis Obispo and Camp Roberts for CA Guard. Was on extended active duty during Gulf War run up active duty when his Agent Orange exposure caught up with him.
As far as a DNR/DNI order, that may be his wishes. If a patient in a acute care facility under close to intensive care conditions and they reach a point where they need resuscitation or intubation they are in really bad shape and likely aren't going to recover. All resuscitation or intubation will do is keep them alive in frankly poor, hell, shitty conditions for a few days. My Dad had a DNR/DNI request and we didn't like it but it was his desire. He had Pulmonary Fibrosis and it would have been only a temporary measure at best.
