I would assume that they were "working" onhim during at least a decent portion of the time in question...
That would have meant that air was getting pumped in, and his blood was being circulated in some fashion...
But it is pretty darn amazing!
I'm glad that he made it; he seems like a real nice guy!
Our hospital was a teaching facility, not just for nursing, but, interns, residents, and fellows. The military has often been used by each other for learning situations. If you have been in the military you start out right away, they call them "battle buddies" now, he covers you, and you covers his.
The worst training situation I was involved in was when I was teaching one of my students how to insert a naso-gastric tube, I had just done one on a patient to evacuate his stomach contents, and I needed for the student to learn the procedure, his demonstration dummy was ME, he was trying to be so gentle, and the tube was right at my gag reflex, I couldn't talk, and the civilian LPN that was helping me out was laughing so hard, he couldn't tell the student to go faster, I can look back on it now and laugh, but at the time, I wanted to do the same thing to the student, but they frown on cruel and unusual punishment. Would I do it again, probably not, but after he got the tube down, and was able to do it well, I guess it was worth it. Funny thing is I ran into him in Korea at the 121 Evac Hospital. And you thought that was a fictitious place made up by the TV program MASH, actually my last assignment after I got back from Korea was with a MASH unit at FT. Riley, KS.
