Actually had something similar happen to me a few weeks ago. Medic crew coming from an outlying hospital was asking for another medic because their patient just coded. My partner hopped in the back of their truck, and I followed in ours. Unloaded pt at ER, rode the rails into room.
Weird thing #1: Pt's chest would not rise after compressions.
Weird thing #2: Pt was pushing our arms away during compressions, but when we would stop, so would she, as she had no pulse, no respiratory effort. It was obvious she was trying to keep us away.
Weird thing #3: Pt WALKED out of the hospital one week later.
It's official. Patients are weird.
