Someone mentioned doing a finger sweep earlier.. That's a no go if the PT is seizing. Good way to lose a finger and add a obstruction. Wallet or other soft object to kepp the mouth open, and something else to pull tongue up and allow you to visually see the airway. The hill up to the vehicle sounded to be steep, moving a full grown man, with clothing and dry suit on would be if'y for most folks. I have done sim rescues during training and it is much harder than you would think. Up hill would be not a very viable option for most folks I am afraid. add to that a suspected C spine injury.. I think I'd stick it out there and monitor the ABC's most convulsive activity does not continue, and they might improve after the first intial episode passes. The swollen tongue thing gets me. Are you sure your not my old EMT-II instructor back to haunt me with these wild senarios?
