I hate that saying, I hate it, hate it hate it, just like the saying Diesel bolus. and many others.
I literally save my emt's life, yep, yep I did. Ask me how we did it, it's a fun story. Scary as hell when it happened. But I did. He was sick, real sick with the shit's/pukes. We started a bananna bag on him, the minute the fluid went in him, he had an anaphylactic reaction to the dye in the bag. He nearly coded, but I gave him 0.3 epi and some benadryl and thus saved his life.
That's it, thats how I saved his life. Not fancy, I didn't get a medal.
But that's all I did.
