Assessment

Well, after the months of waiting it's here. Sunday I have to do my IHCD assessment to be BRC ambulance crew. Part of me thinks that I have done it all in training and should be OK, however a much bigger part is thinking "Run away and hide" I am honestly bricking it, I can feel my stomach cramping up even just typing this. I just hope that on the day I will be calm and perform as well as I can, my real fear is doing the hard things right and messing up on the basics

What's this EAR

A plea for help.
I have not been writing much as my BRC ambulance assessment is coming up soon, however one thing has me puzzled. The IHCD manual, when talking about drowning says to get the pt on O2 or EAR whilst still in the water if necessary, however in it's normal really helpful way it does not explain what EAR is. Any ideas?
