Someone once put it to me, "Running a code isn't as much of a big deal. I mean, the patient's already freaking dead at that point, how much more can you really **** it up? It's when they're crashing before they've died that is a big deal."
Ok, that's a little dramatic, but remember, if they have no pulse, as long as you start and keep the chest compressions going, you have plenty of time to play a head game with yourself: tell yourself you have all the time you need, all the time in the world to just take a step back, relax, take a deep breath, gather your thoughts, get out your ACLS, and follow the recipe. Doing this seems like it takes a lot of time, but it's only seconds, and staying calm with your wits about you makes the whole thing much easier and faster in the long run. The hard part is having a cool non-panicked head, and realizing that as long as the chest compressions are going, you do have the mere seconds it takes to run the card, AKA run the code.
Repeat after me: the chest compressions are going, I have time to think.
Or just talk all your admits into being DNR/DNI and you won't have to deal with it. You can just let them die, and dead patients are a lot easier. (OMG I AM J/K OK).
If this isn't a pulseless arrest, then they're still alive and live patients are scary and I don't know what to tell you. Living patients on the edge of death are above my paygrade.
