In a hospital and Cardiac Cath, 30 years (on a break, by the way). In my opinion, you never screw up when you hit the Code Button. Yeah, it was a dud and I've gone to those, but what if it wasn't? I'd rather hit it and be wrong than to lose heart muscle dithering on whether to call a Code or not. No my friend, it was no trouble whatsoever calling it.
