I just came from what would be considered a CAH. I had a gsw to the neck, a 19mo pediatric death in the ER that I had to lifeflight with, hangings, someone got drunk and fell out of 4 story window, workers falling off of three story scaffolding , GI bleed with only 2 units of blood in the hospital, MVAs, and lots of people coming to the OR with unknown etiologies that end up being pain to deal with it in the OR. That was all in less than years time. It isn’t about the volume but the amount resources you have to deal with it. In a CAH you’re it and you do it all often as the only anesthesia provider.
