I’m an ECMO nurse in a CTICU, and an ECMO primer/educator in another role. I don’t have any formal specialty certification for it though — who offers it? I just have CCRN, and ACLS/PALS. Taking CSC soon.
I thought about perfusion for a bit too, but after shadowing a bypass case in the OR I decided I liked the craziness of the ICU a lot better. I’d recommend shadowing if you can!
