PCU/stepdown whaaaat the heck

Why does no one ever really talk about PCU/stepdown Units? Like it requires the cognitive demand of ICU, with less support and a heavier task load. Why did no one warn me lol. First chance I get I am heading to the ICU! Any good pointers to help reconcile that I don't get to monitor the patients for early detection of decline like they need because I am being overloaded with tasks and interactions and logistical failings of hospitals and technology
