Another huge help:

Snoofy, have you seen The Pitt? It's set in an ER in Pittsburgh, and won the Emmy in its first year for best drama. Noah Wylie is the lead, as well as executive producer. It's terrific.

ER professionals have praised the show as the most realistic they've ever seen.

The premise is cool as well: each episode is one hour in the same day; the entire season takes place over 15 episodes/hours. They are clearly condensing a few things (the hospital administrator comes by every 15 minutes, it seems), but it's got some terrific writing and great acting. Noah Wiley won the Emmy, and the charge nurse won for best supporting actress.

They've obviously got lots of great technical advisors, but Wylie also hired a choreographer, to make sure everyone could get into their place smoothly, and make it look like they've been doing it for ten years.

It's on HBO Max, if you're looking for it. Highly recommended!
