To Viewers Who Are Medical Professionals

I'm not in medicine but my husband is a pulm/ICU attending, and he's been really impressed with the show thus far. It's really fun to have his commentary (mostly "nice!" / "oh no wrong choice" / "hell yeah" / "goddamn Lucas" / "why isn't anyone wearing a mask" ). He actually even learned a technique he's never seen before from the latest episode (following air bubbles to intubate when you can't use suction).

I was wondering if any other medical viewers have spotted things they've never seen in practice or brand new info? I do spend a lot of time pausing and asking "ok what would you do here?"
