Yes, exactly. In an arrest situation it's really difficult, you might have 5, 6, 7 people in that room with you, and with a tiny premature baby you're going to struggle to see. Having a set list of what we look for helps lighten the cognitive load.
Additionally, you've got to remember that most doctors do not know what a rash looks like with air embolus. I can't even find an example of the rash easily on google (for obvious reasons) - I've had to go through a couple of different articles, find the latin name, then look that up because that's apparently what it looks a bit like in divers when they get a cerebral air embolus (which is different too!). The rash that an air embolus apparently 'looks like' occurs in 50% of newborns as well, the weird thing about it here is that it specifically disappeared when the baby got better...
For reference, this is the rash the articles say the cerebral air embolus in divers looks like, I've seen something similar in a lot of babies that is permanent, especially newborn ones. Remember that Baby M is only 2 days old at this point.
