Clinical training has to feel real, repeat on demand, and harm no one.
Hands-on emergency-room practice is the part of training that sticks, and it is the part that is hardest to give. You cannot rehearse a code blue on a real patient, and a recording of one is something to watch, not something to do.
So nurses learn the steps in the abstract and meet the pressure later, for the first time, on a person who needs them. The team wanted a setting where a trainee can run the same scenario again next week, fail without consequence, and try the harder version once the basics land.
It also had to be a group exercise. Real emergency care is a team moving around one bed, handing off tasks and talking through them, so the training had to put several people in the same room at once.
