A cuff that waits, the way a real one does

Fourteen seconds of nothing, on purpose

Press Start NBP and the screen doesn't jump to a number. It shows a cuff-inflating indicator for about fourteen seconds first, the same wait a trainee learns to work around on a real ward, before the reading appears. Skipping that wait would teach the wrong lesson: that a pressure is always one tap away.

Scheduled, not just on demand

Tap the NBP field on the monitor to set an automatic interval, from every minute to every thirty, just like the interval mode on a real bedside monitor. A single reading can still be taken at any point in the scenario. Both paths go through the same fourteen-second cycle.

A cuff can't lie about a pulse that isn't there

In a pulseless rhythm, the cuff doesn't return a plausible-sounding number. There's no pulse for it to detect, so the Patient Simulator returns a failed reading instead, the same result a real oscillometric cuff gives when it can't find one. A monitor that quietly makes up a blood pressure during a cardiac arrest is teaching the trainee to trust a number that shouldn't exist.

Different from an arterial line, deliberately

A real patient can carry both an intermittent cuff and a continuous arterial line at the same time, and they don't behave the same way. The Patient Simulator keeps them as two genuinely different measurement types, not one number shown twice, so trainees learn what each one can and can't tell them.

Why the cuff and the arterial line rarely show exactly the same number is explained in NBP vs ABP.
