RPM Alarm Threshold 2D: Sensitivity vs Alarm Fatigue

Remote patient monitoring only works if its alarms are trusted, and trust depends entirely on where the threshold is set. This simulator renders a 42-bed telemetry ward where each bed streams a noisy heart-rate signal — most patients healthy, a tunable fraction genuinely critical — and lets you drag the single number a real RPM system alarms on. A live chart beneath the ward draws the two populations' overlapping bell curves to scale, shaded by outcome (true/false positive/negative), so you can see exactly why "just lower the threshold" is never a free fix for alarm fatigue in telehealth monitoring. A one-click Youden's-J button jumps to the statistically optimal cutoff for the current separation.
