Alarm fatigue in critical care units contributes directly to burnout and delayed response to actual arrests. This study quantifies the impact of multi-signal morphological filtering on alarm validity across 10,000 patient-hours.
When an ECG channel reports asystole but the arterial catheter shows robust pulsatile pressure, the event is immediately triaged as an electrode detachment rather than cardiac arrest.
Deploying the SQI pipeline decreased audible bedside alerts by 82.4% while maintaining 100% sensitivity for true ventricular tachycardia, fibrillation, and hemodynamic collapse.
