Summary

This study looks at whether turning down the volume of anesthesia alarms can help surgical trainees think more clearly during operations. About 26 surgeons will perform simulated surgeries with either standard or quieter alarms. Researchers will measure mental workload using heart rate and pupil changes, plus simple questionnaires. The goal is to find a sound level that keeps patients safe without overwhelming the surgeon.
