The 45-Minute Problem: Why Medical Equipment Diagnosis Is Broken
Every hospital biomed director knows the math. A ventilator alarms — and a technician spends the next 45 minutes diagnosing before they can even begin the repair. The diagnosis consumed 75% of the total time and generated exactly zero billable hours. This isn't a training problem — it's a tooling problem.
