Protecting Critical Medical Equipment via CEGMA
A major hospital deployed CEGMA's intelligent asset management platform to protect life-critical medical equipment—achieving zero equipment failures attributable to electrical supply issues for 18 consecutive months.
The Challenge
“Hospitals operate with an unusual electrical maintenance challenge: life-critical medical equipment (MRI systems, ICU monitoring equipment, operating theater electrical systems, emergency backup power) demands exceptionally high electrical reliability, yet maintenance shutdowns for electrical work must be planned with extreme care to avoid interrupting patient care. The hospital's facility management team was managing electrical maintenance reactively—responding to equipment failures and power quality complaints rather than proactively managing electrical system health. Two near-miss incidents involving power quality disturbances affecting ICU monitoring equipment prompted a strategic review.”
The Solution
CEGMA (an Innvendt product line for critical facility applications) was deployed across the hospital's electrical distribution system, with continuous monitoring of power quality, earth resistance, leakage current, and UPS battery health at all clinical areas. CEGMA's healthcare-specific alert classification and escalation workflows integrate with the hospital's facilities maintenance management system and clinical engineering team, ensuring that electrical alerts are triaged against patient care priorities before maintenance is scheduled.
Implementation
Clinical Area Prioritization and Risk Mapping
CEGMA deployment began with a clinical risk mapping exercise: the biomedical engineering and facilities teams jointly classified every hospital area by electrical dependency criticality (Level 1: life-critical; Level 2: critical care; Level 3: general clinical; Level 4: administrative). Monitoring density and alert thresholds were calibrated to the criticality level of each area, with Level 1 areas receiving the highest monitoring density and the tightest alert thresholds.
UPS and Emergency Power Monitoring
CEGMA's UPS monitoring module was integrated with the hospital's 47 UPS systems covering critical clinical areas. Continuous monitoring of UPS battery capacity, charge/discharge cycles, and internal temperature enabled proactive battery replacement before end-of-life, replacing the hospital's previous practice of annual battery testing which had missed mid-cycle battery failures. UPS runtime estimates were displayed in real time to the facilities team, providing accurate visibility into backup power duration during normal utility supply events.
Maintenance Coordination with Clinical Scheduling
CEGMA's maintenance scheduling module was integrated with the hospital's clinical scheduling system to coordinate electrical maintenance windows with low-risk clinical periods. Proposed maintenance windows were automatically checked against the clinical schedule for conflicts (scheduled procedures requiring uninterrupted power in the affected area), with alternative windows suggested when conflicts existed. This integration eliminated the previously common scenario where electrical maintenance was scheduled without awareness of concurrent clinical activities.
