Electrical impedance tomography patient monitor LuMon™

bedsidebreathingintensive care

Overview
The Sentec LuMon™ System is an electrical impedance tomography (EIT) monitor that provides continuous, real-time, radiation-free functional imaging of regional lung ventilation at the bedside. It translates impedance measurements into intuitive images and quantitative metrics to support personalized ventilation and respiratory-care decisions across neonates, pediatric and adult patients.

Key benefits

• Continuous, real-time, noninvasive monitoring at the patient bedside
• Radiation-free assessment of regional lung ventilation and recruitment
• Supports individualized ventilation strategies and PEEP titration
• Helps identify under-ventilated (Silent Spaces) and overdistended regions
• Enables proactive interventions to reduce ventilation-associated complications

Clinical applications

• Neonatal intensive care (NICU): monitoring and tailoring ventilation in very small chest circumferences
• Pediatric care: visualization of ventilation distribution and response to interventions
• Adult critical care and ICU: bedside guidance for ventilation, PEEP adjustment and prevention of ventilator-induced lung injury
• Perioperative and anesthesia settings, home ventilation follow-up and sleep medicine contexts

Technology & Features
The Sentec LuMon™ System applies safe alternating electrical currents via a soft thoracic belt to measure resulting voltages and compute regional impedance changes. Proprietary algorithms convert impedance data into real-time images and numerical measures of regional air distribution and recruitment for clinical decision support.

• Modes for visualization and interpretation (e.g., VentView, Stretch, Silent Spaces, global/regional dynamics)
• Detection and tracking of Silent Spaces (poorly ventilated regions)
• Real-time assessment of effects of PEEP and ventilator setting changes on recruitment and compliance
• Customizable display configurations and integration options with bedside devices and ventilators
• Skin-safe, non-adhesive fabric belts available from neonatal to adult sizes; integrated orientation sensor for automatic patient position tracking
• Some features may vary by system version or country

Use in the NICU
The LuMon™ System is configured to address neonatal physiology (small airways, compliant chest walls, low absolute lung volumes). It supports assessment of lung recruitment regardless of ventilation mode, visualization of distribution patterns, and identification of potential overdistension or collapse to guide targeted interventions.
