TRAINING USE ONLY — NOT FOR LIVE PATIENTS The Augmented Infant Resuscitator (AIR) Companion app connects—via Bluetooth—to the AIR sensor, a mannequin-based training tool that helps birth attendants master newborn ventilation. It monitors ventilation quality and provides real-time, objective feedback and actionable cues to users. Saves session scores so trainees and instructors can review progress over time. Use it exclusively with mannequins during simulation or skills-lab sessions.
