Blue Mirror AI is an observational AI tool that automatically assesses and corrects errors in your team's PPE application. Operating through a wall-mounted tablet, Blue Mirror AI replaces your traditional PPE buddy, and checks for errors in donning and doffing your PPE kit. It saves time, money, and resource, and improves infection control and minimises the spread of infections by reducing PPE errors. The system can also be used in training mode, helping to train medical students and refresh the knowledge of clinicians.
