Augmented Reality Smart Glasses Versus Video Laryngoscopy During Ambulance Transport
Sponsor: ONUR KARAKAYALI
Summary
This randomized crossover simulation study evaluated the performance of augmented reality (AR) smart glasses compared with conventional video laryngoscopy (VL) for endotracheal intubation under simulated prehospital ambulance conditions. Prehospital emergency care professionals performed endotracheal intubation using both AR and VL in a stationary ambulance and in a moving ambulance. The moving ambulance scenario was conducted on a standardized 1-km training track at a constant speed of 20 km/h and included four speed bumps and four 90-degree turns. Each participant completed all four study conditions in a randomized sequence. The study primarily evaluated intubation performance, including total intubation time, and additionally assessed procedural performance, success, glottic visualization, and participant-reported workload and usability.

Conditions
Interventions
Augmented Reality-Assisted Laryngoscopy
Endotracheal intubation was performed using an augmented reality (AR) smart-glasses system that displayed the laryngoscopic video image within the participant's field of view. The system enabled participants to visualize the airway while maintaining a forward-facing head position. The intervention was evaluated under both stationary and moving ambulance conditions using an adult airway management trainer. Remote guidance and annotation functions were not used during the study.
Video Laryngoscopy
Endotracheal intubation was performed using a video laryngoscope (VL), with the airway image visualized on the device's external display. The intervention was evaluated under both stationary and moving ambulance conditions using an adult airway management trainer. Participants performed the intubation according to the randomized crossover sequence assigned to them.
