Most oxygenation strategies used during intubation begin at the nose – 14 cm from the vocal cords. This study explored what happens when oxygen delivery is repositioned much closer, near the actual glottic inlet.

Recently presented at the Canadian Association of Emergency Physicians in June of 2026, investigators evaluated the Turbo® O₂ Cap in a difficult-airway porcine model. The device attaches to a standard endotracheal tube and directs oxygen toward the glottic inlet during apnea. Twelve apneic intubation cycles were performed, comparing standard conditions with and without oxygen delivered through the device.

This highlights oxygen saturation trends and arterial blood gas measurements collected during 15-minute apnea periods, providing additional insight into oxygen delivery at the level of the vocal cords.
