Published in the American Journal of Emergency Medicine (February 2026), this proof-of-concept crossover study evaluated continuous oxygen delivery during simulated difficult intubation using a porcine model. Oxygen was delivered through an endotracheal tube positioned near the vocal cords during apnea.

In the control arm without oxygen delivery down the ET tube, cutaneous saturation declined below 75% within approximately one minute. In the test arm with oxygen delivery down the ET tube, cutaneous saturation remained at or above 97% for the full 16-minute apnea period across each cycle.

Arterial blood gas results showed sustained oxygen levels along with an expected increase in carbon dioxide, a moderate decrease in pH, and totally normal lactic acid after 16 minutes of prolonged apnea. These findings reflect physiologic changes consistent with apnea while maintaining oxygenation.

Airway Oxygenation Brief (20-Min Clinical Discussions)
We are hosting short, clinician-led discussions focused on oxygenation during intubation – specifically where traditional approaches can fall short and how targeted airway oxygenation is being explored in practice.
These sessions are practical and discussion-based, bringing together perspectives from emergency, ICU, respiratory care, and EMS settings.
