Breathing thin air to protect your throat: a new hope for TBI swallowing?

This small study tested a technique called acute intermittent hypoxia (AIH) — breathing low-oxygen air for short periods — to see if it could improve swallowing safety in people with chronic mild-to-moderate traumatic brain injury (TBI). Five adults completed the study, which combined AIH with swallowing exercises. The goal was to see if this approach could reduce the risk of food or liquid going into the lungs (aspiration). Results are not yet reported.
