Using low oxygen exposure to improve airway protection in brain injury patients

Acute Intermittent Hypoxia to Improve Airway Protection in Chronic Traumatic Brain Injury

Not applicable Interventional University of Florida · NCT06520358

This study is testing if breathing low oxygen for short periods, along with special training, can help people with mild to moderate brain injuries improve their airway protection and recovery.

What this trial studies

This study investigates the effects of acute intermittent hypoxia (AIH) combined with task-specific airway protection training on individuals with chronic mild to moderate traumatic brain injury (TBI). Participants will undergo brief episodes of low oxygen breathing to stimulate neuroplasticity, which may enhance their rehabilitation outcomes. The study employs a double-blind cross-over design to compare the effectiveness of AIH plus training against training alone. The goal is to determine if this combined approach leads to better airway protection and overall recovery.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21-80 with a mild to moderate traumatic brain injury and a Glasgow Coma Scale score between 9-15.

Not a fit: Patients with severe neurological disorders, significant psychiatric conditions, or pre-existing pulmonary diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve airway protection and rehabilitation outcomes for patients with chronic traumatic brain injury.

How similar studies have performed: Previous studies have shown promising results with acute intermittent hypoxia in enhancing motor function after neural injury, indicating potential for success in this novel approach.
