About this trial
The purpose of this study is to evaluate how hyperbaric oxygen therapy (HBOT) may affect cognitive functioning, post-traumatic stress disorder (PTSD), depression, anxiety, and overall quality of life in veterans.
1. Does Hyperbaric Oxygen Therapy improve cognitive functioning, psychological well-being, and quality of life among veterans, as measured by pre-and post-treatment scores? 2. To what extent does Hyperbaric Oxygen Therapy improve cognitive functioning, psychological well-being, and qualify of life among veterans, after controlling for demographic characteristics.

Hyperbaric Oxygen Therapy
DrugEach HBOT session is scheduled for approximately 95 minutes. The session will begin with a descent of up to 15 minutes (longer if needed for comfort/safety) to a pressure of 2.0 ATA, followed by 30 minutes of breathing 100% oxygen. At the midpoint, there will be a 5-minute air break from oxygen, after which subjects resume breathing 100% oxygen for another 30 minutes. Finally, the session will conclude with an ascent of up to 15 minutes (longer if needed for comfort/safety) back to 1.0 ATA. All sessions are delivered under direct medical supervision with standardized safety protocols. Once approved after medical and behavioral screening, participants complete a battery of cognitive, mental health, and quality of life assessments at baseline (pre-) and after completing the therapy (post-). This arm is distinct from any sham or control interventions because all participants receive the active HBOT treatment.
