Can pressurized oxygen calm the storm of PTSD?
NCT ID NCT07473362
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether breathing pure oxygen in a pressurized chamber (hyperbaric oxygen therapy) can reduce symptoms of post-traumatic stress disorder (PTSD). About 72 adults with PTSD will receive 60 treatments over 12 weeks, and researchers will track their symptoms for up to two years afterward. The goal is to see if this therapy offers lasting relief from PTSD.
