What this trial studies

This is a pragmatic, double-blinded, randomized interventional trial testing hyperbaric oxygen therapy (HBOT) for PTSD. Participants are randomized to receive HBOT or a blinded sham in a hyperbaric chamber while breathing oxygen at a partial pressure above 1 atmosphere. The protocol requires a course of repeated treatments delivered five days per week, with clinical outcomes measured by changes in PTSD symptoms and functional status. The trial is conducted at the INMI facility in Ramat Gan, Israel, and includes efforts to enroll both men and women.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18–80 with a DSM-5 diagnosis of PTSD severe enough to warrant discharge from military service and who can commit to the full course of treatments.

Not a fit: People with current or past psychotic or manic disorders, active suicidal ideation, pregnancy, untreated pulmonary or ear pressure-equalization problems, or those unable to attend the required 120 sessions are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, HBOT could reduce PTSD symptoms and improve daily functioning for affected adults, offering an additional treatment option.

How similar studies have performed: Previous controlled trials in mTBI (with many participants also having PTSD) have produced mixed results, and a small unblinded PTSD-only study showed improvement but had major methodological limitations, so evidence is inconclusive.
