Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 16 to 65 who present with severe TBI and meet specific clinical criteria.

Probably not a fit

Patients with pre-existing neurological diseases or those who cannot receive treatment within the specified time frame may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase II trial aims to identify the optimal parameters for hyperbaric oxygen (HBO2) treatment in patients with severe traumatic brain injury (TBI). The study will evaluate various combinations of pressure levels and the potential enhancement of treatment effectiveness through the use of non-breathing hyperbaric (NBH) techniques. By determining the most effective HBO2 treatment parameters, the trial seeks to provide critical data for a future definitive efficacy trial. The focus is on minimizing oxygen toxicity while maximizing therapeutic benefits for patients.

Why it matters

Potential benefit: If successful, this treatment could significantly improve recovery outcomes for patients with severe traumatic brain injury.

How similar studies have gone: Previous studies have indicated potential benefits of hyperbaric oxygen therapy in TBI, but this specific approach is novel and aims to refine treatment parameters.
