Can Hyperbaric Oxygen Therapy Help After a Concussion or TBI?

A concussion doesn’t always resolve on its own timeline.

Most people recover within a few weeks. But for a meaningful subset, symptoms like brain fog, headaches, light sensitivity, fatigue and slowed thinking linger for months — a pattern often called persistent post-concussion syndrome.

It’s one of the more frustrating outcomes in sports medicine and everyday injury recovery, because standard imaging often looks normal even when someone clearly doesn’t feel normal. That gap is part of why hyperbaric oxygen therapy (HBOT) has drawn so much research interest for traumatic brain injury (TBI) and concussion recovery.

At Core iV Therapy®, this is one of the questions we hear most often about our 1.3 ATA mild hyperbaric chamber: can it actually help with concussion recovery? Here’s what the research says — and where it’s still an open question.

Why Concussion Recovery Can Stall

After a traumatic brain injury, some tissue survives the initial injury but continues functioning poorly. Researchers describe this as tissue that is alive but metabolically compromised — affected by inflammation, disrupted blood flow, altered metabolism and impaired oxygen utilization.

That combination can leave a person with real, measurable symptoms even when a standard CT or MRI doesn’t show obvious structural damage. It’s one reason concussion recovery can feel so unpredictable — the injury isn’t always where the imaging looks.

Where Hyperbaric Oxygen Fits In

Hyperbaric oxygen therapy increases the amount of oxygen available to the body by combining increased atmospheric pressure with increased inspired oxygen. Researchers have investigated whether repeated HBOT sessions can influence neuroplasticity — the brain’s capacity to reorganize and adapt — and, by extension, persistent post-concussion symptoms.

A 2022 systematic review evaluated 11 studies involving persistent post-concussion syndrome. Several trials using repeated HBOT reported improvements in symptoms or cognition. But the review is candid about its limits: results varied by pressure and oxygen dose, and controversy remains regarding the use of sham (placebo) exposures in some trial designs.

In plain terms: there is enough evidence to make this area scientifically interesting, but not enough to call the debate settled. That distinction matters most for athletes and anyone with a history of concussion who is weighing HBOT as part of a recovery plan.

Why Dose and Protocol Matter

One theme runs through nearly all of the encouraging concussion and TBI research: it’s rarely built on a single session. Many of the studies that reported meaningful improvement involved dozens of repeated exposures over weeks or months.

That’s part of why our mild hyperbaric chamber operates at approximately 1.3 ATA — a pressure chosen for comfort and repeatability rather than intensity alone. A protocol someone can actually complete, session after session, is more valuable than an aggressive exposure they only use once or twice.

Our sessions also incorporate supplemental oxygen delivery by mask when appropriate, since pressure and oxygen concentration are two separate variables that work together to maximize oxygen exposure during a session.

This Is Not a Replacement for Emergency or Hospital Care

It’s worth repeating clearly: hospital-based HBOT, delivered at higher pressures (generally 2.0–3.0 ATA) in hard-sided chambers, is used for a specific set of established medical emergencies — decompression sickness, carbon monoxide poisoning and similar acute conditions. A concussion or TBI with any red-flag symptoms (worsening headache, repeated vomiting, loss of consciousness, confusion) needs medical evaluation first, not a wellness chamber.

Our 1.3 ATA protocol is designed for wellness, recovery and longevity support once someone is medically cleared — not as a substitute for emergency neurological care.

What This Looks Like at Core iV

For clients exploring HBOT for concussion or TBI-related symptoms, we generally emphasize:

• Meaningful session duration, typically around 60 minutes at therapeutic pressure
• Supplemental oxygen delivery by mask
• Repeated, individualized sessions rather than a single one-off visit
• Honest framing — this is supportive and investigational, not an established cure

Some clients also pair sessions with other recovery-focused therapies as part of a broader protocol, with hyperbaric oxygen typically used as the final step.
