Protocol
Hyperbaric oxygen therapy is one of the most researched interventions for Long COVID, with clinical trials showing significant improvements in fatigue, brain fog, breathlessness, and quality of life.
Long COVID — also called post-acute sequelae of SARS-CoV-2 (PASC) — affects an estimated 10–30% of COVID-19 survivors and is characterized by persistent symptoms lasting months or years after the acute infection. The underlying mechanisms include microclots impairing tissue oxygenation, neuroinflammation, mitochondrial dysfunction, and autonomic nervous system dysregulation. HBOT addresses all four pathways simultaneously: pressurized oxygen breaks down microclots, reduces neuroinflammation, restores mitochondrial function, and supports the nervous system's healing. A landmark 2022 randomized controlled trial published in Nature Medicine demonstrated that 40 sessions of HBOT produced significant improvements in cognitive function, fatigue, sleep, pain, and psychiatric symptoms in long COVID patients vs. sham treatment.
Quick facts
What happens during a session?
The 2022 Nature Medicine protocol uses 40 sessions at 2.0 ATA for 90 minutes each. At this pressure, oxygen dissolves into plasma and tissue fluid at 10–15× normal concentration — enough to reach microclot-blocked capillaries and hypoxic tissue. The hyperoxygenation environment promotes clearance of fibrin microclots, reduces inflammatory cytokines that drive brain fog and fatigue, restores mitochondrial ATP production, and supports the neuroplasticity changes that address cognitive symptoms.

- Anxiety and mood changes post-COVID
- Chronic pain and neuropathy
Common questions
Is there real evidence HBOT helps Long COVID?
Yes — a 2022 randomized controlled trial in Nature Medicine found 40 sessions of HBOT produced statistically significant improvements in cognitive function, fatigue, sleep, pain, and psychiatric symptoms vs. sham treatment. It is one of the strongest trials in the Long COVID treatment literature.
How many HBOT sessions do Long COVID patients need?
The established protocol is 40 sessions at 2.0 ATA for 90 minutes each, 5 days per week. Most patients notice improvement within the first 20 sessions.
Does insurance cover HBOT for Long COVID?
Not currently. Long COVID HBOT is off-label and not covered by Medicare or most private insurers. Costs are out-of-pocket. Some patients use HSA/FSA funds or clinical trial enrollment where HBOT is provided at no cost.
Where can I find a clinic doing Long COVID HBOT?
Search FindHyperbaric and filter by 'Long COVID' to find clinics with experience treating post-COVID patients. Look for providers who follow the 40-session, 2.0 ATA protocol from the Nature Medicine trial.
