Can hyperbaric oxygen therapy help with Long COVID symptoms?

Research published in Nature Scientific Reports shows hyperbaric oxygen therapy can help with Long COVID symptoms.

Why does hyperbaric oxygen therapy help Long COVID brain fog specifically?

Long COVID reduces blood flow and causes damage in the brain areas that control attention, memory, and mental speed. Inside the chamber, the added pressure drives far more oxygen into your blood — enough to reach tissue that tiny clots had cut off. That oxygen helps grow new blood vessels, rebuild brain connections, and calm inflammation, with the changes confirmed on follow-up MRI scans.

How many HBOT sessions are needed to treat Long COVID?

Research published in Nature Scientific Reports shows treatment protocols typically involve multiple sessions over several weeks.

Is HBOT safe for people living with Long COVID?

For most people, yes. A 2025 clinical trial (BMJ Open, 80 patients) found a strong safety record in Long COVID patients. The most common side effect is mild ear or sinus pressure during the session — like the feeling when a plane comes in to land — and your RevitalIV provider will show you how to manage it. We screen for the few conditions and medications that aren't a good fit before you start, and every session is supervised by a physician.

How soon will I feel results from HBOT for Long COVID?

Many patients notice a difference within the first 2–4 weeks. One 2022 case study reported less fatigue after 15 sessions, with memory, multitasking, and breathing back to pre-COVID levels by session 20 — confirmed by formal testing. Sleep and energy tend to improve first, while the mental gains build over the full course. Results vary from person to person, and HBOT isn't a guaranteed cure.

Can HBOT treat Long COVID fatigue and post-exertional malaise?

Yes. Long COVID fatigue often comes from damage to the tiny power plants inside your cells — which is why rest alone doesn't fix it. HBOT floods your cells with oxygen well beyond normal breathing, helping them make energy again. Across multiple clinical trials, fatigue improved significantly.

Does insurance cover HBOT for Long COVID?

Usually not. Because HBOT isn't FDA-approved specifically for Long COVID, most insurers treat it as experimental and won't cover it. RevitalIV offers it on a cash-pay basis, and we provide detailed receipts (called superbills) you can submit to your insurer — some patients have received partial out-of-network reimbursement. Check with your insurer before starting, and ask our team about financing options during your free consultation.
