HBOT for Long COVID and Post-Viral Fatigue — What Clinics Should Know

Who walks in the door

Long COVID patients typically present 6–18 months after infection with persistent fatigue, brain fog, exercise intolerance and sleep disruption. They have usually already tried conventional medicine with limited improvement. They are self-paying, motivated, and willing to commit to a 20–30 session protocol.

What the evidence supports

The honest answer is: promising, but not settled. Small controlled studies have shown improvements in fatigue and cognitive measures after HBOT protocols, but large definitive trials are still ongoing. Position HBOT as a supportive wellness option — not a cure — and you will avoid the two biggest mistakes clinics make: overpromising, and then disappointing patients who expected a fix.

How clinics run the program

• Initial consultation: history, current symptoms, medication review.
• Protocol: 60 sessions at 1.3–1.5 ATA, 5 sessions a week for 4–6 weeks.
• Re-assessment at 10, 20 and 30 sessions.
• Maintenance: 1–2 sessions a month once symptoms stabilize.

Why retention is high

Long COVID patients who feel some improvement tend to continue — because they have few other options that help. A clinic that runs a thoughtful program, listens, and adjusts the protocol will build a waiting list organically. The ones that churn patients are the ones that treated it as a one-size-fits-all ticket.

What to avoid

Do not market HBOT as "the cure for long COVID." Do not skip the contraindication screen (see article). Do not promise timelines. Do those three things and the program will grow on referrals rather than marketing spend.
