HBOT 101 for Patients

Hyperbaric oxygen therapy (HBOT) means breathing 100% oxygen inside a pressurized chamber. The pressure lets your blood dissolve far more oxygen than normal — reaching injured tissue that ordinary breathing can't. Over a course of relaxed 60–90 minute sessions, that extra oxygen helps your body grow new blood vessels, fight infection, and heal.

Why pressure matters

At sea level your red blood cells are already nearly full of oxygen. Under pressure, oxygen dissolves directly into the blood plasma — the liquid part — which can travel where red cells struggle to go. That's the whole mechanism.

HBOT has 14 FDA-recognized indications with strong evidence — things like non-healing diabetic wounds, radiation injury, and serious infections. It also has off-label uses where the evidence is promising but not settled. The honest rule: for recognized indications it's established medicine; for off-label uses, ask exactly what the studies show. Our eligibility analyzer gives you a candid read in two minutes.

You recline in the chamber and, as pressure rises over a few minutes, your ears feel like a plane descending — you'll learn to clear them easily. Then nothing: you breathe normally for 60–90 minutes while watching a film or napping. Most people find it genuinely relaxing. A technician monitors you the whole time.

For recognized indications, Medicare and most insurers cover HBOT when clinical criteria are met — you typically pay only your normal copay. Off-label uses are self-pay. Reputable clinics verify your coverage for free before you commit and quote a clear total for self-pay courses. Try our cost estimator for a ballpark.
