Quick answer
HBOT means breathing 100% pure oxygen inside a chamber pressurised above two atmospheres, versus roughly 21% oxygen in ordinary air, driving far more dissolved oxygen into the bloodstream. Bong Bong Hospital lists it as one of Bong Bong Wellness Clinic's seven programmes, stating it accelerates cell renewal and supports immunity, and it is often paired with stem cell (Basic Cell) work so treated tissue has enough oxygen to repair itself.
