During a hyperbaric oxygen treatment, the patient lies in a hyperbaric chamber for between 60-90 minutes, during which the atmospheric pressure is slowly increased. During the treatments, you breathe 100% pure oxygen. Under normal conditions, hemoglobin carries oxygen to all the body’s cells. Hyperbaric oxygen therapy saturates the serum in the blood vessels that carry hemoglobin, enabling them to deliver 10-15 times more oxygen. This saturates the body’s tissues – reversing hypoxia (low oxygen levels) – and creates cell healing.
