Hyperbaric Oxygen Therapy of Arizona's website describes its Phoenix clinic as the most trusted, cutting edge hyperbaric oxygen treatment facility in the area. HBOT works by taking oxygen and placing it under greater than normal pressure, pushing oxygen into the blood plasma, tissues, and body fluids to super-oxygenate the entire system. The therapy is described as helping to detoxify the system, reduce inflammation, increase cell production, and improve cardiovascular circulation. Stated benefits include increased neuronal energy metabolism in the brain, sustained cognitive improvement, enhanced ability to fight bacterial and viral infections, deactivation of toxins and poisons, and stimulation of new capillary growth into injured areas. The veteran-owned clinic received a grant from the Southwest Veterans Foundation to help veterans access therapy not covered by insurance or the VA. A patient testimonial specifically credits HBOT for helping with long covid.
