(Tip: for the above indications, some diseases hyperbaric oxygen can be used as the first choice of therapy, its main role, clinical efficacy is certain; some diseases hyperbaric oxygen can be used as one of the adjuvant treatment methods, can improve the efficacy; some diseases hyperbaric oxygen has certain efficacy, but further research is needed. (Therefore, for each specific patient, the effectiveness of hyperbaric oxygen therapy needs to be consulted with a specialist physician.)
