There is something that interests me a lot: I would like to know what experience you have in treating COVID patients with Hyperbaric Oxygen Therapy (HBO). The European Society (Undersea & Hyperbaric Medical Society) and the European Committee (European Committee for Hyperbaric Medicine) have issued statements advising against it, however, to the ASEMHS (Spanish Association of Hyperbaric and Underwater Medicine), multiple reports of good results with HBO are coming, at different levels of severity of the disease. The Italian Society has proposed to do a experimental study, and we know that in China they have also used it. What are your experiences?
