Given the well-known benefits of increased oxygen levels and decreased inflammation generated by hyperbaric oxygen therapy, doctors have been using this knowledge in the battle against the disease. Several news sources have recently reported the successful use of hyperbaric oxygen therapy (HBOT) by physicians in Louisiana and New York hospitals for the treatment of patients infected with COVID-19. The patients noted were most likely to be placed on mechanical ventilators, given their course of non-response to nasal O2 supplementation and treatment with medications. Patients treated with HBOT responded favorably and their conditions improved, downgrading their need for ventilators. Researchers and doctors in the U.S., Korea and China hope to continue their studies and publish conclusions over the following months. Encouraging news indeed from the front lines of the war against the coronavirus.
