According to this WHO (World Health Organization) report: “Oxygen therapy is the main treatment intervention for patients with severe COVID-19. All countries must work together to optimize the availability of pulse oximeters and medical oxygen systems. Mortality in people with critical illness has been reported as above 50%, therefore the implementation of proven intensive care interventions such as respiratory protection should be optimized. ”
Since oxygen can help with infection, it means IHT (Intermittent Hypoxic Training) performed before infection can strengthen immunity, strengthen the cardiopulmonary system and significantly reduce the risk of serious complications during infection.
