Currently, ozone is mainly used in clinical practice to treat vaginitis. During treatment, if ozone is inhaled into the body, there needs to be enough hemoglobin to carry oxygen to neutralize the ozone. A small amount of inhaled ozone will not cause any damage to the body, but if a large amount of ozone is inhaled, it will need to be ameliorated by low-flow continuous oxygenation. In an environment with good air circulation, the concentration of ozone is diluted away and a state of asphyxiating toxic hypoxia is not produced. Therefore, the room in which ozone therapy is performed should be ventilated, i.e., there should be an exhaust fan.
