The use of hyperbaric oxygen in infants can have the following effects: first, to restore brain damage. If an infant suffers from encephalitis or other brain diseases, the brain cells are damaged and hyperbaric oxygen can be used to treat the infant during the acute phase of the damage. Second, to improve the symptoms of carbon monoxide poisoning in infants. If the infant has carbon monoxide poisoning, it will cause coma and red lips and other symptoms. The application of hyperbaric oxygen can discharge the carbon monoxide in the blood as soon as possible and improve the symptoms of carbon monoxide poisoning in infants. It is important to apply hyperbaric oxygen to infants as soon as possible, but if the onset of the disease is more than a week, the effect of using hyperbaric oxygen is poor.
