What is the therapeutic mechanism of hyperbaric oxygen? What are the indications?

Brain cells are extremely intolerant to hypoxia, and even a short period of hypoxia can easily cause hypoxic brain damage. Therefore, when brain injury, it is especially necessary to supply sufficient oxygen to promote its repair and brain nerve development. The high pressure oxygen inhaled by the children in the hyperbaric oxygen chamber can triple the oxygen content in the blood, which can effectively improve the hypoxic state of the cells, increase the oxygen supply to the cells, promote the growth of the brain cells, and enable the damaged brain nerves and cells to be repaired. Mechanism of hyperbaric oxygen therapy: improve hypoxia: through improving blood oxygen tension, blood oxygen content and blood oxygen diffusion ability, improve the oxygen partial pressure of brain tissue, cerebrospinal fluid and oxygen storage capacity, so as to improve the hypoxia of brain tissue, correct the tissue acidosis, repair the brain tissue damaged by hypoxia asphyxia. Reduce edema: make intracranial vasoconstriction, reduce vascular bed, reduce intracranial pressure; at the same time, it can improve capillary permeability and extracellular edema, reduce cranial hypertension. Unclogging and promoting the establishment of cerebral microcirculation and collateral circulation, improving the oxygen supply to brain tissues, and facilitating the repair of damaged brain tissues and the recovery of brain functions. Indications:Emergency indications:CO poisoning and other kinds of acute poisoning; gas gangrene, tetanus and other anaerobic infections; gas embolism, decompression sickness; after cardiopulmonary resuscitation caused by various reasons; adjuvant treatment of shock; acute anoxic encephalopathy (cardiac arrest, anesthesia accidents, electrocution, drowning, self-strangulation, etc.); cerebral edema, pulmonary edema (except cardiogenic pulmonary edema); crush injury and crush syndrome; acute spinal cord injury; organ transplantation or replantation. injury; organ and tissue transplantation or reimplantation; drug and chemical poisoning.
