Cerebral hypoxia. What caused it?

The causes of hypoxia are very many, consider the environment caused by hypoxia, such as carbon monoxide poisoning, but also pay attention to the patient's lungs caused by bad, such as chronic bronchitis, emphysema, pulmonary bullae, all affect the lung ventilation function. Patients with poor heart function are also likely to cause ischemia, hypoxia, because oxygen is exchanged through blood circulation, so the heart is not good will also affect the human blood supply and cause hypoxia symptoms. For patients with hypoxia, oxygen should be given in time, or hyperbaric oxygen treatment should be carried out if necessary, and the elimination of the causes of hypoxia is also very critical. Therefore, specific treatment should be carried out according to the specific causes of hypoxia, and oxygen and hyperbaric oxygen should be used to alleviate the state of hypoxia.
