Bad air and the presence of dizziness is mainly due to the decrease in oxygen concentration in the air causing ischemia and hypoxia in the tissues, resulting in insufficient blood and oxygen supply to the brain causing dizziness. If there are obvious symptoms of dizziness, it is recommended that you need to get out of the air environment of harmful or toxic gases, and you can take oxygen under the guidance of a physician to improve the oxygen concentration in the organism and improve the blood supply and oxygen supply to the brain. Pay attention to rest and relieve tension to avoid aggravation of dizziness. If there is severe nausea, vomiting, impaired consciousness or obvious emotional and mental abnormalities, the possibility of gas poisoning cannot be ruled out and it is necessary to visit the emergency department promptly. If there is carbon monoxide poisoning, it is recommended that timely hyperbaric oxygen therapy be performed.
