The main mechanism of hyperbaric oxygen therapy for carbon monoxide poisoning is mainly to improve the concentration of blood oxygen in the patient’s body, which may relieve the condition of carbon monoxide poisoning. When the patient has carbon monoxide poisoning, the hyperbaric oxygen chamber can be used for treatment, and its main therapeutic mechanism is to promote the combination of oxygen and hemoglobin to increase the concentration of oxygen in the blood, accelerate the rate of carbon monoxide contouring, and increase the concentration of oxidized hemoglobin in the body, which can make the whole body and the lack of oxygen in the brain tissue state be effectively improved, and can alleviate the condition of carbon monoxide poisoning. If the patient is diagnosed with carbon monoxide poisoning, it is necessary to immediately get out of the carbon monoxide environment, keep the airway open, and immediately carry out oxygen therapy or hyperbaric oxygen chamber treatment, so as to improve the hypoxic state as soon as possible. Hyperbaric oxygen therapy needs to be carried out under the guidance of professional physicians, please do not treat yourself to avoid delaying the condition.
