Carbon monoxide poisoning is a product of incomplete combustion of carbon-containing substances and is caused by inhalation through the respiratory tract. Carbon monoxide easily combines with hemoglobin to form carboxyhemoglobin, which causes the hemoglobin to lose its ability and role in carrying oxygen, resulting in tissue asphyxiation, and is toxic to tissue cells throughout the body, especially to the cortex of the brain, which is most severely affected. When people realize that carbon monoxide poisoning has occurred, it is often too late, and the cerebral cortex, which governs human movement, is the first to be paralyzed and damaged, making it impossible for people to achieve purposeful voluntary movement. Light is headache, weakness, dizziness, dyspnea symptoms increase during labor, the patient’s lips will be cherry red, there may be nausea, vomiting, blurred consciousness, deficiency or coma, shock, until death. Carbon monoxide poisoning is short-lived, the carboxyhemoglobin content in the blood is low, the consciousness is clear, the symptoms can disappear quickly after inhaling fresh air and getting out of the poisoned environment, and mild carbon monoxide poisoning can heal itself after getting out of the poisoned environment and breathing fresh air for a certain period of time. The moderate and severe poisoning usually cannot be cured by itself, so it is necessary to go to a medical institution to be treated with oxygen and, if necessary, hyperbaric oxygen. After the treatment of carbon monoxide poisoning, you should also insist on going to the park or balcony in the morning to do deep breathing exercises and play taijiquan to promote recovery.
