What are the main causes of gas poisoning?
summary
"Gas poisoning" refers to gas, but in life, many people don't know much about this early symptom, and the disease is quite serious when it comes on. In the process of breathing, oxygen (02) combines with hemoglobin (HB) contained in red blood cells to form oxygenated hemoglobin, which is transported to the whole body through blood, and then dissociates from protein when necessary to participate in various reactions. Now I would like to share with you the main causes of gas poisoning?.
What are the main causes of gas poisoning?
First: carbon monoxide can also combine with hemoglobin to form carboxyhemoglobin (COHb). The terrible thing is that its ability to combine with hemoglobin is 300 times that of oxygen! Carbon monoxide dissociates from protein 3600 times slower than oxygen! In other words, if there is carbon monoxide in the inhaled gas, hemoglobin will preferentially combine with carbon monoxide instead of oxygen!
Second: the combination is firm, oxygen has no chance to replace the carbon monoxide on the protein! In the competition between oxygen and carbon monoxide for hemoglobin, carbon monoxide won and oxygen lost! In this way, the consequences are obvious - tissue hypoxia, suffocation of the victim. What's more terrible is that in addition to the sense of asphyxia caused by hypoxia, there is no other specific manifestation of carbon monoxide poisoning.
Third: Although lack of oxygen can lead to dizziness and fatigue, these manifestations are not specific, so they are easy to be ignored, or the poisoned person is sleeping and can not be aware, then the danger may really occur.
matters needing attention
If natural gas and liquefied petroleum gas are not fully burned, carbon monoxide will also be produced. Fortunately, hydrogen sulfide with pungent odor is usually added to natural gas, which is easy to find once it leaks.
