asphyxiating gas

1. Simple asphyxiating gas itself has very low toxicity or is an inert gas, but its high content in the air greatly reduces the relative content of oxygen, causing the partial pressure of oxygen in arterial blood to drop, causing the body to suffocate due to hypoxia. Such as nitrogen, methane, carbon dioxide, water vapor, etc. 2. Chemical asphyxiating gases can mainly produce special chemical effects on blood or tissues, impeding oxygen transportation and tissue utilization of oxygen, causing tissue hypoxia throughout the body and causing severe poisoning. Commonly found in industrial production are carbon monoxide, cyanide and hydrogen sulfide. They are divided into two subcategories according to different poisoning mechanisms.
