What role does medical carbon dioxide gas intervention play

Medical gases are gases used in medical procedures, some for treatment, some for anesthesia, and some to power medical equipment and tools. Commonly used gases are: oxygen, nitrogen, dinitrogen oxide, argon, helium, carbon dioxide and compressed air. Uses of Medical Gases Oxygen: Oxygen has the molecular formula O2. it is a strong oxidizing agent and accelerant, and high concentrations of oxygen will undergo a strong oxidation reaction when it encounters fats and oils, generating high temperatures, and even combustion and explosions. However, oxygen is also the most basic substance to maintain life, medical treatment is used to supplement oxygen to patients with hypoxia, direct inhalation of high purity oxygen is harmful to the human body, long-term use of oxygen concentration is generally not more than 30% ~ 40%. Ordinary patients inhale oxygen through humidified bottles; critically ill patients inhale oxygen through ventilators. Oxygen is also used in the hyperbaric chamber for the treatment of diving sickness, gas poisoning and for drug atomization. Nitrous oxide: nitrous oxide molecular formula for N2O, it is a colorless, good-smelling, sweet-smelling gas, a small amount of inhalation, facial muscles will spasm, the appearance of laughter, solid called "laughing gas". Nitrous oxide is inactive and non-corrosive at room temperature. Nitrous oxide is decomposed into nitrogen and oxygen at a high temperature of over 650℃, so it has a flammable effect, and at high temperature, the pressure exceeds 15 atmospheres, which will cause the burning of fats and oils. A small amount of inhalation of laughing gas, anesthesia and pain relief, but a large number of inhalation will cause people to asphyxiate. The mixture of nitrous oxide and oxygen is used as an anesthetic in medical treatment, and is inhaled through a closed circuit or a ventilator to anesthetize the patient. Carbon Dioxide Carbon dioxide has the molecular formula CO2 and is commonly known as carbonic acid gas. Medically CO2 is used for abdominal and conjunctival insufflation for laparoscopy and fiberoptic colonoscopy. In addition, it is used in laboratories to culture bacteria. Carbon dioxide is pressurized, cooled, and can be made into dry ice. Medical dry ice is used in cryotherapy for the treatment of cataracts and white blood vessel disease. Argon, helium argon molecular formula Ar helium molecular formula He, they are a colorless, odorless, non-toxic inert gases, medical used in argon knife, helium knife and other surgical instruments. Compressed Air Compressed air is used to transfer power for oral surgical instruments, orthopedic instruments, ventilators, etc.. Nitrogen: the molecular formula of nitrogen N2, it is a colorless, odorless, non-toxic, non-combustible gas, inactive at room temperature, does not have a chemical reaction with the general metal, medical used to drive medical equipment and tools.
