Medical gas


Medical gases are gases used in medical procedures, some for treatment, some for anesthesia, and some for driving medical equipment and tools. Commonly used gases are: oxygen, nitrogen, nitrous oxide, argon, helium, carbon dioxide and compressed air.


Use of medical gases

Oxygen: The molecular formula of oxygen O2. It is a strong oxidant and combustion improver. When high-concentration oxygen encounters oil, it will undergo strong oxidation reaction, produce high temperature, and even burn and explode. However, oxygen is also the most basic substance for life-sustaining. Medically used to supplement oxygen in hypoxic patients, direct inhalation of high-purity oxygen is harmful to the human body, and the oxygen concentration for long-term use generally does not exceed 30% to 40%. Ordinary patients take oxygen through a humidified bottle; critically ill patients take oxygen through a ventilator. Oxygen is also used in high-pressure warehouses for the treatment of diving diseases, gas poisoning, and for drug atomization.


Nitrous oxide: The molecular formula of nitrous oxide is N2O, which is a colorless, mellow, sweet-smelling gas. After a small amount of inhalation, facial muscles will be paralyzed, and a smiley expression appears, which is called "laughing."

Nitrous oxide is inert and non-corrosive at room temperature. Nitrous oxide will decompose into nitrogen and oxygen at a temperature higher than 650 ° C, so it has a combustion-supporting effect. At high temperatures, when the pressure exceeds 15 atm, it will cause oil to burn.

After a small amount of inhalation of laughter, there is anesthesia and analgesic effect, but a large amount of inhalation can cause suffocation. Medically, a mixture of laughing gas and oxygen is used as an anesthetic, and the patient is inhaled by a closed method or a ventilator for anesthesia.


Carbon dioxide: Carbon dioxide molecular formula CO2, commonly known as carbonic acid gas. Medically, carbon dioxide is used to inflate the abdominal cavity and knot for laparoscopy and fiberoptic colonoscopy. In addition, it is also used in laboratory culture of bacteria.

Carbon dioxide can be made into dry ice after being pressurized and cooled. Medical dry ice is used in cryotherapy for the treatment of cataracts and white blood vessel diseases.


Argon, helium: Argon gas type Ar helium The molecular formula He, they are a colorless, odorless, non-toxic inert gas, medically used for surgical instruments such as argon knives and helium knives.


Compressed air: Compressed air is used to transmit power to oral surgical instruments, orthopedic instruments, ventilators, and the like.


Nitrogen: Nitrogen molecular formula N2, which is a colorless, odorless, non-toxic, non-combustible gas, is inactive at room temperature, does not chemically react with ordinary metals, and is used to drive medical equipment and tools medically.
