Medical gas
What are Medical gas?
Medical gases include carbon dioxide, oxygen, nitrogen, nitrogen oxide or air. Medical gases can be use on their own or in combination for therapeutic effect or as a insufflation during surgery.
Medical gases are pharmaceutical gaseous molecules which offer solutions to medical needs. They include traditional gases, like oxygen and nitrous oxide, as well as gases with recently discovered roles as biological messenger molecules including nitric oxide, carbon monoxide and hydrogen sulphide.
Medical gas therapy is a treatment involving the administration of various gases. It has been used in medicine since the use of oxygen therapy. Most of these gases are drugs, including oxygen. Many other gases, collectively known as factitious airs, were explored for medicinal value in the late eighteenth century.
Medical Gas is defined as: NITROGEN, OXYGEN, NITROUS OXIDE and MEDICAL AIR. In addition, Waste Anesthesia Gas Disposal (WAGD) and Medical Vacuum are also considered part of the Medical Gas system.
Medical gases are gases used in medical procedures. Some are used for treatment, some for anesthesia, and some for driving medical devices and tools. There are 7 kinds of gases commonly used: oxygen, nitrogen, nitrous oxide, argon, helium, carbon dioxide, and compressed air.
Nitrous Oxide – A medical gas is used in numerous surgical procedures as both an anesthetic and analgesic. Nitrogen – A medical support gas primarily used for powering surgical tools and other equipment. Carbon Dioxide – Used for less invasive surgeries.
Compressed gas: A large, metal cylinder stores 100% oxygen as a gas under pressure. The cylinder has a regulator to control the flow of oxygen.
The term “designated medical gas” is defined to include oxygen, nitrogen, nitrous oxide, carbon dioxide, helium, carbon monoxide and medical air that meet the standards set forth in an official compendium.
