In medicine, gases play a fundamental role and are used in emergency situations or for therapeutic or diagnostic purposes. Its applications are as diverse and complex as the composition of medical gases, which are generally classified as medicines or medical devices depending on their application and their mechanism of action.
Know about the gases used in the medical sector
Medical gases are closely related to medical processes, as they are used in many areas of modern medicine - surgery, cryosurgery, in vivo, anesthesiology, pulmonology, endoscopy, diagnostics, calibration of medical equipment, and many others. The scope of gases is very wide and can be divided into two main groups depending on the state of aggregation in which the gas is located, that is, gaseous and liquid.
The following gases are used in medicine:
- medical gaseous oxygen;
- oxygen liquid medical;
- cyclopropane;
- nitrous oxide.
- synthetic air;
- compressed air;
- liquid nitrogen;
- argon gaseous;
- helium gas A;
- helium gaseous B;
- liquid helium;
- carbon dioxide (carbonic acid) food;
- carbon dioxide (carbon dioxide) HF;
Therapeutic gases and gas mixtures for stimulating respiration are the most demanded and important group of medical gases. The composition of artificial respiratory medical gases can be adapted to specific circumstances and requirements. So, in medicine, such gaseous mixtures are used:
- a mixture of oxygen and carbon dioxide;
- a mixture of helium and oxygen;
- excimer gas mixture;
- a mixture containing ethylene oxide.
Medical gases are needed not only for diagnostic purposes and anesthesia; they are also used in clinical research and research laboratories.

Creation of a centralized gas supply system
District gas supply systems (PGS) are generally based on the principles of transporting large volumes of gas, storing gas on-site in special containers, and distributing gas from large gas storage facilities to end users. Gas from the producer can be delivered to consumers in a liquefied form, mainly through the use of cryogenic systems, or in a compressed gaseous form, usually using steel cylinders or cylinder bundles. After the installation of the CCG at the place of use and the start of its operation, the gas comes from a source (stationary or mobile cryogenic tank with an evaporator - gasifier, a balloon bundle with a ramp, cylinder, or special container) through a high-pressure manifold with a pressure Medical Oxygen Flowmeter, where the inlet pressure of the supply system is reduced to a level acceptable for entry into the gas distribution system (GDS). The range of works on the creation of a centralized gas supply system (SCG) can be divided into several stages:
- Creation of a gas supply network project;
- Project completion;
- Assembly of the medical gas supply system;
- Launch and setup;
- Technical support of medical gas supply systems.
You must also install Oxygen Regulators to control the amount of oxygen to be supplied.Medical gas delivery systems require increased attention to safety. To prevent danger, control devices such as Oxygen Flow Meter and shut-off valves are installed in gas pipelines to quickly disconnect the building from the gas source in the event of an explosion hazard.
