Breathing gas - Common diving breathing gases

Air is the most common and only natural breathing gas. Other artificial gases, either pure gases or mixtures of gases, are used in enclosed breathing environments such as SCUBA equipment, recompression chambers, submarines, space suits and anaesthetic machines. A safe breathing gas has three essential features: it must contain sufficient oxygen to support the life, consciousness and work rate of the breather. it must not contain harmful gases. Carbon monoxide and carbon dioxide are common poisons in ...

Breathing gas - Oxygen. Oxygen (O2) must be present in every breathing gas. This is because it is essential to the human body's metabolic process, which sustains life. The human body cannot store oxygen for later use as it does with food. If the body is deprived of oxygen for more than a few minutes, unconsciousness results. The tissues and organs within the body (notably the heart and brain) are dama ...

Many gases are not suitable for use in diving breathing gases. Here is an incomplete list. Breathing gas - Argon. Argon (Ar) is an inert gas that is more narcotic than nitrogen, so is not suitable as a diving breathing gas. It is used for dry suit inflation because of its good thermal insulation properties. Argon is much more expensive than air. Breathing gas - Carbon dioxide. Carbon dioxide (CO2) is produced by the metabolism of the human body and causes carbon dioxide ...
