Carbon dioxide USP is used for insufflation and is often combined with oxygen or air as a respiratory stimulant to promote deep breathing.

Carbon dioxide is an industrial gas used in the pulp and paper industry to control pH levels, enhance pulp yield, and wash brownstock and bleached stock.

Carbon dioxide (CO2) is used as a key cryogenic agent in cooling, chilling and freezing applications — protecting the taste and texture of your food products by maintaining proper temperature control. CO2 also reduces the need for preservatives in packaged products, and is an essential ingredient in carbonated beverages.

A safe alternative to mineral acids, carbon dioxide replaces chemicals used in pH reduction — lowering costs and improving plant safety and flexibility.

Carbon dioxide is most often mixed with argon as a shielding gas used to prevent atmospheric contamination of molten metal in electric arc welding processes.
