Liquid breathing

Liquid breathing is when an organism that usually breathes air breathes a special liquid rich in oxygen. This liquid can exchange carbon dioxide ( ${\ce {CO2}}$ ) and oxygen, like perfluorocarbon ( ${\ce {PFC}}$ ).^[1]

It should possess some properties like dissolving of gases in it, appropriate viscosity and stability.^[2] Correct selection of PFC is highly important based on medical application, whether respiration or drug delivery or blood substitution is required. PFC liquids can carry more oxygen and more ${\ce {CO2}}$ as compared to blood.^[3]

Liquid breathing could save the life of a person who has sustained serious injury to their lungs or heart. Liquid breathing has also been proposed for use in deep diving^[4]^[5] It could also be used for deep-sea diving and space travel.^[6] But there is no standard way to use it yet.
