Because of the difference in pressure your lungs feel in space or underwater, liquid ventilation could be useful while exploring the far reaches of the universe or the depths of the ocean.
由于您的肺部在太空或水下感受到的压力不同，液体通气在探索宇宙深处或海洋深处时可能很有用。
英语百科
Liquid breathing
（重定向自Liquid ventilation）
Liquid breathing is a form of respiration in which a normally air-breathing organism breathes an oxygen-rich liquid (such as a perfluorocarbon), rather than breathing air.
Perfluorochemical (perfluorocarbon) molecules have very different structures that impart different physical properties such as respiratory gas solubility, density, viscosity, vapor pressure, and lipid solubility. Thus, it is critical to choose the appropriate PFC for a specific biomedical application, such as liquid ventilation, drug delivery or blood substitutes. The physical properties of PFC liquids vary substantially; however, the one common property is their high solubility for respiratory gases. In fact, these liquids carry more oxygen and carbon dioxide than blood.
