上世纪６０年代，在小鼠身上就进行过这类实验，所使用的液体称为全氟碳化物（PFC），它能保证在肺中交换氧气和二氧化碳。小鼠完全浸泡在这种液体中，照样能正常呼吸。近年来这种通过液体进行呼吸的方法被越来越多地引入欧美的医疗实践中，以帮助那些有严重呼吸障碍的人（外伤 In the 1960s, such experiments were performed on mice. The fluid used was called perfluorocarbon (PFC), which ensures the exchange of oxygen and carbon dioxide in the lungs. The mice were completely immersed in this liquid and they were able to breathe normally. In recent years, this method of breathing through liquids has been increasingly introduced into medical practice in Europe and the United States to help those with severe respiratory disorders (traumatic injuries).
