Liquid ventilation (LV) is a form of mechanical ventilation in which the lungs are insufflated with an oxygen-rich liquid, such as perfluorocarbon, rather an oxygen-rich gas mixture (1). There are two primary types of liquid-assisted ventilation: total liquid ventilation and partial liquid ventilation. In total liquid ventilation, the lungs are filled with perfluorocarbon to a volume equivalent to the lung’s functional residual capacity and a liquid ventilator is used to generate tidal breathing with perfluorocarbon. During partial liquid ventilation, perfluorocarbon fluids are administered into the lungs to act as artificial surfactant for complications, like respiratory distress syndrome, or as a medium for other types of pulmonary dysfunction
