Liquid ventilation refers to the medical technique of supplying oxygen to the lungs by filling them with a liquid, rather than the conventional use of air. This innovative approach has shown promising potential for critically ill patients, particularly newborns suffering from respiratory distress syndrome or adults with acute lung injury. Other terms synonymous with liquid ventilation include liquid-assisted ventilation, oxygenated liquid ventilation, or perfluorocarbon ventilation. By employing these alternative expressions, healthcare professionals can efficiently communicate and share knowledge about this cutting-edge respiratory therapy. As research continues to explore the benefits and applications of liquid ventilation, its synonyms contribute to a comprehensive understanding of this life-saving procedure.
