 Severe respiratory failure often necessitates oxygenation support using ventilators or artificial lungs. However, the recent pandemic exposed the limited availability and accessibility of such devices, emphasizing the need for alternative respiratory support methods utilizing different organs. Drawing inspiration from the intestinal breathing mechanism observed in unique aquatic organisms like loaches, we investigated the potential of enteral ventilation in mammalian species. In our experimental studies, we delivered oxygenated perfluorodecalin intra-rectally to mice and pigs experiencing severe hypoxia while under controlled mechanical ventilation. Through longitudinal blood gas monitoring, we observed that enteral ventilation effectively oxygenated the animals by utilizing venous routes, thus preventing fatal respiratory failure. These findings represent the first experimental evidence supporting the concept of enteral ventilation and pave the way for further clinical development toward its application in humans. This article outlines the concept of enteral ventilation technology and discusses our ongoing translational efforts. Our goal is to develop a new, simpler, less invasive, and adjunctive method of oxygenation to address respiratory failure in humans.
