This is a strong example of a title that simultaneously make me want to click on it but made me afraid to do so. In the end I chickened out.
>Intra-rectal delivery of a liquid form of O2 known as conjugated perfluorocarbon, a compound historically used in clinics for liquid ventilation through airway administration, is highly tolerable and efficacious in ameliorating severe respiratory failure. Thus, by repurposing the distal gut as an accessary breathing organ, enteral ventilation therapy offers an alternative paradigm as an adjunctive means to patients who are in critical need of respiratory support.
Calling PFCs "a liquid form of O2" is like saying carbonated water is "a liquid form of CO2".
