In vitro model to compare the oxygen offloading behaviour of dodecafluoropentane emulsion (DDFPe).

AbstractThe aim of this paper was to create an in vitro setup to quantify the oxygen offloading capabilities of dodecafluoropentane emulsion (DDFPe) in a hypoxic environment. Oxygen offloading from DDFPe was characterized under different gaseous environments and under pre-oxygenated conditions. Results of this study showed that (1) oxygen offloading is inversely related to the solubility of the selected sparging gas in saline and (2) both pre-oxygenated and simultaneously oxygenated DDFPe display similar magnitudes of oxygen transport. These results could be applicable to on-going and future studies involving a variety of hypoxic conditions where oxygen delivery might be therapeutically beneficial.
