Colonic OMB administration. A Process flow diagram showing the production process for creating OMB via sonication and differential centrifugation (DSPC = distearoylphosphatidylcholine, PEG40S = polyoxyethylene 40 stearate, QA = quality assurance, OMF = oxygen microfoam). B Particle size by both number percent (black) and volume percent (blue) frequency for the OMB samples. C Microscopy image showing the size of the OMB (scale bar = 10 µm). D Schematic showing the colonic delivery of OMB to a smoke inhalation lung injured pig on minimal mechanical ventilation (FiO₂ = 0.21)
