Various methods and systems are provided for flushing a medical gas flow system. In one embodiment, a method for a medical gas flow system comprises: performing a disinfecting cycle of a ventilation gas path comprising a plurality of gas flow passages by: flowing gas from a pressurized gas source of the medical gas flow system to a liquid disinfectant reservoir of a flush module; combining the gas with a liquid disinfectant stored within the liquid disinfectant reservoir to form a disinfectant aerosol; and flowing the disinfectant aerosol through the plurality of gas flow passages.

Heterogeneous azeotrope or azeotrope-like compositions comprising trifluoroiodomethane (CF.sub.3I) and water which may include from about 47.7 wt. % to about 99.0 wt. % trifluoroiodomethane (CF.sub.3I) and from about 1.0 wt. % to about 52.3 wt. % water and having a boiling point between about 18.0° C. and about 19.0° C. at a pressure of between about 58.0 psia and about 60.0 psia. The azeotrope or azeotrope-like compositions may be used to separate impurities from trifluoroiodomethane (CF.sub.3I).
