Answer:
In 1998, a study was done which compared storing human skin at 4 degrees in either saline, McCoy’s 5A medium, oxygenated McCoy’s and CO₂ McCoy’s.  Skin stored in saline lasted one week, in CO₂ supplemented it lasted less than one week, but in regular McCoy’s or oxygenated McCoy’s, it was viable for 4 weeks. So oxygenation does not improve the viable storage time and CO₂ appears to be detrimental. In this study, a STSG was stored for 5 weeks in regular McCoy’s and still resulted in good take.
