The patient wore an air fit medium mask from resmed.We have two different lot numbers for that model and size.I sent one of each to microbiology.One came back no growth after four days, but the other one (lot #1143645) came back growth of sphinomonas paucimobilis (pseudomonas paucimobilis).I have removed the remaining air fit medium masks with that lot number.This was a voluntary test of the medical device and was found to have growth of sphingomonas paucimobilis (pseudomonas paucimobifis) on the product.
