Comparison of P. aeruginosa colonization on OCT coated versus uncoated tracheostomy tubes. Mean cfu concentration [log] after standardized contamination with P. aeruginosa before any reprocessing [T1], after 5 rounds of reprocessing [T2] and an additional 5 reprocessing procedures [T3]. OCT coated tracheostomy tubes are represented by gray bars, uncoated tubes by white bars.
