Does repeated disinfection of the e-Flow rapid nebulizer affect in vitro performance?

Repeated disinfection of a nebulizer may modify its performance. During 60 cycles of disinfection with the Nuk steam sterilizer (120 nebulizations), the median volume diameter of tobramycin or colistin, nebulization time and various parameters correlated with the membrane weight of the e-Flow rapid are not modified. Results are similar when tap or purified water is used for washing and disinfection.
