Update: Ralstonia species associated with Vapotherm oxygen delivery devices--United States, 2005.
This report updates information on Ralstonia species associated with Vapotherm oxygen delivery devices (Vapotherm Inc., Stevensville, Maryland). CDC has obtained new information from a test developed by CDC and performed by The Children's Hospital of Philadelphia (Pennsylvania) to assess the efficacy of the new chlorine dioxide disinfection protocol recommended by Vapotherm. Although limited, this information suggests that the new protocol for disinfecting Vapotherm devices and cartridges might not achieve sustained bacterial control in certain situations. At this time, the optimal protocol to disinfect machines and cartridges that might contain very heavy biofilms is not known.
