All external parts of the Vitalograph lung monitor require
cleaning
, i.e. the removal of
visible particulate contamination. The parts of the device that make up the flowhead,
which comes into contact with the breath of the subjects being tested, also require
disinfecting
. This device is not designated as a ‘sterile’ device.
Definitions of cleaning and disinfection are as defined in “Sterilization, Disinfection and
Cleaning of Medical Equipment:
Guidance on Decontamination from the Microbiology Committee to Department of
Health Medical Devices Directorate, 1996”.
Recommendations for chemical disinfectants are derived from the PHLS publication
“Chemical Disinfection in Hospitals” 1993.
