ToxCO Routine Maintenance Guidelines

What are the ToxCO Routine Maintenance Guidelines?

Routine maintenance

See the operating manual for full maintenance instructions. The D-piece requires changing at least every 30 days or if visibly soiled. A reminder will appear on the ToxCO start-up screen. Batteries should be replaced when indicated. They should be removed if the instrument is not likely to be used for some time.


  • The ToxCO should be calibrated with 50ppm CO in air; an onscreen reminder will display every 6 months, however the ToxCO should be calibrated at least once a year.
  • It is recommended that only Bedfont calibration gas is used; the unit may give false readings if not calibrated.


Wipe the external surfaces of the instrument with a product specifically developed for this purpose. Bedfont provides instrument cleansing wipes that contain an antimicrobial liquid. It is recommended that wipes are used once and for one surface only. The device should be cleaned for initial use and after each patient use. NEVER use alcohol or cleaning products containing alcohol or other organic solvents as these vapours will damage the sensor within the instrument. Under no circumstances should the instrument be immersed in or splashed with liquid.
Contact Bedfont or your local distributor for replacements:
  • SteriBreath single-use mouthpiece for use with the D-piece
  • D-piece bacterial filter for use with the SteriBreath mouthpiece
  • OneBreath single-use bacterial filtered mouthpiece
  • Alcohol-free instrument cleansing wipes
