Anaesthetic Gas Monitoring

This tube is suitable for passive or active monitoring of Nitrous Oxide (N2O) and other anaesthetic gases in the workplace. This tube can be worn close to the breathing zone for up to 8 hours or  exposed in areas adjacent to the gas administration for the personal exposure assessment.  Many professionals, including doctors, nurses, dentists and vets use anaesthetic gases on a regular basis. Continuous exposure to these gases can be harmful, so monitoring of both personal exposure and ambient concentrations is important.


Potential implications of continual worker exposure to anaesthetic gases:

  • Respiratory irritation, e.g., coughing.
  • Dizziness
  • Nausea
  • Reproductive effects.
