Anesthesia vaporizer manufacturers recommend calibrating your equipment on a regular basis. A common range is from one to three years depending on your model. Why service your vaporizers?
To ensure the vaporizer is delivering the correct required concentration of anesthetic agent it needs to be professionally serviced.
Unserviced vaporizers have the potential to leak agent into the O.R. atmosphere causing a potential health hazard.
Recommended Service Time
The primary standard for re-calibration / certification is the manufacturer recommendation. If no such recommendation exists then the anesthetic agent delivery should be validated annually or any time the vaporizer has not been in service for more than one year. If the verified delivery is ± 10% out of calibration, the unit should be serviced by a professional service center.
Indications for Service
Discoloration (yellowish-brown) in the "Fill" sight glass of a vaporizer may be an indicator for the need for service by an authorized service center. Other indicators might include cracked or damaged hoses, sticking valves or knobs, patients not responding (as anticipated) to the level of anesthesia provided.
