26.7 Calibrating AG
Calibrate the AG module every year or when the measured value has a great deviation.
Tools required:
„ Gas bottle, with a certain standard gas or mixture gas. Gas concentration should meet
the following requirements: AA>1.5%, CO2>1.5%, N2O>40%, O2>40%, of which AA
represents an anesthetic agent.
„ T-shape connector
„ Tubing
„ Reservoir bag
Follow this procedure to perform a calibration:
1. In the main menu, select [
Maintenance >>
] → [
User Maintenance >>
] → enter the
required password and then select [
Calibrate AG >>
] from the popup menu.
2. Check the airway and make sure that there are no occlusions or leaks.
‹
Vent the tubing to the air and check if the [
Current FlowRate
] and [
Set FlowRate
]
are approximately the same. If the deviation is great, it indicates that there is an
occlusion in the tubing. Check the tubing for an occlusion.
‹ Block the gas inlet of the tubing. The [
Current FlowRate
] shall fall rapidly and
the system prompts that the tubing is blocked. Otherwise, it indicates that there are
leakages in the tubing. Check the tubing for leakages.
3. Connect the gas bottle, reservoir bag and the tubing using a T-shape connector as shown
in the figure below. Check the airway and make sure there are no leaks.
4. Open the gas valve and vent a certain standard gas or mixture gas into the tubing.
5. In the [
Calibrate AG
] menu, the concentration and flowrate of each measured gas are
displayed
‹ If the difference between the measured gas concentration and the actual one is very
small, a calibration is not needed.
‹
If the difference is great, you should perform a calibration. Select [
Calibrate >>
] to
enter the calibrate menu.
