Concentration Monitoring Calibrate the AG Module
WARNING: When using AG module to perform AG measurements on the patient who is receiving
or has recently received anesthetic agents, you must connect the gas outlet on the
module to the sample gas return port to return the sample gas to the patient circuit,
preventing the medical staff from breathing in the anesthetic agent.
WARNING: When the Sample Gas Recirculation feature is enabled, please install a breathing
system filter compliant with the ISO 23328-1 and ISO 23328-2 standards on the
patient end.
NOTE: The sample gas recirculation will not impact the measuring precision.
7.11 Calibrate the AG Module
Prepare the following before doing the calibration:
• Gas cylinder: contains a standard or mixed gas. The gas concentration should meet the
following requirements: AA>1.5%, CO
2
>1.5%, N
2
O >40%, O
2
>40%. AA represents an
anesthetic gas.
• T-shape connector
• Breathing tubes
Follow this procedure to perform a calibration:
1. Use the T-shape connector to connect the gas cylinder, gas bag and sampling tube as follows.
