8.4.3 Measurement Limitations
Measurement accuracy may degrade due to:
Leakage or internal leakage of the sample gas.
Mechanical shock
Cyclic pressure which is greater than 10 kPa (100 cmH2O)
Other interference source (if available)
8.4.4 Scavenge the Sample Gas
To scavenge the sample gas to the waste gas disposal system, depress the metal chip and then
plug the exhaust tube to the ports marked
(sample gas return to the AGSS) on the
anesthesia machine as shown in the above picture.
WARNING
z When using microstream CO2 module to perform CO2
measurements on the
patient who is receiving or has recently received anesthetic agents, connect the gas
outlet to the waste gas disposal system to prevent the medical staff from breathing
