A.8.7.4 The effects on CO
2
measuring values caused by the interfering gases
 BLT TL _ Si & BLT CPT
The accuracy of CO
2
is affected by interfering gases and water vapor. For example,
N2O, a halide-containing anesthetic gas can raise the CO
2
reading (about 2%-10%), and
helium and oxygen can reduce the CO
2
reading (1%-10%), so in the presence of
interfering gas, the user should send relevant command to the module (the instrument’s
compensation menu to adjust the interference gas data), so that the module (instrument)
can meet the nominal accuracy requirements.
