*: means an extra error should be added in case of gas interference when CO

measurements are performed between 0 to
40mmHg. Inaccuracy specifications are affected by the breath rate and I:E change. The end-tidal gas reading is within
specification for breath rate below 15BPM and I:E ratio smaller than 1:1 relative to the gas readings without breath.

* Accuracy applies for respiration rate up to 80 rpm. For respiration rate above 80 rpm, the accuracy is 4 mmHg or ±12% of
the reading, whichever is greater. for EtCO2 exceeding 18 mmHg. For respiration rate above 60 rpm, the above accuracy
can be achieved by using the CapnoLine H Set for Infant/Neonatal. In the presence of interfering gases, the above accuracy
is maintained to within 4%.
