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

measurements are
performed between 0-40mmHg.
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.
