Sampling rate:
Maximum sampling line length:
Sampling delay:
Total system response time:
Warm-up time:
Autozeroing interval:
Automatic compensation for barometric pressure.
Gas values are measured in ATPD conditions (ambient temperature and pressure, dry). When CO2 is
displayed as a partial pressure (kPa, mmHg), the value can be alternatively shown as wet (BTPS, body
temperature and pressure saturated).
Non-disturbing gases are those with a maximum effect on the CO
effect is valid for specific concentrations shown in parentheses of the non-disturbing gas:
Ethanol C
Acetone (<0.1%)
Methane CH
Nitrogen N
water vapor (0 to 100%)
Dichlorofluoromethane (<1%)
Tetrafluoroethane (<1%)
Disturbing gases and their effect on the CO
reflect the effect of specific concentrations (shown in parentheses) of an individual disturbing gas and
should be combined when estimating the effect of gas mixtures:
Halothane (4%) increases < 0.3 vol%
Isoflurane(5%) increases < 0.4 vol%
Enflurane(5%) increases < 0.4 vol%
Desflurane(24%) increases < 1.2 vol%
Sevoflurane(6%) increases < 0.4 vol%
Helium (50%) decreases < 0.3 vol%
