; becomes primary agent if expiratory xMAC is
more than 0.2 MAC above former primary agent.
Cross-sensitivity None referred to alcohol (<3000 ppm), acetone (<1000 ppm), methane,
water vapor, NO, and CO
Drift of measurement accuracy Compensated by cyclic zeroing. Zeroing is performed automatically and
with ambient air. This means there is minimal change to the gas
concentrations in the breathing circuit.
