Desflurane:
The presence of desflurane in the exhaled breath at
concentrations greater than 5% will positively bias
Carbon Dioxide values by up to an additional 3
mmHg at 38mmHg.
Xenon:
The presence of Xenon in the exhaled breath will
negatively bias Carbon Dioxide values by up to an
additional 5 mmHg at 38mmHg.
