Drift of measurement accuracy
• The respiration rate limit for accurately measured end-tidal values is < 60 breaths/minute for I:E =
1:1, < 40 breaths/minute for I:E = 1:2 and < 30 breaths/minute for I:E = 1:3.
• The accuracy of the gas measurements may be affected if the Ethanol concentration is higher than
0.1%, the Methane concentration is higher than 1% or the Acetone concentration is higher than 1%.
• The partial pressure and the percentage volume of CO
the amount of water vapor in the breathing gas. A partial H
automatically compensated for by the analyzer. Higher H

Primary anesthetic agent identification
A primary anesthetic agent will be identified by the gas analyzer if the concentration is higher than 0.4%
(ISO accuracy) or 0.15% (Full accuracy)
