Anesthetic agent limit Primary anesthetic agent
In full accuracy mode: 0.15%,
In ISO accuracy mode: 0.3%
Secondary anesthetic agent:
In full accuracy mode: 5% of primary agent if primary agent is greater than
10%, 0.3% if primary agent is less than or equal to 10%.
Data sample rate 25 Hz
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; Add ±6%REL to
inaccuracy for HAL and O
2
for breath rate larger than 15 BPM; Add ±6%REL to inaccuracy for all gases for breath rate larger
than 30 BPM (inaccuracy for HAL and O
2
are unspecified in this case); inaccuracy is unspecified for breath rate larger than 60
BPM.
