0 to 4 vol% Better than ±0.2 vol% absolute
4 to 9.9 vol% Better than 10% of measured value
Display range for desflurane 0 to 22 vol%
Accuracy for
0 to 8 vol% Better than ±0.4 vol% absolute
8 to 22 vol% Better than 10 % of measured value
Response time t 10...90
at 200 mL/min 350 ms
at 60 mL/min 1 s
Warm-up phase 4 min (accuracy as specified by DIN ISO 11196)

Zero drift Within the ranges specified above
Automatic anaesthetic gas identification The measurement accuracy required by ISO standards
is attained at the latest 4 minutes after switching on the
apparatus. The threshold level for automatic identification
equals 0.15 % by volume.
Anaesthetic gases are identified from a concentration of
0.4 % by volume upwards. If a mixture is present, the gas
with the higher concentration is measured.
SpO2 measurement, optional
(light absorption)
Display range 0 to 100 % SpO2
Accuracy (adults)
between 70 and 100 % SpO2 Better than ±2 % SpO2
between 50 and 70 % SpO2 Better than ±3 % SpO2
between 0 and 50 % SpO2 Not specified
Accuracy (neonates)
between 70 and 95 % SpO2 Better than ±3 % SpO2
between 0 and 70 % SpO2 Not specified
between 95 and 100 % SpO2 Not specified
Actualization time Once per heartbeat
Pulse rate 20 to 250 per minute
Accuracy ±2 per minute
