Anesthetic agents
measurement accuracy ± (0.15 vol% + 5% of reading)
Anesthetic agents display
resolution 0.01% for values between 0…1%
0.1% for values equal or above 1%
Anesthetic agents total system
response time < 3.5 seconds with a 2 or 3m sampling line (< 3.8 for
Hal)
Anesthetic agents rise time Hal, Enf, Iso, Des: < 420 ms with a 3 m sampling line
Hal: < 800 ms with a 3 m sampling line
Hal, Enf, Iso, Des: < 700 ms with a 6 m sampling line
Hal: < 1800 ms with a 6 m sampling line
Hal drift < 0.1 vol%
Enf drift < 0.1 vol%
Iso drift < 0.1 vol%
Sev drift < 0.1 vol%
Des drift < 0.3 vol%
The E-sCAiO, N-CAiO modules automatically identify the anesthetic agent present in
the sampled gas and measure the concentration of the identified agent.
Identification threshold 0.15 vol%
Identification time < 20 s
The E-sCAiO module automatically identifies mixtures of two anesthetic agents present
in the sampled gas and measures the concentrations of the two identified agents.
Identification threshold for the
second agent at 1 MAC of the
first agent: 0.2 vol% +10% of the concentration of the first agent
