Instructions for use Zeus Infinity Empowered SW 2.n
Anesthetic gas measurement (infrared spectroscopy)
Measuring ranges of the anesthetic gases:
Halothane Measuring range: 0 to 8.5 Vol.%
Enflurane Measuring range: 0 to 10 Vol.%
Isoflurane Measuring range: 0 to 8.5 Vol.%
Sevoflurane Measuring range: 0 to 10 Vol.%
Desflurane Measuring range: 0 to 20 Vol.%
Accuracy of anesthetic gas measurement: ±(0.2 Vol.% + 15 % of the measured value) in ac-
cordance with ISO 21647
Drift of measuring accuracy is compensated by cy-
clic zeroing.
Resolution of anesthetic gas measurement: 0.1 Vol.%
N
2O Measuring range: 0 to 100 Vol.%
Accuracy: ±(2.0 Vol.% + 8 % of the measured
value) in accordance with ISO 21647
Resolution: 1 Vol.%
xMAC Measuring range: 0 to 9.9 xMAC
Resolution: 0.01 xMAC
Display: based on the expiratory measured values
Alarms: based on the inspiratory measured values
All gases
Anesthetic gas detection Automatic
Primary gas: from 0.3 Vol.%
Secondary gas: from 0.4 Vol.%
Cross sensitivity
3 ‰ alcohol

100 ppm NO or CO
Water steam saturated at 37 °C
Distortion <0.2 Vol.% for anesthetic gas, CO
2, and
N2O measurement.
Distortion <1 Vol.% for O
2 measurement.
