Gas Measurement
The concentration of O2, CO2 and of the anesthetic
agents N
2O, halothane, enflurane, isoflurane,
desflurane, and sevoflurane is measured.
Apollo automatically identifies the anesthetic agent
used and adjusts the measurement and monitoring
of the anesthetic gas concentration to suit the gas
identified.
When no anesthetic agent is applied, the message
“No agent” appears below the O
2

O measurement.

Figure 81. Example of Calibration MessagesCalibration
The gas measuring module is calibrated
automatically when the workstation is started and
then every two hours after that.
O
2
calibration is performed parallel to the gas
measuring module every eight hours.
During calibration, messages informing the user
about the calibration appear on the screen (1 and 2
in Figure 81), and the measurement values are
replaced with the word “CAL” (3 in Figure 81).
CO2 and O2
The CO2 and O2 concentrations are side-stream
measured, thus delaying an indication of the real-
time values by approximately four seconds. The
displayed CO
2 and O2 curves are not synchronized
with the pressure and flow curves.
If apnea occurs, the display for etCO
2 is replaced by
the message "Apnea". The apnea time [min:sec] is
displayed instead of the measured value.
Anesthetic agents
The anesthetic agents are side-stream measured in
the same way as CO
2 and O2.
WARNING !
The presence of aerosols in the breathing
circuit should be avoided, as the displayed
agent concentrations and/or the water trap
membrane may be affected.
The presence of organic cleaning agents or
gases contaning haloalkanes (e.g., CFC) will
impair the accuracy of the integrated gas
analyzer.
