Presentation of fresh-gas utilisation as a bar graph with the
three ranges Excess, Efficient and Deficit.
Loops (optional)?
Two pairs of measured values which are plotted against
one another appear as a loop in the ventilation cycle:
the PAW-V loop and the V-Flow loop.
Gas measurement
The concentration of 02, CO2 and of the anaesthetic agents
N20, halothane, enflurane, isoflurane, desflurane and
sevoflurane is measured.
Calibration
The gas measuring module is calibrated automatically when
the workstation is started and then every two hours after that.
The O2 sensor is calibrated when the workstation is started
and then every eight hours after that.
Calibration is performed parallel to the gas measuring module
every 2 hours during consumption-free O2 measurement.
CO2 and O2
The CO2 and O2 concentrations are side-stream measured,
thus delaying an indication of the reaktime values by approx.
2 seconds. The pressure (and flow) curve, CO2 and O2 curves
displayed are not synchronized.
If an apnoea occurs, the display for etCO2 is replaced by the
message "Apnoea". The apnoea time [min:sec] is displayed
instead of the measured value.
