23.6.1 Preparing to Measure CO

Using Mainstream CO
2
Module
To prepare the CO
2
module for measurement, follow this procedure:
1. Connect the airway adapter to the sensor head.
2. Attach the sensor connector to the CO
2
connector on the mainstream CO
2
module.
3. Zero the sensor after the warm-up is finished. For details, see 23.6.2Zeroing the Mainstream CO
2 sensor
.
4. After the zero calibration is finished, connect the airway as shown below.
5. Make sure that no leakages are in the airway and then start a measurement.
• Be sure to set the barometric pressure properly before using the mainstream CO
2
module. Improper
settings will result in erroneous CO
2
reading.
• Always position the sensor with the adapter in an upright position to avoid collection of fluids in the
windows of the adapter. Large concentrations of fluids at this point will obstruct gas analysis.
• To avoid dead space, place the sensor as close to the patient as possible.
