Safety Information
WARNING
• Route all tubing away from the patient’s throat to avoid strangulation.
CAUTION
• Remove the airway sample line from the patient’s airway while nebulized medications are being
delivered.
• EtCO
2
values measured from the CO
2
module may differ from those of from the blood gas analysis.
• Avoid mechanical shock to the sidestream CO
2
module configuring the paramagnetic oxygen
sensor.
NOTE
• The CO
2
module automatic suppress physiological alarms until breathing waves have been
detected. Make sure that a patient is properly connected when monitoring with the CO
2
module.

Measurement Limitations
The following factors may influence the measurement accuracy:
■ Leaks or internal venting of sampled gas
■ Mechanical shock
■ Cyclic pressure up to 10 kPa (100 cmH
2
O)
■ Other sources of interference, if any
Measurement accuracy of the sidestream CO
2
module may be affected by the breath rate and inspiration/
expiration (I/E) ratio. Measurement accuracy of the microstream CO2 module may be affected by the breath
rate.For more information, refer to A.15.13CO

Display
The CO
2
numeric and waveform area provide FiCO
2
measurement, EtCO
2
measurement, awRR measurement,
and a CO
2
waveform.
If your sidestream CO
2
module is configured with the oxygen sensor, O
2
waveform and parameters can be
displayed as follows:
(1) CO
