18.1 General
This chapter offers some relevant data concerning CO
2
monitoring.
The monitor provides the Sidestream and MainStream method for CO
2
monitoring. EDAN EtCO
2
module and Respironics Sidestream CO
2
module are used for sidestream measuring, and
Respironics Mainstream CO
2
module is used for mainstream measuring.
SideStream measurement takes a sample of the respiratory gas with a constant sample flow from
the patient’s airway and analyzes it with a remote CO
2
sensor. You can measure SideStream CO
2
using the monitor’s built-in CO
2
measurement. Respiration rate is calculated by measuring the
time interval between detected breaths.
MainStream measurement uses a CO
2
sensor attached to an airway adapter directly inserted into
the patient’s breathing system.
The CO
2
module can be applied in an operation room, monitor units etc. It can measure the CO
2
partial pressure or concentration of patient Air Way, obtain End tidal CO
2
(EtCO
2
), Fraction of
inspired CO
2
(FiCO
2
), and Air Way Respiration Rate (AwRR), and display CO
2
concentration
waveforms. The parameter symbols displayed on the screen are defined as follows:

AWRR: Air Way Respiration (AwRR) (Resp. times/min)
WARNING
1 CO
2
module shall be avoided from crash and vibration.
2 Do not use the device in the environment with flammable anesthetic gas. For
example, do not use it in the environment where flammable anesthetic is mixed with
air, oxygen or nitrous oxide.
3 The device should be used by trained and qualified personnel who are familiar with
the manual.
4 Nitrous oxide, elevated levels of oxygen, helium, xenon, halogenated hydrocarbons,
and barometric pressure can influence the CO
2
measurement.
5 The accuracy of the CO
2
measurement will be affected by the following reasons: the
airway was highly obstructed; the leakage of air way connection or quick variation of
environment temperature.
6 Follow precautions for electrostatic discharge (ESD) and electromagnetic
interference (EMI) to and from other equipment.
7 Do not place the sensor cables or tubing in any manner that may cause
entanglement or strangulation.
