Chapter 17 Monitoring CO
17.1 Overview
The monitor provides the sidestream and mainstream methods for CO
module, Masimo Sidestream CO
sidestream measuring; Masimo Mainstream CO
module is are used for mainstream measuring. Respironics CO
monitor can automatically identify its sidestream and mainstream modules.
The principle of CO
4.3μm infrared ray. Absorption intensity is proportional to CO
the CO
concentration will compute according to the detecting CO
2
sample.
Sidestream measurement takes a sample of the respiratory gas with a constant sample flow
from the patient's airway and analyzes it with a CO
CO
using the monitor's built-in CO
2
measuring the time interval between detected breaths.
Mainstream measurement uses a CO
into the patient's breathing system.

Safety Information

1
Do not use the device in the environment with flammable anesthetic gas.
2
The device should be used by trained and qualified medical personnel authorized by
EDAN.
3
Nitrous oxide, elevated levels of oxygen, helium, xenon, halogenated hydrocarbons,
and barometric pressure can influence the CO
4
The monitor will be damaged if any pipeline from the CO
inlet /the air outlet is plugged by water or other materials.
5
The accuracy of the CO
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.
8
When using mechanical ventilation, gas compensation should be well set.
Inappropriate setting may cause incorrect measurement result.
