Patient Monitor User Manual
Chapter 19 Monitoring AG
19.1 Overview
The monitor uses ISA sidestreasm gas analyzer (hereinafter called ISA analyzer), Dräger AG
sidestream Minimodule (hereinafter called Dräger Minimodule), EDAN G7 sidestream
(hereinafter called G7 Module) and IRMA mainstream module (hereinafter called IRMA module)
to monitor the anesthetic gas which can be used to measure the gases of adult, pediatric and
neonatal patients during anesthesia, recovery and respiratory care. And the anesthetic gas
includes Halothane (HAL), Isoflurane (ISO), Enflurane (ENF), Sevoflurane (SEV), Desflurane
(DES), N
O, and O
2
MFM-CMS.
19.2 Safety Information
19.2.1 Safety Information for G7 Module
1
G7 Module is not designed for MRI environments.
2
Do not use the device in the environment with flammable anesthetic gas.
3
The device should be used by trained and qualified medical personnel authorized by
EDAN.
4
Nitrous oxide, elevated levels of oxygen, helium, xenon, halogenated hydrocarbons,
and barometric pressure can influence the AG measurement.
5
The monitor will be damaged if any pipeline from the AG module's air tube /the air
inlet /the air outlet is plugged by water or other materials.
6
The accuracy of the AG 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.
7
Follow precautions for electrostatic discharge (ESD) and electromagnetic interference
(EMI) to and from other equipment.
8
The use of authentic EDAN anesthesia sample lines is strongly recommended, as
other sample lines with an incorrect length and/or diameter may lead to erroneous
agent concentration readings.
9
Since a successful zeroing requires the presence of ambient air (21% O
CO
), ensure that the module is placed in a well-ventilated place. Avoid breathing
2
near the module before or during the zeroing procedure.
10
The module is intended only as an adjunct in patient assessment. It must be used in
conjunction with other assessments of clinical signs and symptoms.
11
Exhaust gases should be returned to the patient circuit or a scavenging system.
12
Too strong positive or negative pressure in the patient circuit might affect the sample
flow.
