Safety Information
WARNING
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
2
measurement.
4 The monitor will be damaged if any pipeline from the CO
2
module’s air tube /the air
inlet /the air outlet is plugged by water or other materials.
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.
8 When using mechanical ventilation, gas compensation should be well set.
Inappropriate setting may cause incorrect measurement result.
9 Respironics module is not equipped with automatic air pressure compensation, before
you start the CO
2
measurement for the first time, you must set the correct altitude.
Incorrect altitude settings can cause incorrect CO
2
readings. EDAN EtCO
2
module is
equipped with automatic air pressure compensation, and manual setting is not
required.
10 Leakage in the respiratory system or sampling system may result in a significant low
display of the EtCO
2
value. Always keep all components connected firmly and check
for leaks according to standard clinical procedures.
11 The EtCO
2
reading is not always closely related to the paCO
2
value, especially in
neonatal patients, and patients with pulmonary disease, with pulmonary embolism or
inappropriate ventilation.
12 Don’t measure CO
2
while nebulized medications are being delivered.
13 The CO
2
module temporally stops measuring during zeroing.
NOTE:
1 After the low battery alarm appears, please do not start the CO
2
measurement, or the
monitor may turn off for the low capacity of battery.
2 For disposal of hospital waste such as accumulated fluids, calibration gases,
sampled gases, where not otherwise specified, follow local regulations regarding
disposal of hospital waste.
3 If the measurement or sensor fails, stop measurement before the qualified service
personnel solves the problem.
