WARNING
8 Do not store the CO
2
Module at temperatures less than -40 ºF (-40 ºC) or greater
than 158 ºF (70 ºC). Do not operate the CO
2
Module at temperatures less than 32 ºF
(0 ºC) or greater than 104 ºF (40 ºC).
9 The patient monitor will be damaged if the water quantity in the water trap reaches
the limit.
10 The monitor will be damaged if any pipeline from the CO
2
module’s air tube/air
inlet/air outlet are plugged by water or other materials.
11 When using mechanical ventilation, gas compensation should be well set.
Inappropriate setting may cause incorrect measurement result.
12 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.
13 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.
14 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.
15 Don’t measure CO
2
while nebulized medications are being delivered.
16 The CO
2
module temporally stops measuring during zeroing.
NOTE:
1. After the Low battery alarm is activated, please do not start the CO
2
measurement, or
the monitor may be turned 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.
18.2 Monitoring Procedure
The principle of CO
2
measurement is primarily based on the fact that CO
2
molecule can absorb
4.3μm infrared ray. Absorption intensity is proportional to CO
2
concentration of patient sample,
the CO
2
concentration will compute according to the detecting CO
2
absorption intensity of patient
sample. The relation between partial pressure and percentage of CO
2
concentration is given
below:
P (mmHg) = Percentage (%) × Pamp (Ambient Pressure)
