Correct measuring of metabolic parameters is provided at the FiO

not exceeding 60 %. This is caused by the features of the current method
of measurement.
For the more accurate measurement of metabolic parameters it is recom-
mended before the start of patient’s ventilation to calibrate the O

•
Calculation of metabolic parameters is blocked in the absence of fixing of respiration, during
zero calibration and occlusion of sampling line.
•
When operating with metabolism measurement module remember that explosion of liquid
through sampling line in its measuring path can affect normal operation, so the device has
number of measures for protection against moisture.
•
The main barrier protecting the measuring path from the liquids is water trap for the separa-
tion and condensation of the moisture in the sample and for its accumulation in the special
removable water trap reservoir, which periodically has to be emptied. It takes about 40 hours
for water trap to become full under condition of operating temperature 23°C, patient respira-
tion gas 37° and 100% RH.
Handle the contents of water trap as you would handle any bodily fluid.
Failure to follow this instruction causes infection.
•
During long-term operation of metabolism measurement module under high humidity of the
sample gas sampling line can accumulate a significant amount of condensate, which leads to
the formation of liquid droplets. Large number of droplets can cause occlusion of the measur-
ing path and metabolism measurement module malfunction. In the case of frequent messag-
es about tract occlusion it is usually sufficient to replace the sampling line for a new dry one.
•
After every finishing of operation with metabolism measurement module it is recommended
to disconnect the sampling line from it and run for 5 ... 10 minutes to dry its internal pneumat-
ic system, and to extend the service life of the oxygen sensor.
