2. The use of different SpO
2
sensors
There are a number of different SpO
2
Sensors for use with this monitor.
Please see brochure or listing at rear of Manual for details.
PLEASE NOTE
: when SpO
2
is not being monitored the probe should be
disconnected from the monitor to save battery life, or the two windows
of sensor should be kept face to face, otherwise the light window will remain
operational and the photoplethysmogram wave will be disordered and the
screen will display “
FAIL SEARCH
”.
V. Notice
1. Caution:
Under conditions of electromagnetic influence, for example: electrosurgical
devices, MRI, CT etc. they may cause incorrect operation.
This device is not MRI/CT Compatible.
The filter/water trap T3 should be taken off and replaced when it is nearly
full of water, otherwise water ingress may cause irreversible damage for IR
measurement detector cell. Be sure that the collecting pipe is not occluded
to avoid stressing the inner sampling pump reduction of pump life.
2. Attention:
other important information.
1) CO
2
:
The approved sampling lines provided by or specified by the manufacturer
or distributor, shall be used, otherwise readings may be inaccurate.
Fast changes in ambient Temperature may cause inaccuracy and in this
instance the Display will show “TEMP IMBALANCE”.
The measured data may be influenced by different kinds of anaesthetic gases.
If it is required to calibrate interference gases please refer to Appendix 2.
Any circumstances of blocking of the gas sampling line, such as bending,
folding, contamination blocking the sampling tube and filter or water trap etc.
may lead to inaccurate measurement.
Serious respiratory conditions leading to exhaled CO
2
concentration being
extremely high or low, e.g. EtCO
2
lower than 0.5% or higher than 11%, may
generate inaccurate measurement.
Any air leaks in the sampling line circuit will seriously influence accuracy
of data measured and waveform shape.
2) Oximeter:
The monitor’s measurement of SpO
2
may be influenced by strong ambient
light. Therefore the user should unplug the SpO
2
Sensor when it is not being
used.
Accuracy of oximeter readings will be influenced if there is imaging dye
in the blood or if CO has been inhaled by the Patient.
