9.2 Precautions During SpO
2
/PR Monitoring
WARNING
1 Verify sensor cable fault detection before beginning of monitoring phase. Unplug the
SpO
2
sensor cable from the socket, the screen will display the error message SpO
2
SENSOR OFF and the audible alarm is activated.
2 If the SpO
2
sensor can not work properly, please reconnect the sensor or change a
new one.
3 Do not use the sterile supplied SpO
2
sensors if the packaging or the sensor is
damaged and return them to the vendor.
4 Prolonged and continuous monitoring may increase the risk of unexpected change of
dermal condition such as abnormal sensitivity, rubescence, vesicle, repressive
putrescence, and so on. It is especially important to check the sensor placement of
neonates and patients of poor perfusion or immature dermogram by light collimation
and proper attaching strictly according to changes of the skin. More frequent
examinations may be required for different patients.
5 Tissue damage may be caused by incorrect application or prolonged measurement
duration using the sensor (more than 4 hours). Inspect the sensor periodically
according to sensor user manual.
6 Neonate SpO
2
sensor can only be used as required, less than 20min at a time.
7 The sensor complies with the ISO 10993-1 for biocompatibility.
NOTE:
1 Make sure the nail covers the light window;
2 The wire should be on the backside of the hand;
3 Hand should not be too cold when measuring, and the nail polish should be cleaned
before measuring, or the data accuracy may be affected.
4 SpO
2
waveform is not proportional to the pulse volume.
5 The accuracy of SpO
2
has been verified by clinical tests according to ISO9919. The
monitor can only be used for SpO
2
measurement, not for accuracy assessment of
other device.
6 A functional tester cannot be used to assess SpO
2
accuracy.
