5.4 Precautions
NOTE: Do not perform SPO2 monitoring and NIBP measurements on the same arm
simultaneously. Obstruction of blood flow during NIBP measurements may adversely
affect the reading of the SPO2 value.
WARNING
•
Check if the sensor cable is in normal condition before monitoring. Do not use
the SPO2 sensor once the package or the sensor is found damaged.
•
Remove the SPO2 sensor from the patient after measurement.
•
As with any medical equipment, carefully route patient cabling to reduce the
possibility of patient entanglement or strangulation. Cables of electrical surgical
equipment should not be winded around that of the SPO2 sensor.
•
Do not put the sensor on extremities with arterial catheter or venous syringe.
If no pulse is found or the reading is unreasonable, first check the patient’s
condition, and then check the sensor installation and connection with the
monitor, finally ask the qualified engineer to check the device and the SPO2
sensor for proper functions.
•
Don’t use the monitor to measure patients whose pulse rate is lower than
30bpm, which may cause incorrect results.
•
Prolonged and continuous monitoring may increase jeopardy of unexpected
change of dermal condition such as abnormal sensitivity, rubescence, vesicle,
repressive putrescence, and so on. It is especially important to check more
frequently the sensor placement of child and patient of poor perfusion or
immature dermographia by light collimation and proper attaching strictly
according to changes of the skin. Check per 2~3 hours the sensor placement and
move it when the skin deteriorates.
•
Make sure no contamination or scar exists in the site where the sensor is placed.
Otherwise, the measured result may be incorrect because the signal received by
the sensor is affected.
•
Please use the SPO2 sensor supplied by the monitor or confined to be used by the
monitor.
•
When used on different patients, the monitor is prone to crossed contamination,
which should be prevented and controlled by the user. Disinfection is
recommended before using the SPO2 sensor on other patients.
CAUTION: SPO2 sensors are precision and fragile. Avoid pressure and knock. Hold the
probe and cable carefully and lightly. If not use it, you should coil up the probe and
cable into a loose circle. If the wire inside the cable is tensely pulled, it may cause
mechanical damage to the probe and the cable.
