Vigorous movement of the paent, strong ambient light, or extreme electro-surgical interference may also aect
the SpO
2
measuring accuracy.
DO NOT stare at the light of SpO
2
sensor (infrared is invisible) when switch it on, for the infrared may do harm to
the eye.
The informaon, such as the range of the peak wavelengths and maximum opcal output power of the light by
the SpO
2
sensor can be especially useful to clinicians.
Always observe the plethysmogram (waveform), which is auto-scaled (normalized). When the measured signal
is inadequate, the waveform will be not smooth or irregular, the SpO
2
reading may be unlikely true or displayed
with “--”, and even a technical alarm will be generated. If in doubt, rely on your clinical judgement, rather than
the monitor readout.
Please do not use the SpO
2
sensor and the monitor when doing the MRI imaging, or burn may be caused by
faradism.
For disposal SpO
2
sensor, If the sterile packaging is damaged, do not use it any more.
Check the SpO
2
sensor and cable before use. Do NOT use the damaged SpO
2
sensor.
Before each use, surface-clean sensor and cable with a so gauze pad by saturang it with a soluon such as 70%
isopropyl Ethanol. If low-level disinfecon is required, use a 1:10 bleach soluon.
When the temperature of SpO
2
sensor is abnormal, do not use it any more.
Please do not allow the cable to be twisted or bent.
Please do not use nail polisher or other cosmec product on the nail.
The ngernail should be of normal length.
The SpO
2
sensor cannot be immersed into water, liquor or cleanser completely, because the sensor has no
capability to resist the harmful ingress liquid.
Do not disinfect any SpO
2
sensor by irradiaon, steaming, or ethylene oxide.
Carefully route cables to reduce the possibility of paent entanglement or strangulaon.
☞ The clinical study for SpO
2
measurement accuracy was done on human subjects according to Standard ISO 80601-
2-61.
☞ A funconal tester or SpO
2
simulator can not be used to assess the accuracy of the oximeter or a SpO
2
sensor.
However, it can be used to check how accurately a parcular oximeter is reproducing the given calibraon curve.
Before tesng the oximeter by a funconal tester, please rstly ask the manufacturer which calibraon curve is
used, if necessary, request the manufacturer for its dedicated calibraon curve and download it into the tester.
10.3 Apply the Sensor
1.Select an appropriate sensor and probe according to the module type and paent category..
2. Apply the sensor to the proper site of the paent.
3. Select an appropriate adapter cable according to the connector type and plug this cable into the SpO
2
connector.
