2. Make sure that capillary arterial vessel beneath the finger is penetrated through by red and infrared lights.
3. The SpO
2
sensor should not be used at a location or limb tied with arterial or blood pressure cuff or
receiving intravenous injection.
4. Do not fix the SpO
2
sensor with adhesive tape, or else it may result in venous pulsation and consequential
inaccurate measurement result of SpO
2
.
5. Make sure the optical path is free from any optical obstacles like adhesive tape.
6. Excessive ambient light may affect the measuring result. It includes fluorescent lamp, dual ruby light,
infrared heater, and direct sunlight etc.
7. Strenuous action of the subject or extreme electrosurgical interference may also affect the accuracy.
8. Please do not use the SpO2 sensor when having the MRI, or burn may be caused by faradism.
7.4.3 Clinical Limitations
1. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood stream of subject is
required. For a subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or
use of vascular contracting drug, the SpO
2
waveform (PLETH) will decrease. In this case, the
measurement will be more sensitive to interference.
2. For those with a substantial amount of staining dilution drug (such as methylene blue, indigo green and
acid indigo blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic
hemoglobin, and some with icterus problem, the SpO
2
determination by this monitor may be inaccurate.
3. The drugs such as dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor
blamed for serious error of SpO
2
measurements.
4. As the SpO
2
value serves as a reference value for judgement of anemic anoxia and toxic anoxia, the
measurement result of some patients with serious anemia may also present as good SpO
2
value.
7.5 TEMP Monitor
TEMP Measuring Setting：
1. Connect the transducers to TEMP1” or “TEMP2” on the right panel.
2. Attach the transducers to the patient firmly;
Connect the power supply and switch on the monitor.
Note: When unplugging the probe, be sure to hold the head of the connector and pull it out.
