1. The finger should be placed properly (see the attached illustration of this manual , Figure 5), or
else it may cause inaccurate measurement.
2. The SpO
2
sensor and photoelectric receiving tube should be arranged in a way with the
subject
’
s arteriole in a position there between ．
3. The SpO
2
sensor should not be used at a location or limb tied with arterial canal or blood
pressure cuff or receiving intravenous injection.
4. Make sure the optical path is free from any optical obstacles like rubberized fabric.
5. Excessive ambient light may affect the measuring result. It includes fluorescent lamp, dual ruby
light, infrared heater, direct sunlight and etc.
6. Strenuous action of the subject or extreme electrosurgical interference may also affect the
accuracy.
7. Testee can not use enamel or other makeup.

1. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow 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 like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major
factor blamed for serious error of SpO
2
measure.
4. As the SpO
2
value serves as a reference value for judgement of anemic anoxia and toxic anoxia,
some patients with serious anemia may also report good SpO
2
measurement.
