E. Do not fix the SpO
2
sensor with adhesive or else it may result in venous pulsation and inaccurate
measure of SpO
2
and pulse rate.
F. Excessive ambient light may affect the measuring result. It includes fluorescent lamp, dual ruby
light, infrared heater, direct sunlight and etc.
G.Strenuous action of the subject or extreme electrosurgical interference may also affect the
accuracy.
H. Testee can not use enamel or other makeup.
I. Please clean and disinfect the device after operating according to the User Manual (7.1).
6.3 Clinical Restrictions
A. 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.
B. 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.
C. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor
blamed for serious error of SpO
2
measure.
D. 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.
7 Maintain, Transportation and Storage
7.1 Cleaning and Disinfecting
Using medical alcohol to disinfect the device, nature dry or clean it with clean soft cloth.
7.2 Maintain
A. Please clean and disinfect the device before using according to the User Manual (7.1).
