Attention for operation
A.
Please check the device before using, and
confirm that it can work normally.
B
.
The finger should be in a proper position (see the
attached illustration of figure 4 for reference), or else
it may result in inaccurate measure.
C
.
The SpO
2
sensor and photoelectric receiving
tube should be arranged in a way with the subject
’
s
arteriole in a position there between.
D
.
The SpO
2
sensor should not be used at a location
15
or limb tied with arterial canal or blood pressure
cuff or receiving intravenous injection.
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
