Dir: When you enter the limit value settings, „Dir" is already selected. Long
press the button to switch between up (increase the value) and down
(decrease the value).
High: Briefly press the button to select "High". Long press the button to set the
upper limit prompt of pulse or SpO2
want to change the value is correctly set to up or down. Lower limit can not
exceed the upper limit.
Low: Briefly press the button to select "Low". Long press the button to set the
lower limit prompt of pulse or SpO2
want to change the value is correctly set to up or down. Lower limit can not
exceed the upper limit.
Exit: Briefly press the button to select "Exit", then long press the button to exit
and return to the prompt menu.
6.2. Caution
1. The finger should be placed properly (see the attached illustration of this
manual, Figure 4), or else it may cause inaccurate measurement.
2. The SpO2 probe and photoelectric receiving tube should be arranged in a
way with the subject's arteriole in a position there between.
3. The SpO2 probe 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 lamps, 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.
6.3. Clinical restrictions
A. As the measurements are 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 SpO2 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 SpO2 determination by this monitor may be
inaccurate.
