10 Frequently Asked Questions
1. Q: What's SpO
A: SpO
means the saturation percentage of oxygen in the blood.

2. Q: What's the normal range of SpO
A: The normal range varies by individual, but usually over 95%, otherwise,
please consult your physician.
3. Q: What's the normal range of PR value for healthy people?
A: Usually, the normal range is 60bpm~100bpm.
4. Q: Why do the display value of SpO
A: The measured SpO
change of patient's physiological conditions.
5. Q: What to do if there is no SpO
A: Do not shake the finger, and keep calm during the measurement. Please
also avoid the oximeter and the cuff on the same limb for blood pressure and
oxygen saturation measurement simultaneously.
6. Q: How to confirm that the SpO
A: Hold breath for a while (50 seconds or more), if the SpO
decreases, it means that the SpO
dition change.
7. Q: When to charge the batteries?
A: The icon of low battery will appear on the screen when the battery voltages
are low. By then, device need to be charged.
8. Q: What factors will affect the SpO
A: a) Intravascular dyes such as indocyanine green or methylene blue;
b) Exposure to excessive illumination, such as surgical lamps, bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct sunlight;
c) Vascular dyes or external used color-up product such as nail enamel
or color skin care;
d) Excessive patient movement;
e) Placement of a sensor on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line;
f) Exposure to the chamber with High pressure oxygen;
g) There is an arterial occlusion proximal to the sensor;
h) Blood vessel contraction caused by peripheral vessel hyperkinesias
or body temperature decreasing;
i) Low perfusion condition (Perfusion Index is small).
