medical alcohol by soft material. Do not spray any liquid on the device directly.

When cleaning the device with water, the temperature should be lower than 60°C.

As to the fingers which are too thin or too cold, it would probably affect the normal measure of the
patients' SpO2 and pulse rate, please clip the thick finger such as thumb and middle finger deeply
enough into the probe.

The pulse oximeter can be used to adult or infant. Whether the device is used to adult or infant, it
depends on the probe selected.

The update period of data is less than 30 seconds, which is changeable according to different
individual pulse rate.

The waveform is normalized. Please read the measured value when the waveform on screen is
equably and steady-going. Here this measured value is optimal value, and the waveform at the
moment is the standard one.

If some abnormal conditions appear on the screen during test process, pull out the finger and
reinsert to restore normal use.

The device has normal useful life for three years since the first electrified use.

check the chapter 6.1 as a reference.

The device may not work for all patients. If you are unable to achieve stable readings, discontinue
use.
2. Overview
The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2
concentration in the blood. It is an important bio-parameter for the respiration. A number of diseases
relating to respiratory system may cause the decrease of SpO2 in the blood, furthermore, some other
causes such as the malfunction of human body's self-adjustment, damages during surgery, and the
injuries caused by some medical checkup would also lead to the difficulty of oxygen supply in human
body, and the corresponding symptoms would appear as a consequence, such as vertigo, impotence,
vomit etc. Serious symptoms might bring danger to human's life. Therefore, prompt information of
patients' SpO2 is of great help for the doctor to discover the potential danger, and is of great
importance in the clinical medical field.
