The Fingertip Pulse Oximeter is a non-invasive device intended for the spot-check of oxygen
saturation of arterial hemoglobin (SpO
2
) and the pulse rate of adult and pediatric patients in home
and hospital environments (including clinical use in internist/surgery, anesthesia, intensive care ect.).
This device is not intended for continuous monitoring.

The pulse oxygen saturation is the percentage of HbO
2
in the total Hb in the blood, so-called the O
2
concentration in the blood. It is an important bio-parameter for the respiration . F or the purpose of
measuring the SpO
2
more easily and accurately, our company developed the Pulse Oximeter. At the
same time, the device can measure the pulse rate simultaneously .
The Pulse Oximeter features in small volume, low power consumption, convenient operation and
being portable. It is only necessary for patient to put one of his fingers into a fingertip photoelectric
sensor for diagnosis, and a display screen will directly show measured value of Hemoglobin
Saturation.

Principle of the Oximeter is as follows: An experience formula of data process is established taking
use of Lambert Beer Law according to Spectrum Absorption Characteristic s of Reductive
Hemoglobin (Hb) and Oxyhemoglobin ( Hb O
2
) in glow & near-infrared zones. Operation principle of
the instrument is: Photoelectric O xyhemoglobin I nspection T echnology is adopted in accordance
with Capacity Pulse Scanning & Recording Technology, so that two beams of different wavelength
of lights can be focused onto human nail tip through per spective clamp finger-type sensor. Then
measured signal can be obtained by a photosensitive element, information acquired through which
will be shown on screen through treatment in electronic circuits and microprocessor.

1. The finger should be place d properly (see the attached illustration of this manual , Figure 5), or
else it may cause inaccurate measure ment .
2. The SpO
2
sensor and photoelectric receiving tube should be arranged in a way with the
subject ’ s arteriole in a position there between ．
3. The SpO
2
sensor 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 lamp, 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.

1. A s 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.
2. 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 .
3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major
factor blamed for serious error of SpO
2
measure .
4. 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.
