What
is this Pulse Oximeter?
This Pulse
Oximeter is a compact, light weighted device, designed for
on the go spot checking of vital signs (blood O2 saturation
& pulse rate), in a simple non-invasive procedure.
By simply
clipping the device to the finger, users can receive a SpO2
and pulse reading, within seconds. The Pulse Oximeter answers
a wide range of needs and serves various roles in the medical
and recreational fields.
Features:
- Suitable for both clinic and Home use
- Measurement of oxygen saturation (SpO2), pulse rate (PR)
- High accuracy. High reliability
- Easy to use with one-key operation
- LCD display
- Compact design. Easy to carry with the weight of 36g
- Automatic power-off when no signal received for 8 seconds
- Use 2 x AAA batteries (batteries included), no adaptor needed
- Low power consumption: able to work continuously over 100
hours
- Low voltage alarm display

Measurement
Principle:
Blood
carries oxygen in two forms, the majority is bound to hemoglobin
(oxyhemoglobin) and the rest is dissolved in the aqueous phase
of blood (the plasma). The dissolved fraction is dependent
upon the partial pressure of oxygen. As the partial pressure
increases, the dissolved fraction of oxygen increases. This
is measured by the standard "Blood Gas Analyser".
To determine how much oxygen is carried in blood, the oximeter
express it indirectly by the percentage of saturation. As
each gram of normal hemoglobin can hold maximally 1.34 milliliters
of oxygen, the value of saturation can be used to calculate
the actual partial pressure, though it is not necessary in
clinical use.
The
Oximeter works according to Lambert Beer Law: The FOS2 omits
a near-infrared pulse (a 660nm ray and 940nm near-infrared
ray). The light passes through the skin, "shines"
red blood cells, and is partially absorbed. The part which
isn't absorbed is reflected and picked up by the photoelectric
sensor. The porportion of absorption for the 2 wavelength
are analyzed. The data is calculated according to the hemoglobin
(R Hb) and Oxyhemoglobin (02 Hb) reflectance factor. Reflectance
factor, is an index that shows the exact amount and length
of light that a substance will absorb, when it is being "shined"
by a certain wave length of light.
The
Fingertip Pulse Oximeter is registered on theAustralian Register
of Therapeutic Goods (ARTG) with the code 136606, and certified
by FDA of United States and CE of Europe.
