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 dependence unit patients
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.
