2.2 Major Applications and Scope
The Fingertip Oximeter can detect SpO
and indicate the pulse intensity by the bar-display. This device is applicable
to home, hospital (including internal medicine, surgery, anesthesia, pediatrics,
emergency room etc.), oxygen bar, the community medical center, alpine area
and it also can be used before or after sports, and the like.
This device is not appropriate to be used for continuous monitoring.

2.4 Principle of Measurement
The measurement of pulse oximeter is that it uses a multi-functional oxyhe-
moglobinometer to transmit some narrow spectrum light bands through blood
samples and to measure attenuation of spectrum with different wavelengths
according wo the characteristic that RHb, O
light of different wavelength, thereby determining O
fractions. O Hb saturation is called "fractional" O

Fractional O Hb saturation = [O

Oppositely, pulse oxygen oximeter measures functional O
Functional O Hb saturation = [O

Present SpO oximeter transmits light of two wavelengths only, red light (wave-
2
length 660 nm) and infrared (wavelength 940 nm), to differentiate HbO
HbR. One side of the sensor contains two LEDs, and the other side contains a
photoelectric detector.
