1.5 Clinical indications
The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate
through finger.
2. Principle
Figure 1 Operating principle
Principle of the Oximeter is as follows: An experience formula of data process is estab-
lished taking use of Lambert Beer Law according to Spectrum Absorption Characteristics
of Reductive Hemoglobin (Hb) and Oxyhemoglobin (HbO
