Measuring of oxygen saturation using pulse oximeter based on fuzzy logic


The pulse oximeter is the most used device due to be a noninvasive method in measuring the oxygen level in blood. In the pulse oximeter, red and IR (Infrared) LEDs (light emitting diode) sent signals to the photodiode. An equation or relationship between the ratio (R) of signals (red and IR) received by photodiode with the oxygen saturation value (SpO<sub>2… (More)
