To determine blood oxygen (arterial blood oxygen saturation (SpO2)) and pulse rate, many biosensors use the reflectance of red and infrared (and sometimes green) light. Based on photoplethysmography (PPG), an optical technique that measures blood volume variations, dual-wavelength PPG pulse oximeters noninvasively measure/calculate the arterial oxygen saturation (SpO2). An oximeter transmits radiation at a known […]
