11. Data Port Interface Protocol 104 Technical Discussion Technical Discussion Oximetry Overview N 560 Service Manual The N 560 Pulse Oximeter measures functional oxygen saturation by measuring the light absorption of tissue bone and blood during the pulsatile cycle Red and infrared sensor LED s are used as light sources A photodiode acting as a photodetector senses each received wavelength of light namely incident light less the amount absorbed by tissue for both the red and infrared channels It also feeds corresponding electrical signals from the sensor to the N 560 These signals are then processed by the N 560 software engine to produce SpO2 and pulse rate data Bone tissue pigmentation and venous vessels normally absorb a constant amount of light over time The arteriolar bed normally pulsates and absorbs variable amounts of light during the pulsations The ratio of light absorbed is translated into a measurement of functional oxygen saturation SpO2 Because a measurement of SpO2 is dependent upon light from the sensor excessive ambient light can interfere with this measurement Specific information about ambient conditions sensor application and patient conditions is contained throughout this manual Pulse oximetry is based on two principles that oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light 1 e spectrophotometry and that the volume of arterial blood in tissue
