China Mslxy67 TFT Display Bluetooth Finger Pulse Oximeter, Find details about China Finger Oximeter, Finger Pulse Oximeter from Mslxy67 TFT Display Bluetooth Finger Pulse Oximeter
Oxygenated blood absorbs light preferentially at 940nm (near infra-red light), whereas deoxygenated blood absorbs light preferentially at 660nm(red light). A pulse oximeter works by passing a beam of red and infra-red light through a pulsating capillary bed and then measures the amount of red and infra-red light emerging from the tissues via a sensor.The relative a bsorption of light by oxyhemoglobin (HbO) and deoxyhemoglobin is then processed according to the Beer-Lambert's law and the oxygen saturation level (SpO2) determined. For Sports or Aviation use.
