Cheapest Price Medical Oximeter Fingertip Pulse Oximeter In Stock
Product Description
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 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.
