Pulse oximetry is a non-invasive strategy, that allows identifying the percentage of oxygen saturation of hemoglobin in the patient’s blood by using photoelectric methods.
To do this technique, the pulse oximeter is placed on an element of the body that is relatively transparent and has a good blood circulation, for instance the hands, foot or earlobe. The pulse oximeter produces lights with wavelengths, red and infrared, which move sequentially from an emitter into a photodetector through the person. The absorbance for each wavelength due to arterial blood (pulsatile component) is assessed, not including venous blood, skin, bone, muscle tissue, fat. With one of these devices it will be possible to estimate the blood oxygen saturation.
