Peripheral Pulse Oximeters Market Analysis | Europe | 2016-2022 | MedCore

Pulse oximetry devices are used for measuring the oxygen content bound to hemoglobin within a patient’s blood stream. The measurement is taken non-invasively by attaching the device to an adult patient’s finger or earlobe, whereas in neonatal patients, the device can be attached to the foot due to the patient’s smaller size. A light containing both red and infrared wavelengths is passed through this part of the body. A measure of oxygenation can be made based on the ratio of changing absorbance of the red and infrared light caused by the difference in color between oxygen-bound and oxygen unbound blood hemoglobin.
