Block Diagram Pulse Oximeter

In order to build finger or earlobe probes which are small and unobtrusive we need miniature light sources and detectors. Overview pulse oximeters noninvasively measure or continuously monitor oxygen saturation in arterial blood to ensure that there is sufficient oxygenation. Two relationships between the ratio r and the oxygen saturation of the patient.
