Remote optical monitor of blood oxygenation
Pulse oximetry is a widely used technique in biomedical analyses. It enables monitoring the percentage of saturated hemoglobin and heart pulse in a noninvasive way. The mandatory permanence of patients in medical facilities due to continuous measurements of blood oxygen saturation and cardiac pulse can be avoided by taking advantage of nowadays telecommunications technologies. This paper describes a pulse oximeter capable of operating in standalone mode and wirelessly transmit the data to a display unit.
