Noninvasive hemoglobin-measurement-based pulse oximetry

This paper is presented the investigation of a medical instrument known as a pulse oximetry. The development of such an instrument for the non-invasive hemoglobin saturation is described. The software control is used to realize the measurement to be a practical non-invasive sense. Results obtained from the tested samples in the local hospital have shown that the detected signals from this instrument can be used to process the data interpretation for medical diagnosis purpose.
