Knowing exact values of the health parameters like percentage oxygen saturation in blood and Heart Rate in case of medical emergencies like surgery or other emergent situations like Covid-19 is a must for the proper diagnosis followed by the medication. During WW II (World War II) the percentage oxygen was made known through the very crude method since no oximetry technology was available. After around a period of three plus decades, in 1974 for the first time the concept of non-invasive pulse Oximetry came to an existence and since then many technological developments took place and still are going on to make the system even more user friendly, cheaper and more importantly the designing of a biomedical electronic instrument to meet utmost accuracy so as to authenticate by the medical doctors in emergencies. Here in this paper the developmental journey of the pulse oximeter is reviewed and the advancement in the existing pulse oximeter is proposed with added feature of measuring the body temperature along with the percentage oxygen in blood and the heart rate and also to have all these parameters online available in real time through GSM technology, so that the real time monitoring of the patients at remote places possible.
