Pulse Oximeter

Caption

The ability to accurately measure oxygen saturation without the use of a pulse oximeter is something that has never been achieved, until now. The pulse oximeter, a non-invasive medical device usually placed on the patient's finger, measures the proportion of oxygen in the blood, combining status of the two major circulatory systems, the heart and the lung.
