I had honestly never heard of these things before. Oximeters. Sounds weird eh? Kinda fun to say though…so…what are they? Well, oximeters are a medical device that indirectly measures the oxygen saturation of a persons blood. You know, when you go to the hospital, they put these little clippie things on your fingers? Well that is a finger pulse oximeter. Some people need these all the time. If you do..head over to portablenebs.com. Theyve got you covered.
