Oximetry is a test used to measure the oxygen saturation of the blood. It is a quick, painless method to measure how well oxygen is being circulated throughout the body. Primarily analyzing the body parts furthest from the heart.
A pulse oximeter is a sensor device typically applied to a fingertip. It then passes two wavelengths of light to a photodetector/photosensor. It then measures changes in absorbance and determining the absorbances determined only by pulsing arterial blood.
The purpose of an oximeter is to determine the ability of one’s heart at pumping oxygen throughout the body. Specifically, those who may have a condition that affects blood oxygen levels, especially in hospital settings.
Oximeters are small and simple machines but have the ability to determine vital information for your health. They are great to use with oxygen concentrators to verify you are reaching optimal oxygen levels within the body. Remember, on average, normal blood oxygen levels range from 80 to 100 millimeters of mercury. Consult a medical professional about your results and how to manage blood oxygen levels.
