How are blood Oxygen levels determined via a Pulse Oximeter? - pulse oximeter mri

In principle, the pulse oximeter consists of a light source with two lights of different wavelengths, and a sensor. It cut the patient (usually a finger, but you can use your finger or earlobe) to measure light shine through the fabric and at the other end - to absorb the oxygenated hemoglobin and the "deoxygenated hemoglobin light at different wavelengths, so transfer by measuring the relative amount of light through the two light sources, we can calculate the percentage of hemoglobin, the oxygen is. It's not perfect, but - especially if carbon monoxide is required, the ox, the pulse is as as you were on the way of oxygen, so that shows someone who is 100% carbon monoxide poisoning, oxygen saturation, but in fact, probably in a bad condition.
