Pulse Oximetry is a medical method to determine the amount of oxygen saturated blood in the body. More commonly, it gives information about the fraction of hemoglobin, which is loaded with oxygen out of the total amount of hemoglobin.
The devices which do this task are known as oximeters. Oximeters are mainly of two types. Transmissive and reflectance-based. Of these two methods, the ones based on transmission methods are used more widely because they have lesser limitations compared to the reflectance-based oximeters and more advantages also.
Technically the transmissive type oximeters are clamped on any translucent body part such as a fingertip or earlobe. After that, two wavelengths are passed through that part of the skin, and those two wavelengths are absorbed in the photodiode, which is on the other part of the skin.
The photodiode collects the nonabsorbed light, and then by checking the absorbance of the pulsating blood, the amount of hemoglobin is determined.

On the other hand, the reflectance-based oximeters, as the name suggests, work on the reflectance phenomenon. Unlike in the transmissive oximeters, there is a photodiode on the same side of the light source in this type of oximeters.
Because of this, it can be worn on any of the body parts. In that way, it is more convenient. However, it is essential to note here that this type of oximetry is not clinically approved because of its too many side effects.
