How Do You Calculate Sao2

Spectrophotometry is presently the only method capable of directly measuring SaO2. These devices utilize numerous wavelengths of light and directly measure the concentrations of oxyhaemoglobin and the various dyshaemoglobins, including carboxyhaemoglobin and methaemoglobin.

Is SaO2 the same as SpO2?

Conclusion: Oxygen saturation results determined of different ways are often not identical. The difference between SaO2 and SpO2 are often more 3 pp when SpO2 results obtained from fingertip less than 94%.
