Smiths BCI Pluse Oximeter Report on how SpO2 Readings can Differ among Pulse Oximeters
Principle: Pulse oximetry combines the principles of optical plethysmography and spectrophotmetry to determine arterial oxygen saturation values. Optical plethysmography used light absorbance technology to reproduce waveforms produced by pulsating blood. Spectrophotometry uses various wavelengths of light to perform quantitative measurements about light absorption through given substances.
Each pulse oximetry manufacturer uses various wavelength LEDs which will affect the Ratio obtained. The calibration curve is empirically derived from dynamic data that contains many variables. Manufacturers adjust their proprietary calibration curve in order to meet a specification range. Based on this information, it is understandable how an SpO2 reading can vary from one manufacturer to manufacturer and still be accurate.
