| Abstract: | Objective To study non-invasive measurement of reflectance oxygen saturation. Methods Diffusion theory was used to explain the action of light in tissue and deduce reflectance oxygen saturation formula. Then, Reflectance Oxygen Saturation Detection System based on MSP430 was developed and calibrated. Result The calibration result and calibration curve was ascertained and analyzed. Conclusion The formula for detection and measurement of oxygen saturation is put forward by using Reflectance Oxygen Saturation Detection System. |
| Keywords: | oxygen saturation transmittance reflectance calibration |
