Still there are some errors to be aware of during the scans. It has a tendency to be accuracy 90% of the time. Furthermore, if there are possibilities to get some errors from scanning the part of the body with less skin density such as fingers, scanning on the wrist will have far more errors than this. Yet, from comparing the two measurements we can find the difference between the error and add them on the taken analysis to get the actual result. Now it is as simple as adding the error of the analysis gap we get both the wrist and the fingertip. After comparing with the market best oximeter with the reading of different individuals the accuracy has been checked and corrected. This system can be efficient for monitoring the COVID-19 patients as they mostly face the falling oxygen saturation sta55 pagesenBrac University theses are protected by copyright.
