Development and Evaluation of Wireless Oxygen Saturation Monitoring System

Oxygen saturation (SpO2) is a critical parameter used to measure the amount of oxygen bound to hemoglobin in the bloodstream. Continuous monitoring and accurate records on the patient’s SPO2 are crucial to assist doctors in assessing the effectiveness of treatment and the need for supplemental oxygen. Therefore, this project proposes the development of a pulse oximeter device using dual RFID communication to enable continuous, real-time, and wireless data recording. The reading of SPO2 can vary in various situations. The evaluation to investigate significant factors that could affect the accuracy of SpO2 readings is carried out using the Design of Experiment and Analysis of Variance. The statistical analysis showed that the types of fingers and nail substances are the main factors that influence the accuracy of SpO2. The main effect plot shows that the SPO2 reading on the nail with oil substance and thumb gives the highest accuracy compared to other types of substance and types of fingers, respectively.
