An ANN based SpO2 Measurement for Clinical Management Systems

Pulse oximeters are ubiquitous in modern medicine to noninvasively measure the percentage of oxygenated hemoglobin in a patient's blood. Pulse oximeters are well adapted, simpler and quite easy to measure. In this paper, An ANN based model using LabVIEW is proposed to measure and estimate the SpO2 present in the blood. Infra red (IR) and red LED lights are passed through the fingers and the ratio of transmission characteristics (R value) is calculated through LabVIEW system. Based on the R value the oxygen saturation SPO2 is calculated. This study is done through aNETka, which is an ANN work system designed in LabVIEW. Finally the result is compared with both fuzzy logic and linear regression based methods. The proposed method shows that ANN can be efficiently used in clinical management systems and also proved its consistency and accuracy.
