Design and Implementation of a Low-Cost Wearable Blood Oxygen Saturation and Pulse Measurement Device.

The main aims of the current work are to design, fabricate, and test a low-cost, easy-to-operate portable pulse oximeter device capable of providing immediate blood oxygen saturation and heart rate readings with high accuracy for various disease conditions and all age groups. It can be used in intensive care departments, operating rooms, and health centers as well as at homes. The obtained results were compared using a calibrated device produced by a reputable company. The clinical examination results were evaluated by using the Export System 13.0 statistical software program. The readings are close to each other, with an error rate of less than 1%. The obtained results show that, in the case of a respiratory disease such as chronic obstructive pulmonary or other lung diseases, the percentage of oxygen saturation decreased to between 73 to 88 %. For patients with heart disease, it was found that the oxygen saturation level changes significantly according to the type of disease. These obtained values decreased by 11.11 %, and 7.08% compared to healthy people, respectively. For the smokers, the blood oxygen saturation rate decreased by 10.47% and 8.06% compared to healthy people, respectively. For those infected with the COVID-19 epidemic, the rate of blood oxygen saturation and heart rates decreased sharply by 31.51 % and 27.03 %, and by 14.67% and 16.67 % compared to healthy people for males and females, respectively. For asthma patients, the rate of blood oxygen saturation and heart rate decreased by 2.50 %, and 4.65 %, and increased by 4.65 % and 4.76 % compared to healthy people for male and female, respectively. For physical activities, such as athletes, the rate of blood oxygen saturation and heart rate were increased by 1.05 %, 3.19 %, 23.26 %, and 28.57 % compared to healthy people for males and females, respectively.
