Building A Low-cost Biomedical Device To Improve Accuracy In Pneumonia Diagnosis In Under Five Children

Abstract Pneumonia has been the leading cause of death among children under the age of five in subSaharan Africa, killing more children than the number of children dying from HIV/AIDS. The current methods of diagnosing pneumonia are limited by poor sensitivity and accuracy and they are also expensive. In this project, a low-cost biomedical device was designed and developed to improve the accuracy in diagnosing pneumonia hence assisting in correct prescription of drugs to children. Sounds waves were transmitted from a surface exciter which was connected to an Arduino-powered circuit. The sounds…
