Respiratory flow estimation using data fusion techniques

Abstract

Due to the evolution of electronics and measurement processes, today there are many systems and methods that can be used for measuring airflow, such as the method of differential pressure across of a pneumotachograph or measurements using various anemometers. This research proposes the design and development of a system for measuring respiratory flow using data fusion of information from the Transit Times method (ToF) obtained by the techniques of detection threshold and phase difference.
