Abstract

This article presents and compares three volume
sensors to be used in low-cost mechanical ventilators developed in laboratory: volume sensor based on the Pitot tube, volume sensor based on the Venturi tube and infrared volume sensor. Fluid Mechanics techniques were used to implement the sensors, such as Pitot and Venturi tube. To validate the operation of the sensors, tests were performed at the Hospital Universitario ´ of Universidade Federal do Piau´ı. The graphs were previously plotted in MATLAB software to compare the efficiency of the
sensors.
