摘要

This paper presents and compares three volume sensors to be used in mechanical ventilators developed in laboratory: volume sensor based on the Pitot tube, volume sensor based on the Venturi tube and infrared(IR) volume sensor. The three sensors were calibrated and tested with a mechanical ventilator in Pressure-controlled Ventilation (PCV) mode. The maximum pressure changed, keeping textitPositive...
