Mechanical Vent Test 1 Practice

Flow Controller Ventilation actively regulates the inspiratory flow and uses a flow sensor to measure that flow. The tidal volume is then calculated by integrating the measured flow over the inspiratory interval (Vt = ∫ Q dt). Because the system controls the flow waveform and continuously derives volume from it, the flow and derived volume waveforms remain consistent breath to breath. Other approaches rely on ending inspiration by reaching a set volume, limiting pressure, or cycling by time, none of which centers on measuring flow to compute volume in the same controlled way.
