| Abstract: | Over the last two decades, the advances in ventilatormodalities and technology have revolutionized the mechanicalventilation process. The new anesthesia ventilatorsconstitute adaptations of machines previously used in intensivecare units.

However, the FLOW-i behavior has notbeen so far tested in a leaking circuit.In this study we tested FLOW-i, and compared to SERVO-i,in volume-, pressure-, and pressure-regulated volumecontrolledmodes (VC, PC, and PRVC, respectively) withgas flows of 6, 1, and 0.3 L/min, booth in airtight and leakingcircuit.In the airtight system both ventilators behaved similarly.FLOW-i delivered preset tidal volume and maintained ventilationand circuit pressure at the same levels independently ofventilatory mode or fresh gas flow rate.
