But despite the fact that the setting on the pressure-gated inspiratory valve for Patient #1 was being decreased, the inspiratory pressure and tidal volumes for Patient #2 remained unchanged.

    Document: 17 to 5 cmH2O as the lung compliance fell. But despite the fact that the setting on the pressure-gated inspiratory valve for Patient #1 was being decreased, the inspiratory pressure and tidal volumes for Patient #2 remained unchanged. This experiment illustrates the potential feasibility of maintaining tidal volumes in one patient with changing lung mechanics, while not affecting the ventilation of the other patient treated with the PReVentS circuit. Figure 13 : Impact of Decreasing Lung Compliance in One Patient. Compliance of mock lung for Patient #1 was decreased by sequentially adding rubber bands to the outside of the rubber ventilator bag. As Patient #1 compliance decreased, tidal volume could be maintained for Patient #1 by adjusting the pressure-gated valve for Patient #1 on the Inspiratory limb. During these maneuvers, tidal volumes for Patient #2 were not affected.
