    Snippet: To document proof-of-principle for the PReVentS circuit, and to test its ability to separately control ventilatory pressures for two patients, we assembled the circuit attached to a standard ICU ventilator. Standard test lungs (eg. BioMed Device # 1020 or similar) were used to simulate patient lungs. To simulate a decrease in lung compliance, we applied rubber bands around one of the test lungs to increase their stiffness. Figures 10-14 below sho.....
    Document: To document proof-of-principle for the PReVentS circuit, and to test its ability to separately control ventilatory pressures for two patients, we assembled the circuit attached to a standard ICU ventilator. Standard test lungs (eg. BioMed Device # 1020 or similar) were used to simulate patient lungs. To simulate a decrease in lung compliance, we applied rubber bands around one of the test lungs to increase their stiffness. Figures 10-14 below show data obtained from the PReVentS circuit as described above. With the current hand-made valves it is necessary to briefly open the circuit to make valve adjustments. We are working to update the valve design so that pressures can be set without making any disconnects in the PReVentS circuit.
