Title: Pressure-Regulated Ventilator Splitting (PReVentS): A COVID-19 Response Paradigm from Yale University Document date: 2020_4_6

Snippet: For this experiment, the circuit was connected to two mock lungs having similar compliance. The goal of the experiment was to tune the pressure settings in the pressure-gated valves in the inspiratory circuit, and to measure the resultant airway pressures for the two simulated "patients" (Figure 10). As described above, the inspiratory pressure for each patient is set by subtracting the setting of that patient's inspiratory pressure-gated valve f.....
Document: For this experiment, the circuit was connected to two mock lungs having similar compliance. The goal of the experiment was to tune the pressure settings in the pressure-gated valves in the inspiratory circuit, and to measure the resultant airway pressures for the two simulated "patients" (Figure 10). As described above, the inspiratory pressure for each patient is set by subtracting the setting of that patient's inspiratory pressure-gated valve from the ventilator's peak inspiratory pressure. Hence, for a set ventilator PIP of 35, a pressure-gated valve setting of 15 for Lung B results in an inspiratory pressure of 20 for that lung. Of note, the airway pressures of Lung A were entirely unchanged when varying the PIP of Lung B.
