Design and performance of 3DP Flow Restrictor (FloRest). A Vent-Lock 3DP Flow Restrictor (FloRest) contains three components. The O-ring between the cap and full-height threaded needle interface at the top of the chamber to maintain air-tight seals. Both ends of Vent-Lock FloRest are male ISO fittings to ensure connection to ventilator tubing. B Testing with a ventilator on pressure control using simulation lungs at varying compliances demonstrates that Vent-Lock FloRest provides more control options than commercial ball valves and gate valves, characterized by more available data points corresponding with different tidal volumes delivered
