Constant-flow inflation and a prolonged end-inspiratory pause were studied, observing the airway pressures in model lungs. The technique demonstrated the changes associated with compliance, resistance and gas redistribution under varying conditions. The studies suggest that when intratracheal pressures indicate a large element of gas redistribution, constant flow inflation and end-inspiratory pause produce pendelluft, and other pressure patterns are preferable for I.P.P.V.
