Abstract
A respiratory control system and apparatus for delivering controlled and or assisted respiratory cycles to the patient includes a flow and pressure control valve, exhalation valve, flow transducer, pressure transducer, and a central control unit that servo controls the flow and pressure valve and the exhalation valve based upon the flow and pressure signals from transducers and control panel. The cycles are initiated by detection of inspiratory effort or in accordance to other criteria, maintaining simultaneously the inspired flow and pressure in the airway at or above a predetermined controlled flow and controlled pressure until the delivery of a predetermined controlled volume, and also extending the maintenance of the controlled pressure by a predetermined period of time after the instant in which the volume was completed, and beyond this period until the delivered flow has decreased until a minimum flow threshold level.
