1. A system for providing intrathoracic pressure regulation (IPR) to an individual, the system comprising:

  • a patient connection mechanism for coupling with an airway of the individual;

    a flow control assembly comprising a housing having a vent, an impeller disposed within the housing, and a motor in operative association with the impeller; and

    an external pressure source selected from the group consisting of a manual bag valve mask mechanism, a mechanical ventilator machine, and an anesthesia machine,wherein the external pressure source is in fluid communication with the housing vent of the flow control assembly,wherein the impeller of the flow control assembly is disposed between the patient connection mechanism and the external pressure source, along a fluid passage that extends between the patient connection mechanism and the external pressure source, andwherein the flow control assembly is configured to allow retrograde airflow from the external pressure source to the patient connection mechanism while simultaneously compelling airflow from the patient connection mechanism to the housing vent.
