Abstract:
1. An intrathoracic pressure regulator system for use in treating a patient, the system comprising: a patient port adapted to fluidly communicate with the patient; a ventilator port that fluidly communicates with a ventilator mechanism for facilitating a positive pressure ventilation procedure administered to the patient via an inspiratory chamber and the patient port; a vacuum port that fluidly communicates with a vacuum mechanism for facilitating a vacuum procedure administered to the patient via an expiratory chamber and the patient port; and a valve for controlling gas flow, wherein during administration of the positive pressure ventilation procedure the valve allows gas flow between the ventilator port and the patient port and inhibits gas flow between the vacuum port and the patient port, and during administration of the vacuum procedure the valve inhibits gas flow between the ventilator port and the patient port and allows gas flow between the vacuum port and the patient port by allowing expired gas to pass from the patient port through an expiratory chamber to the vacuum port, and wherein the valve is configured to regulate, throughout consecutive breathing cycles, expiratory pressure in the patient port between 0 and −20 cm H wherein the patient port comprises an inspiratory lumen that is at least partially contained within an expiratory lumen, wherein the inspiratory lumen is sealed from the expiratory lumen, and wherein an inspiratory path traverses the expiratory chamber and communicatively couples with the inspiratory lumen.
