ABSTRACT:
A device for manipulating intrathoracic pressures comprises a compressible bag structure, and an interface member coupled to the bag structure. A one way forward valve is coupled to the bag structure to permit respiratory gas to flow to the patient when the bag structure is compressed. A one way exit valve is employed to allow respiratory gases to be pulled from the person's airway upon decompression of the bag structure to produce a negative intrathoracic pressure.
