The present invention relates generally to devices and methods for finite control and regulation of patient intrathoracic pressures, and more specifically, to devices and methods that are finitely adjustable within a range set by an operator for regulating a patient intrathoracic pressures during repeated cycling events (i.e. respiration). The enhanced means includes a dual area valve on an exhalation and/or inhalation port of a device such that the valve is biased against the pressure necessary to evacuate and/or inflate the lungs of that patient by at least a partial volume thereof. The enhanced means for regulating intrathoracic pressure are applicable in a number of medically important therapies, including but not limited to, conditioning of pulmonary systems for acclimation to altered environmental conditions, reconditioning of pulmonary system after operating in a diminished state, and application in cardiopulmonary resuscitation procedures.
