1. A system comprising:
an oscillatory ventilator configured for oscillating at a plurality of specifically tuned frequencies simultaneously a ventilation gas for bi-directional flow of the ventilation gas to and from a pulmonary region of a patient; and
a ventilator control system, in communication with the oscillatory ventilator, to control a waveform input for the oscillatory ventilator, wherein the waveform input comprises the plurality of specifically tuned frequencies each of which frequencies are below the acoustic range.
