Abstract
Oscillatory ventilator configured for oscillating at a plurality of specifically tuned sinusoidal frequencies simultaneously a ventilation gas for delivery to a lung region of a patient and a ventilator control system, in communication with the oscillatory ventilator, to control a sinusoidal waveform input for the oscillatory ventilator, wherein the sinusoidal waveform input comprises the plurality of specifically tuned sinusoidal frequencies each of which sinusoidal frequencies are below the acoustic range.
Claims20
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.
A method comprising:
- producing a waveform input comprising a plurality of specifically tuned frequencies each of which frequencies are below the acoustic range;
- and
- oscillating with an oscillatory ventilator gas for bidirectional flow to and from a pulmonary region of a patient based on the waveform input.
A method of treating a patient, the method comprising:
