Abstract: An acoustic ventilator using feedback control is designed to generate and exert a desired mixture of pressure oscillations into a supply of gas entering a subject's airways to maintain optimal ventilation and perfusion in the lungs. According to the subject's biological specifications and real-time medical condition, computers and human interface control the vibrations in intensity and frequency along with the pressure and composition of blended gases in order to enhance oxygenation and CO2 clearance. Acoustic ventilation will cause the ventilating gases to diffuse through the subject's lungs without the aid of a separate ventilator, and with or without spontaneous breathing.

Abstract: The respiratory booster machine is configured to generate and transmit particularly designed and timely delivered vibrations to the lungs of a subject to improve ventilation, augment diffusion of gases across alveolar membrane, facilitate pulmonary blood perfusion, prevent focal alveolar collapse, and enhance effective expectoration. The machine has an acoustic signal generator having modulated wave-generating circuitry and an acoustic signal transmitter having an electro-acoustic transducer. Vibrations from the acoustic signal are induced into the subject's air stream, in one embodiment by a specially designed tube system, and then transmitted to a subject's airways via any type of endotracheal tube, respiratory mask, nasal prong, or directly through the chest wall. Acoustic signal receivers connected to a computer receive and analyze the effect of the vibrations on the subject.
