A high frequency ventilator which generates a high frequency pressure wave in a supply of ventilating gas for supporting ventilation in air breathing animals. The high frequency pressure wave causes the ventilating gas to be exchanged and to diffuse through the animal\s lungs fast enough to support ventilation without spontaneous breathing on the part of the animal and without the aid of a separate ventilator.

An apparatus for supporting full ventilation in an air breathing animal comprising: means for supplying a respirating gas to an animal at elevated pressure, a linear motor, a diaphragm driven by said linear motor, and circuit means for producing a high frequency, variable frequency, variable amplitu

An apparatus for supporting full ventilation in an air breathing animal comprising: means for supplying a respirating gas to an animal at elevated pressure, a linear motor, a diaphragm driven by said linear motor, and circuit means for producing a high frequency, variable frequency, variable amplitude signal for driving said linear motor to drive said diaphragm to generate a pressure wave in said gas which is polar relative to the static pressure in an airway of said animal, said pressure wave having a positively sloped portion forcing gas into said airway and a negatively sloped portion drawing gas out of said airway.
