Abstract

An opposing vortex oscillator is used to control the frequency and duty cycle of a high-frequency jet ventilator for trauma management in acute and uncontrolled situations where no power other than the pressure of the ventilation gas itself is available. Frequency adjustment is achieved by connecting variable volumes to one inlet of the oscillator while duty cycle control is achieved by supplying fluid to one inlet of the oscillator through a variable-orifice bias control valve. Safety means are provided to automatically disable the ventilator in case of airway blockage.
