Abstract: The control-monitor, used in combination with a percussive ventilation breathing head and internal reciprocating injector shuttle, includes in a casing a generator, sensory pulse amplitude, frequency and MAP modules and a gas amplitude and pulsatile frequency control knobs. First and second AMP control indicia include a bent conical AMP indicia (a wide span indicating greater amplitude, a narrow span indicating lesser amplitude) and a single waveform with an adjacent double-headed arrow vertical line. First and second F control indicia include a bent conical F indicia (a wide span indicating greater F and a narrow span indicating lesser F) and multiple waveforms with an adjacent double-headed arrow horizontal line.

Abstract: A percussive ventilation breathing head is adapted to be supplied with a flow of pulsatile gas fed to an elongated breathing head body at a proximal end thereof. The breathing head body defines an interior passageway therein. A reciprocating injector shuttle is movably mounted in the breathing head passageway. The shuttle moves distally due to the pulsatile gas, assisted by a diaphragm and a venturi-like jet nozzle which nozzle pulls nebulized aerosol from a depending plenum and a nebulizer attached below the depending plenum. A depending body defines the plenum. The generally cylindrical nebulizer is attached below the depending body. The shuttle is also biased in a proximal direction within the interior passageway and moves proximally due to the bias. The shuttle defines an internal flow passage from a proximal shuttle input port to a distal shuttle output port at the distalmost mouth of the percussive ventilation breathing head body.
