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.
