APPARATUS FOR THE DETERMINATION OF THE RESPIRATORY PASSAGEWAY RESISTANCE

摘要

An apparatus for the determination of the respiratory passageway resistance. Apparatus of that type in general evidence a flow resistance located is the respiratory passageway, whose resistance value is periodically varied at a frequency which is located above the breathing frequency, or a breathing tube with a flow resistance and a pulse generator or subjecting the breath flow with higher-frequencied pressure- or, respectively flow pulsations.
