ABSTRACT:
An apparatus for the determination of the respiratory passageways resistance, including a flow resistance in the breathing or respiratory flow passageway, whose resistance value is periodically varied by a frequency which lies above the breathing frequency, and including as well a pressure and/or, as occasioned, a flow measurement gauge. In conjunction with the flow resistance, the resistance value thereof is varied in an essential sinusoidal manner, and the pressure and/or flow measurement gauge incorporates two measuring passageways, there being detected in the first passageway only the pressure and/or occasioned flow components in the respiratory passageway due to the lower frequencied breathing, and in the second passageway the higher frequencied resistance variations.
