Because the FEV1 Measurement alone is not enough: Cooperation Free Resistance Measurement
A gentle measurement method without influence on the respiratory tract: the Oscillatory Resistance measurement answers the central question for the current degree of obstruction immediately and practically without the patients’ cooperation!
When measuring with ROS-BOX, “normal” tidal breathing replaces the strenuous, cooperation-depending, and error-leading breathing manoeuvre. Oscillation volumes in the range of millilitres make fixing of the cheeks unnecessary. Compared to the usual measurement methods, the bronchial system is practically not being stressed.
