In this diagram, the tidal loops recorded under load are shown in
relation to each other and in relation to the resting flow / volume
loop. This allows the assessment of dynamic hyper-inflation as
well as flow limitations.
The area of the tidal loops that touches or exceeds the resting-
flow / volume loop and is thus presumably flow-limited is shown
in red.
In the table, the measured values of the individual tidal loops and
the resting-flow/volume loop are shown in order to be able to
evaluate them on the basis of the numerical results.
