Real patient example showing high resolution volume-over-time graph with corresponding unfiltered cycle-by-cycle data graph. The graph above represents high resolution volume over time graph; the graphs under illustrate unfiltered cycle-by-cycle graphs of VT where one point represents one respiratory cycle. On the left, unfiltered cycle-by-cycle is represented without connected dots and on the right with connected dots (i.e two possible representations of cycle-by-cycle data). The red squares on the unfiltered cycle-by-cycle graphs correspond to the high-resolution data represented above.
