Using the SE-RDA software
Features of the SE-RDA software main window
The figure shows the SE-RDA software main window. The various functions are identified
and described below.
1.
Main graph area – displays the entire pressure log. Displays Pressure (cm H
2
O)
vs Time (hh:mm:ss). In this example the total duration is 1h 04m 18s.
Note: The negative (inhalation) side of the graph has larger magnitude than the positive
(exhalation) side because the inhalation resistance is higher than the exhalation
resistance.
2.
Selection cursors – click and drag the cursors to select a time range for detailed
analysis.
3.
Cursor timestamps – show the exact cursor positions (hh:mm:ss). You can
enter times here to accurately position the cursors.
4.
Detail graph area – displays the data range as selected between the cursors (2)
in the main graph area (1). Displays Pressure (cm H
2
O) vs Time (hh:mm:ss), or
Flow (l/min) vs Time, as selected with the Press/Flow toggle switch (5).
5.
Press/Flow toggle switch – Toggles the detail graph area (4) between
Pressure and Flow. When Flow is selected, the filter parameters (6) are applied to
calculate the Flow from the Pressure.
Note: The toggle switch can be used to refresh the displayed data after settings have
been changed.
