3.5.4 Review Loops Button
Selecting the Review Loops softkey (see FIGURE 3-28) displays the Review Loops screen (see
FIGURE 3-29). The following areas and selections display:
Small Loop Window: These small graphic windows show the baseline and reference loops. The
baseline loop (only one) is always located on the left and has a white border around its graph. The
reference loops (up to four) are located to the right of the baseline loop. The reference loops are
displayed from oldest (left) to newest (right).
The baseline loop information is displayed below the small baseline loop window. The reference loop
information is displayed in
cyan highlight for the reference loop that is selected.
Large Loop Window: This graphic window shows an enlarged view of the selected reference loop
overlapped with the baseline loop.
Loop Type: Use the Loop Type softkey to choose the type of loop to review. The choices are:
Pressure - Volume, Flow - Volume and Pressure - Flow. Default loop type is Pressure - Volume
loop.
Delete Loop: Use the Delete Loop softkey to delete a selected reference loop. When a reference
loop is deleted, the newer reference loops will shift to the left. The Delete Loop softkey will be
disabled (grayed out) if no reference loops have been saved. The baseline loop cannot be deleted. It
can only be replaced by another baseline loop.
