7.3.3.1 Waveforms
The device can plot pressure (Paw or Paux), volume, flow,
CO
2
(FCO
2
or PCO
2
) or plethysmographic waves versus time.
Figure 7-7 shows a pressure waveform. In ASV, INTELLiVENT
®
-
ASV and APV a blue band is displayed. The blue band is the
“safe” pressure zone (10 cmH
2
O below the high Pressure alarm
limit). The high Pressure limit is shown as a blue dashed line.

7.3.4 Loops
NOTE:
When Paw/Paux is selected, both values are displayed
together, plotted versus the second parameter.
The device can display a dynamic loop based on two of the fol-
lowing parameters: pressure (Paw and/or Paux), volume, flow,
or CO
2
(FCO
2
or PCO
2
). There are “pre-defined loops” for
paw/V, paw-paux/V, paw/flow and V/CO
2
. Figure 7-8 shows
a paw/volume loop.
1. Press the
Loop Reference button to store the loop curve
with the current date and time. The past and actual values
are shown (Figure 7-8).
