3. Adjust settings as desired by selecting and activating
a parameter, followed by adjustments and activation.
Repeat for each parameters you require. The calculated
inflation time is displayed as
Tmaneuver
.
If you attempt to set
Ptop
to greater than 40 cmH2O,
Tpause
greater than 5 seconds, or
End PEEP
to a value
different from the current PEEP/CPAP, you must reconfirm
your intention through the
Yes
button.
4. When necessary you can change the plot type, see Chang-
ing the Plot type in this section.
5. Select
Start/Stop
to begin the maneuver. When the
maneuver is completed, the window remains open with the
curve displayed for approximately 1 minute, waiting for
possible input before closing.
If the
Start/Stop
button is pushed during a running P/V
maneuver, the maneuver will be terminated immediately
and pressure will be reduced to End PEEP, and the con-
trolled ventilation restarts.
5
Cursor 1
and
Cursor 2.
Each cursor simultaneously selects
two points, one for the inflation and one for the deflation limb.
The points are vertically aligned. Using both cursors you can
determine the linear compliance by obtaining a “best visual fit.”
Data about these points is also displayed.
6
Tmaneuver.
Total maneuver time, calculated.
7
Start/Stop.
Begins maneuver (or ends it at any time).
8 Cursor data. The
Cursor
column shows the values for the
points on the inflation limb (
Infl limb
) and deflation limb
(
Defl limb
) of the curve. The
Cursors
column shows the
calculated compliance in ml/cmH2O for a straight line that
connects the cursor points.
9 Curve, for this example, a pressure/volume curve that includes
both inflation and deflation limbs.
10
Vpeep.
Released volume at the start of a ZEEP maneuver.
11 Time/date. Maneuver date and start time.
1. See for a list of setting ranges, standard settings, and resolutions.
