Viewing loops
Loops offer important information about the
response of the patient to mechanical ventilation.
The Cockpit displays loops from supported
MEDIBUS.X devices provided the source devices
make the data available to the MEDIBUS.X
protocol.
Pressure-volume loops illustrate changes in
compliance, resistance, and work of breathing. A
mandatory breath plots counterclockwise, while a
spontaneous breath plots clockwise. Inspiration
starts at a point defined by baseline pressure and
the volume level at the beginning of inspiration.
Flow-volume loops also report mechanical and
spontaneous breaths. Inspiration begins at the
origin and moves upward and clockwise. Expiration
plots below the horizontal axis and progresses
counterclockwise to the original starting point.
To view loops
You can view loops from the Ventilator or the
Anesthesia workstation tabs. Which tab is
displayed depends on whether a ventilator or an
anesthesia workstation is connected.
1 Select the Sensor parameters... button on the
main menu bar.
2 Select the Ventilator tab or the Anesthesia
workstation tab.
3 Select the PV Loop tab to view pressure-
volume loops or select the FV Loop tab to view
flow-volume loops.
4 Select the Loops tab to view all loops in one
dialog.
5 Select the Loop draw button at the bottom of
the pages to choose how many loops are drawn
on top of each other before the screen is
cleared.
6 Select the Save reference button at the bottom
of the page if you want to save a loop for future
analysis and comparison.
NOTE
Depending on which devices are connected to the
Cockpit, two Ventilator tabs may be displayed.
The MEDIBUS.X Ventilator tab is the one that
has the message Medibus.X ventilator devices
displayed as a header on the various pages.
