Markers
During an investigation, markers can be placed to indicate interesting events
or to invoke calculation of parameters. Markers are displayed as colored
vertical lines on the screen.
There are two types of markers:
•
Immediate markers
are placed at the plot line. This is the line at which the
curves start.
•
Delayed markers
are placed at the marker line. This allows some time to
consider where the marker should be placed. The marker line is the vertical
line in the plot window at a certain distance from the plot line. In the
investigation protocol, the marker line distance (time for the curves to reach
the marker line) can be set.
Some markers are used for all investigations and other markers are specific to
one investigation.
Artefact marker
(delayed marker)
Coughing or movement by the patient can cause an undesired change in the
pressures. For that, you can place an
artefact
marker before and after the
artefact. The data between the two artefact markers will be excluded from the
calculations. Artifact markers can be placed with the
Artefact
button on the
screen or with the
Artefact
key on the remote control.
In the investigation protocol, you can specify
automatic artefact detection
.
The software will then automatically place artefact markers around an artefact.
When artefact is active, the
Artefact
button will be down, and the curves show
red borders.
Event marker
An event marker marks a point of interest during an investigation and has no
influence on parameter calculations. Event markers can be placed with the
Event
button on the screen or with the
Event
key on the remote control. By
default, event markers are delayed markers. Choose
