Trends Databases
Depending on the purchased options and the monitor’s configuration, the trends databases store
information for up to 32 measurements for up to 72 hours.
The values in the trends database are stored as measured by the monitor, they are not averaged values.
The trend resolution defines how often a value is stored. In general, if more than one value is available
for storage in the trends database, the most recent value is used. Some values in the trends are marked
with arrows. This indicates that for this time period, more values were available and the most recent
one is shown.
Example database configuration In this example, we see that the monitor stores the most recent data
at the highest resolution, older data are stored at a lower resolution.
“4 hours @ 12 second resolution” means that the monitor stores trend data every 12 seconds, for the
most recent four hours.
Aperiodic Trends Database
Aperiodic trends do not count toward the maximum number of trends allowed by the trend
configuration. Trend data for aperiodic measurements is stored in a separate database and timestamped
with the measurement time.
Trending Multiple-Value Measurements
Some measurements generate multiple values, for example invasive pressure measurements can provide
systolic, diastolic, and mean values. These values are trended as separate measurements.
Screen Trends
Trends configured to display permanently on special monitor Screens are called screen trends. The
selection and number of measurement waves in the Screen Trend segment depends on your monitor
configuration. Screen trends are color-coded to match the measurement wave and numerics, and they
can be viewed in graphical, tabular, or horizon format.
If you do not see screen trends on the monitor Screen, select a different Screen, one that is configured
to show screen trends. Screen trends are only available on specially designed Screens.
