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.
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, histogram 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.
Screen Trend information is taken from the Trends database. If you do not see a Screen Trend for a
particular measurement on the Screen, check the trend priority list to ensure that this measurement is
