17Trends
Trends are patient data collected over time and displayed in graphic or tabular form to give you a
picture of how your patient's condition is developing. Trend information is stored in the trends
database for continuously-monitored measurements, such as ECG, as well as for aperiodically-
measured parameters, such as Cardiac Output.
Viewing Trends
Trend information can be viewed embedded as a screen element on specially-designed Screens, or you
can open a trend window over the current Screen.
• To view trends embedded as a screen element, enter the
Change Screen window, then select a
Screen designed to show an embedded trend window.
• To open the tabular trends window over the current Screen, select
Main Setup, Trends, then Vitals
Trend
, or select the Vitals Trend SmartKey .
• To open the graphic trends window over the current Screen, select the
Graph Trend SmartKey
.
The trend windows open displaying the most recent data and are updated as new data is stored. A
timescale along the bottom or the top of the screen shows you where you are in the trends database.
The preview column on the right-hand side shows the latest available measurement value. The preview
column is updated every five minutes or whenever an NBP or other aperiodic measurement is
completed.
A question mark (?) beside a value means that the data may not be reliable, due perhaps to an INOP
condition in the measurement.
Your monitor screen may look slightly different to the examples shown in this chapter.
Trends Pop-Up Keys
When you open the graphic, tabular or histogram trends window, a selection of pop-up keys appears to
let you navigate through the stored trend data and carry out trends-related tasks.
