Performing and Reviewing Calculations
Resampling
Resampling of vital signs enables you to override the values in the
Vital SIgns Trends database, which are stored every 12 seconds or averaged over 1
minute, depending on the monitor's configuration. Resampling enables
you to use the most recent continuously monitored values. Resampling
sets the calculation time to the current time, and displays the
corresponding values for the previous second in the calculations task
window. Resampled values are indicated by a preceding asterisk (*) in
Calculations, Graph Trends, and Vital Signs task windows.
If no current values exist, then the most recent value within 30 minutes
will be retrieved. The most recent height, weight, (and head
circumference for neonatal only) are used regardless of how long ago
they were entered.

time and does the calculations using the resampled values. Pressing any
other softkey except
brings up the database values for the displayed calculation time.
Resampled values that are not stored or used in calculations will be
erased.
When data is transferred with the Data Transfer module, values that
have been resampled are transferred to the destination monitor.
Resampled and other manually entered data is annotated with an
asterisk (*) at the destination monitor if both the source and destination
monitors have software at the Release F level or higher (CMS) or
Release A.0 level or higher (V24 and V26).
