Note: The two-letter codes and the symbols that occur in the printout are
described in Table 19 on page 104.
A Trend printout will include all data recorded for up to 48 hours of
monitoring since the last Delete Trends was performed. A new trend point is
recorded every 4 seconds. The figure below is an example of a Trend printout.
The first row of the printout includes information about the type of instrument
delivering the information, the software level, type of printout, and alarm
parameters. The second line lists the headings for the columns. These lines are
printed out every 25 lines, or when a change to an alarm limit is made.
Patient data is represented with a date and time stamp for the data. In the
example above, the "- - -" means that a sensor was connected but the signal
quality of the data being received was too low for the monitor to interpret the
data. Patient data that is outside of an alarm limit is marked with an asterisk
(*).
At the end of the printout "Output Complete" will be printed. This indicates
that there was no corruption of data. If the Output Complete statement is not
printed at the end of the printout, the data must be considered invalid.
