oximeter that is used six hours a week takes approximately eight weeks to fill the
memory.
1. TREND Softkey—A Trend printout includes all data recorded for up to 45 hours
of monitoring since the last Delete Trends was performed. A new trend point is
recorded every second. At the end of the printout "Output Complete" prints
indicating the data is not corrupt. If the Output Complete statement does not
print at the end of the printout, consider the data invalid.
2. ERRLOG Softkey—Used only by Nellcor's Customer Service Engineering, a
qualified service technician, or a clinical engineer. Selecting the ERRLOG softkey
provides a list of all the errors recorded in memory. The first line lists the type of
oximeter producing the printout, software level, type of printout, and the time of
the printout. The second line of the printout consists of column headings. If
nothing prints out, there have been no errors. At the end of the printout "Output
Complete" prints indicating the data is not corrupt. If the Output Complete
statement does not print at the end of the printout, consider the data invalid.
3. INSTAT Softkey—Used by Nellcor's Customer Service Engineering, a qualified
service technician, or a clinical engineer. In the INSTAT printout, line one is for
oximeter type, software revision level, type of printout, and alarm parameter
settings. The second line contains the column headings. A trend point is recorded
for every four seconds of oximeter operation. Up to 45 hours of oximeter
operation data can be recorded. If the final line on the printout shows "Output
Complete, " then the data has been successfully transmitted with no corruption. If
there is no "Output Complete" line printed, the data should be considered
invalid.
4. INFO Softkey—Used by Nellcor's Customer Service Engineering, a qualified
service technician, or a clinical engineer. Pressing the INFO softkey produces a
single line printout of oximeter information. The data presented in the printout
from left to right, is the oximeter type (N-600x), software version level, type of
printout (INFO), CRC (Cyclic Redundancy Check) number, and ratio of current
operating time to total operating time (the ratio itself has no units of measure).
5. DELETE Softkey—Deletes the most recent trend data. The current trend data,
along with the deleted trends, can be retrieved from the oximeter through an
Instat printout. The oldest deleted trend is Trend 01 on the Instat printout. If a
Trend 01 already exists in memory from an earlier Delete, the next deleted trend
will become Trend 02. Each time DELETE is pressed, the number of existing trends
increases by 1. The current trend has the largest trend number.
