Software Revision Level
The next data field tells the user the software level, (Version
1.0.0.1) and a software verification number (CRC: XXXX).
Neither of these numbers should change during normal operation.
The numbers may change if the monitor is serviced and receives a
software upgrade.
Alarm Limits
The last data field in the top line indicates the high and the low
alarm limits for %SpO
2 and for the pulse rate (PR). In the
example above, the low alarm limit for SpO
2 is 30% and the high
alarm limit is 100%. Pulse Rate alarm limits are 100 to 180 bpm.

Actual column headings are in the second row of the column
heading line. Patient data that is presented in the chart, from left
to right, is the time that the patient data on the row was obtained,
the current %SpO
2 value being measured, the current Pulse Rate
in beats per minute (BPM), the current Pulse Amplitude (PA),
and the operating status of the NPB-290.
