Software Revision Level
The next data field tells the user the software level, (Version
2.0.0.0) 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 70% and the high
alarm limit is 100%
. Pulse Rate alarm limits are 60 and 160 bpm.
