Time Tag does not represent a real-time clock. The number beneath the Time
Tag heading represents time, in seconds, since the unit was initialized at the
factory. This number will increase in size throughout the life of the monitor.
Patient Data
NPB-190 Version 1.0.0 CRC XXXX SpO2 Limit: 30-100% PR Limit: 100-180 bpm
Time Tag %SpO2 PR (bpm) PA Status
123456795 100 190* 220 PH
Patient data are highlighted in the display above. Parameter values are displayed
directly beneath the heading for each parameter. In this example, the %SpO
2 is
100, and the pulse rate PR is 190 beats per minute. The “*” next to the 190
indicates that 190 beats per minute is outside of the alarm limits, indicated in the
top row, for pulse rate. If no data for a parameter is available three dashes (- - -)
will be displayed in the printout.
PA is an indication of pulse amplitude. The number can range from 0 to 254 and
will typically range around 45. There are no alarm parameters for this value. It
can be used for trending information. It is an indication of a change in pulse
volume, pulse strength, or circulation.
