Actual column headings are in the third row of the Column Heading line.
Patient data, from left to right, are the time that the chart was printed, the
current %SpO
value being measured, the current pulse rate in beats per
2
minute (bpm), the current Pulse Amplitude (PA), and the operating status of
the N-550B.
Time Tag represents a real-time clock in: Day, Month, Year, and 24-hour
clock. The clock is maintained by either AC or battery power.
Patient data and the operating status of the N-550B are highlighted in the
patient data display. Parameter values are displayed directly beneath the
heading for each parameter. In this example, the %SpO
rate (PR) is 190 beats per minute. The asterisk (*) next to the 190 indicates
that 190 beats per minute is outside of the alarm limits, indicated at the
far-right end in the top row, for pulse rate. If no data for a parameter is
available, three dashes (- - -) will be displayed in the printout.
The number under 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 and indicates
a change in pulse volume, pulse strength, or circulation.
