Description of Displays and Indicators
The
Pulse Amplitude
Indicator (blip bar). A 10 - segment LED that
indicates pulse beat and shows the relative (non-normalized) pulse
amplitude. As the detected pulse becomes stronger, more bars light with
each pulse.
The %SpO
2
Display. Shows the saturation level of oxygenated
hemoglobin. The display value flashes zero during loss - of - pulse alarms
and flashes the SpO
2
value in red when the SpO

is outside the alarm
limits. During pulse search, the N-560 continues to update the display. If
alarm limits have been changed from their power
- on defaults, a decimal
point (.) is displayed after the SpO
2
value (100.).
The
Pulse Rate
Display. Shows the pulse rate in beats per minute. It
flashes zeros during loss - of - pulse alarms and flashes the beats per minute
value in red when the pulse rate is outside of the alarm limit. During pulse
search, the N-560 continues to update the display. Pulse rates outside of
the pulse rate range (20 to 250 bpm) are displayed as the closest value
within the range. If alarm limits have been changed from their power
- on
defaults, a decimal point (.) is displayed after the pulse rate value (112.).
