The Pulse Amplitude Indicator (blip bar). A 10-segment LED that
indicates pulse beat and shows the relative (non-normalized) pulse
amplitude. As the de
tected pulse becomes stronger, more bars light
with each pulse.
The %SpO2 Display. Shows the saturation level of oxygenated
hemoglobin. The display value flashe
s zero during loss-of-pulse
alarms and flashes the SpO
2 value in red when the SpO2 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.).

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.).
