Pulse Rate Display

The Pulse Rate display is identified by the
in pulses per minute.

Pulse Quality Indicator

The Pulse Quality Indicator display (identified by the
each detected pulse. The color of the Pulse Quality indicator changes with the pulse strength signal,
as described below.
• Green indicates a good pulse strength signal.
• Amber indicates a marginal pulse strength signal. To improve signal quality, reposition the sensor, try
a different sensor type, reduce patient movement, or improve the site's circulation.
• Red indicates an inadequate pulse strength signal. While the Pulse Quality display is red, SpO
pulse rate values are not updated. After about 10 seconds, the values are replaced with dashes,
indicating that readings are not possible.

Low Battery Indicator

When battery capacity is low, the display will blink once each second. If the batteries are not replaced,
they will reach critically low capacity and the display will blink dashes. The Pulse Quality LED will blink
red or amber, not green. After 10 minutes of critically low battery capacity, the display will go blank.

Sensor Fault or Inadequate Signal Display

If the device determines that a sensor fault or inadequate signal condition exists (a sensor disconnect,
failure, misalignment or incompatibility with the monitor) or if a pulse oximeter sensor signal is no
longer detected, a dash (-) appears in the leftmost position of the SpO
displayed will freeze for 10 seconds if the pulse oximeter sensor fault or the inadequate signal
continues.
If the sensor fault or the inadequate signal is not corrected, the frozen readings and the dash in the
leftmost position will be replaced by dashes in the middle of both the SpO
displays.
When the sensor fault or the inadequate signal is corrected, the SpO
return to normal operation.
