Displays and Indicators

SpO

Display

The SpO

display is the upper numeric display (identified by the %SpO

symbol). This 3-digit light-emitting diode (LED) display shows the current

oxygen saturation percentage.

Pulse Rate Display

The Pulse Rate display is the lower numeric display (identified by the

symbol). This 3-digit LED display shows the pulse rate in pulses per

minute.

Pulse Quality Display

The Pulse Quality display (identified by the symbol) is a tricolor LED

that blinks once for each detected pulse. The Pulse Quality display

changes color to indicate changes in the pulse waveform signal that may

affect the SpO

data. It may blink green, amber or red.

• 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

and 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 batteries are critically low, the digital displays will go blank, and the

Pulse Quality display will blink amber or red, but not green. After 10

minutes at critically low battery capacity, the pulse oximeter will shut off

automatically.

Sensor Fault or Inadequate Signal Display

If the device determines that a sensor fault 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

display. The readings that are displayed will

freeze for 10 seconds if the pulse oximeter sensor fault or the inadequate

signal continues.
