Displays and Indicators

SpO Display

The SpO display is the upper numeric display. (Identified by the %SpO

symbol; see Figure 2 on page 4.) 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; see Figure 2 on page 4.) This 3-digit LED display shows the pulse
rate in pulses per minute.
Pulse Quality Indicator
The pulse quality indicator, a tricolor LED, blinks once for each detected
pulse. (Identified by the
indicator changes color to indicate changes in the pulse waveform signal that
may affect the SpO
The pulse quality indicator may blink one of three colors: green, yellow, or
red. These colors are similar to the colors of a stoplight:
•
Green indicates that the pulse waveform signal is of good quality and the
SpO and pulse rate data are accurate.
2
•
Yellow indicates that the pulse waveform amplitude is marginal or that the
pulse oximeter has detected artifact. Although the SpO
may be acceptable, corrective measures should be considered if the
indicator continues to blink yellow frequently. To improve the signal
quality, try repositioning the sensor, try a different sensor type, eliminate
patient movement, or improve circulation at the site by massaging the area.
•
Red indicates that the pulse waveform amplitude is inadequate. While the
pulse quality indicator is red, SpO
updated). After approximately 20 seconds, the values are replaced with
dashes indicating that SpO

possible.
