Radical-7 system.
Troubleshooting Measurements
See
Safety Warnings and Cautions
on page 15.
Signal IQ (SIQ)
The Signal IQ provides an indicator of the assessment of the confidence
in the displayed SpO
2
value. The SpO
2
SIQ can be also used to identify
the occurrence of a patient’s pulse.
With motion, the plethysmographic waveform is often distorted and may
be obscured by artifact. Shown as a vertical line, the SpO
2
SIQ coincides
with the peak of an arterial pulsation. Even with a plethysmographic
waveform obscured by artifact, the Signal IQ identifies the timing that the
algorithms have determined for the arterial pulsation. The pulse tone
(when enabled) coincides with the vertical line of the SpO
2
SIQ.
The height of the vertical line of the SpO
2
SIQ provides an assessment of
the confidence in the measurement displayed. A high vertical bar
indicates higher confidence in the measurement. A small vertical bar
indicates lower confidence in the displayed measurement. When the
Signal IQ is very low, this suggests that the accuracy of the displayed
measurement may be compromised. See

When parameters are dimly lit, proceed with caution and do the
following:
• Assess the patient.
