SIGNAL IQ

The Radical display provides a visual, indicator of the plethysmogram signal quality and an

alert when the displayed SpO

values are not based on adequate signal quality. The signal

quality indicator displayed on the Radical is called the Signal IQ.The Signal IQ can be used

to identify the occurrence of a patient's pulse and the associated signal quality of the

measurement.

With motion, the plethysmographic waveform is often distorted and may be obscured by

artifact. The Signal IQ, shown as a vertical line, coincides with the peak of an arterial

pulsation. Even with a plethysmographic waveform obscured by artifact, the Radical locates

the arterial pulsation. The pulse tone (when enabled) coincides with the vertical line of the

Signal IQ.

The height of the vertical line of the Signal IQ indicates the quality of the measured signal.

A high vertical bar indicates that the SpO

measurement is based on a good quality signal.

A small vertical bar indicates that the SpO

measurement is based on data with low signal

quality. When the signal quality is very low the accuracy of the SpO

measurement may be

compromised, and a “Low Signal IQ” message is displayed in the message area on the

Radical display. When the "Low Signal IQ" message appears proceed with caution and do

the following:

■

Assess the patient.

■

Check the sensor and ensure proper sensor application. The sensor must be well

secured to the site for the Radical to maintain accurate readings. Also, misalignment

of the sensor's emitter and detector can result in smaller signals.

■

Determine if an extreme change in the patient's physiology and blood flow at the

monitoring site occurred, (e.g. an inflated blood pressure cuff, a squeezing motion,

sampling of an arterial blood specimen from the hand containing the pulse oximetry

sensor, severe hypotension, peripheral vasoconstriction in response to hypothermia,

medications, or a spell of Raynaud's syndrome.)

■

With neonates or infants, check that the peripheral blood flow to the sensor site is

not interrupted. For example, as may occur while lifting or crossing their legs, during

a diaper change.

After performing the above, if the "Low Signal IQ" message is displayed frequently or

continuously obtaining an arterial blood specimen for CO-oximetry analysis may be

considered to verify the oxygen saturation value.
