Warning: Do not place containers with liquids on or near Radical-7.
Liquids spilled on Radical-7 may cause it to perform inaccurately or fail.
Warning: Radical-7 is intended only as an adjunct device in patient
assessment. It should not be used as the sole basis for diagnosis or
therapy decisions. It must be used in conjunction with clinical signs and
symptoms.
Warning: A functional tester cannot be used to assess the accuracy of
the Radical-7.
Warning: Interfering Substances: Dyes, or any substance containing dyes,
that change usual blood pigmentation may cause erroneous readings.
Warning: SpO2, SpCO, SpMet, and SpHb are empirically calibrated in
healthy adult volunteers with normal levels of carboxyhemoglobin (COHb)
and methemoglobin (MetHb).
Warning: Inaccurate SpO2 readings may be caused by:
Improper sensor application.
Elevated levels of COHb or MetHb: High levels of COHb or
MetHb may occur with a seemingly normal SpO2. When elevated
levels of COHb or MetHb are suspected, laboratory analysis (CO-
Oximetry) of a blood sample should be performed.
Intravascular dyes, such as indocyanine green or methylene blue.
Externally applied coloring and texture, such as nail polish, acrylic
nails, glitter, etc.
Elevated levels of bilirubin
