Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual

iii

■ Patient Safety - If a sensor is damaged in any way, discontinue use immediately.

■ Always remove the sensor from the patient and completely disconnect the patient

from the Radical-7 before bathing the patient.

■ Interfering Substances: Dyes, or any substance containing dyes, that change usual

blood pigmentation may cause erroneous readings.

■ Do not use the Radical-7 or sensors during magnetic resonance imaging (MRI)

scanning. Induced current could potentially cause burns. The Radical-7 may affect

the MRI image, and the MRI instrument may affect the accuracy of the Radical-7

parameters and measurements.

■ The Radical-7 can be used during deﬁ brillation, but the readings may be

inaccurate for up to 20 seconds.

■ If using Radical-7 during full body irradiation, keep the sensor out of the radiation

ﬁ eld. If the sensor is exposed to the radiation, the reading might be inaccurate or

the instrument might read zero for the duration of the active radiation period.

■

Do not place the

Radical-7

where the controls can be changed by the

patient.

■ Do not place the Radical-7 on electrical equipment that may affect the Radical-7,

preventing it from working properly.

■ Do not expose the Radical-7 to excessive moisture such as direct exposure to

rain. Excessive moisture can cause the Radical-7 to perform inaccurately or fail.

■

Do not place containers with liquids on or near the Radical-7. Liquids spilled on the

Pulse CO-Oximeter may cause it to perform inaccurately or fail.

■

Changes or modiﬁ cations not expressly approved by the party responsible for

compliance could void the user's authority to operate the equipment.

■ SpO

is empirically calibrated to functional arterial oxygen saturation in healthy adult

volunteers with normal levels of carboxyhemoglobin (COHb) and methemoglobin

(MetHb). The Radical-7 can not measure elevated levels of COHb or MetHb.

Increases in either COHb or MetHb will affect the accuracy of the SpO

measurement.

■ Innacurate SpO2 readings can be caused by:

■ Elevated levels of COHb and MetHb

■ For increased COHb: COHb levels above normal tend to increase the level of SpO

The level of increase is approximately equal to the amount of COHb that is present.

NOTE: High levels of COHb may occur with a seemingly normal SpO

. When

elevated levels of COHb are suspected, laboratory analysis (CO-Oximetry) of a blood

sample should be performed.

■ For increased MetHb: the SpO

may be decreased by levels of MetHb of up to

approximately 10% to 15%. At higher levels of MetHb, the SpO

may tend to read in

the low to mid 80s. When elevated levels of 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 (such as nail polish).

■ Elevated levels of Bilirubin
