possibility of patient entanglement or strangulation.
■
Use cables only from the instrument manufacturer to provide protection against the
effects of discharge from a cardiac defibrillator and burns.
■
Do not place the Pulse CO-Oximeter or accessories in any position that might cause it to
fall on the patient. Do not lift the Pulse CO-Oximeter by the power cord or any other cable.
■
Interfering Substances: Dyes, or any substance containing dyes, that change usual
blood pigmentation may cause erroneous readings.
■
SpO
2
is empirically calibrated to functional arterial oxygen saturation in healthy adult
volunteers with normal levels of carboxyhemoglobin (COHb) and methemoglobin
(MetHb). A Pulse CO-Oximeter can not measure elevated levels of COHb or MetHb.
Increases in either COHb or MetHb will affect the accuracy of the SpO
2
measurement.
■
For increased COHb: COHb levels above normal tend to increase the level of SpO
2
.
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
2
. When
elevated levels of COHb are suspected, laboratory analysis (CO-Oximetry) of a
blood sample should be performed.
■
For increased MetHb: the SpO
2
may be decreased by levels of MetHb of up
to approximately 10% to 15%. At higher levels of MetHb, the SpO
2
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.
■
Elevated levels of Methemoglobin (MetHb) will lead to inaccurate SpO
2
and
SpCO measurements.
■
Elevated levels of Carboxyhemoglobin (COHb) will lead to inaccurate SpO
2
measurements.
■
Elevated levels of Total Bilirubin may lead to inaccurate SpO
2
, SpMet, SpCO,
SpHb, SpOC and SpHct measurements.
■
Motion artifact may lead to inaccurate SpMet, SpCO, SpHb, SpOC and SpHct measurements.
■
Very low arterial Oxygen Saturation (SpO
2
) levels may cause inaccurate SpCO
and SpMet measurements.
■
Severe anemia may cause erroneous SpO
2
readings.
■
Hemoglobin synthesis disorders may cause erroneous SpHb, SpOC and SpHct readings.
■
Do not use the Pulse CO-Oximeter or sensors during magnetic resonance
imaging (MRI) scanning. Induced current could potentially cause burns. The Pulse
CO-Oximeter may affect the MRI image, and the MRI instrument may affect the
accuracy of the Pulse CO-Oximetry parameters and measurements.
■
If using Pulse CO-Oximetry 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.
■
For home use, ensure that the Pulse CO-Oximeter’s alarm can be heard from
other rooms in the house, especially when noisy appliances such as vacuum
cleaners, dishwashers, clothes dryers, televisions, or radios are operating.
■
Always remove the sensor from the patient and completely disconnect the patient
from the Pulse CO-Oximeter before bathing the patient.
