Tips to Prevent Artifacts
WARNING !
Only use Nellcor sensors in the recommended
positions, otherwise incorrect measurements
and injury may result.
WARNING !
Damaged sensors with exposed electrical
contacts must not be used – danger of electric
shock.
WARNING !
The adhesive strips must not be stretched
unduly.
Never use two strips together, as this may lead
to venous pulsation and pulse signal failure.
WARNING !
High intrathoracic pressure, pressure on the
thorax, and other consecutive impairments of
the venous flow can lead to venous pulsation
and pulse signal failure.
CAUTION !
The pulse signal may fail in the presence of shock,
low blood pressure, severe vasoconstriction, major
anemia, hypothermia, arterial occlusion proximal to
the sensor, and asystolia.
CAUTION !
The sensor must be protected from exposure to
bright light (e.g., surgical lamps and direct sunlight),
otherwise the pulse signal may fail or the results
may be inaccurate.
CAUTION !
Intravascular dyes, such as methylene blue, may
impair measurement accuracy.
CAUTION !
The sensor should not be positioned on limbs
together with an arterial catheter,
sphygmomanometer cuff, or intravascular venous
infusion, otherwise the pulse signal may fail and
measurements may be inaccurate.
CAUTION !
Measurement accuracy may be reduced in the
presence of significant concentrations of
dyshemoglobins, such as carboxyhemoglobin or
methemoglobin.
CAUTION !
Electrocautery can impair measuring accuracy; the
leads and sensor should therefore be positioned as
far away from the electrocautery and its neutral
electrode as possible.
CAUTION !
Sensor performance may be impaired and lead to
inaccurate results if the patient moves violently. The
sensor should be applied to a quiet/stable site in
such cases, in order to reduce the risk of artifacts
due to movement.
CAUTION !
The displayed plethysmogram is a relative indicator
of the pulse amplitude. Its scale is not absolute and
it is only used to judge the quality of the SpO2
measurement.
CAUTION !
The sensor must not be immersed in liquid – this
may lead to malfunctions.
