of interference on a pulse oximeter is due only to the amount of interference,
and is generally non-discriminatory as to its source. Interference may or may
not affect the accuracy of measurements, depending upon its severity, nature,
or duration. Factors which may result in interference include but is not limited
to:
• incorrect sensor application:
– sensor placement on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line
– sensor applied too tightly
– incorrect sensor for placement site
• intravascular dyes, such as indocyanine green or methylene
blue
• externally applied coloring agents, such as nail polish, dye, or
pigmented cream
• failure to cover the sensor with opaque material in high ambient light
conditions, e.g., conditions created from one or more of the following
sources:
– surgical lights, especially xenon light sources
– bilirubin lamps
– fluorescent lights
– infrared heating lamps
– direct sunlight
• physical movement, either patient or imposed activity
• venous pulsation
• dysfunctional hemoglobin
• low perfusion
• intermittent pulsatility or arrhythythmia
• electromagnetic interference (EMI)
• ventilator-induced pressure changes
