ELEMETRY TRANSMITTER (96281)
ECG
AND SP O

• An arterial occlusion (blocked artery) proximal to the sensor
• Venous pulsations
• Wrapping the sensor too tightly around the patient’s digit or
other extremity
• Placing the sensor on an extremity with a blood pressure cuff,
arterial catheter, or intravascular line
• Inflating a blood pressure cuff on the limb to which the sensor is
attached
External factors that may adversely affect the accuracy of
oximetry readings include:
• High ambient lighting
• High-frequency electrical noise, such as electrosurgical units and
defibrillators
• The presence of intravascular dyes, such as indocyanine green or
methylene blue, or externally applied coloring, such as nail polish
or pigmented creams
• The patient has hypotension, severe vasoconstriction, severe
anemia, or hypothermia
• The patient is in cardiac arrest or is in shock
Taking the actions that follow may improve SpO
2
performance:
• Select an application site with unrestricted blood flow.
• Do not select a site near potential electrical interference (e.g.,
electronic equipment, electrosurgical units, other power cords).
If possible, remove these electrical noise sources from the area.
• If artificial nails or externally applied coloring agents such as nail
polish are present, select another site or remove the polish/
artificial nails.
• If necessary, wipe the sensor site for 20 to 30 seconds with a
70% isopropyl alcohol pad to improve performance.
• Apply the sensor correctly, ensuring that the LEDs and the photo
detector are properly aligned directly opposite each other,
preferably on a site that minimizes the distance between the
emitter and photodetector. Periodically check to ensure that the
sensor remains properly positioned on the patient.
• Do not restrict blood flow when securing a sensor with tape.
Sources of high ambient light such as direct sunlight, surgical
lights (especially those with a xenon light source), bilirubin
lamps, fluorescent lights, and infrared heating lamps can
interfere with an SpO
2
sensor’s performance and result in
inaccurate measurements. When using SpO
2
under such
conditions, this interference can be reduced by covering the
application site with an opaque material and by ensuring that
the sensor is properly applied.
