CAUTION
 Do not use tape to secure the sensor to the site; this can restrict blood flow and
cause inaccurate readings. Use of additional tape can cause skin damage or
damage the sensor.
 The sensor should be free of visible defects. Never use a damaged sensor or
one with exposed electrical circuitry.
 To prevent damage, do not soak or immerse sensor in any liquid solution. Do
not attempt to sterilize the sensor.
 Carefully route cable and patient cable to reduce the possibility of patient
entanglement or strangulation.
 Intravascular dyes or externally applied coloring (such as nail polish) may lead
to inaccurate SpO
2
measurements.
 Elevated levels of Carboxyhemoglobin (COHb) may lead to inaccurate SpO
2
measurements.
 Elevated levels of Methehemoglobin (MetHb) may lead to inaccurate SpO
2
measurements.
 Failure to apply the sensor properly may cause incorrect measurements.
 Do not use the sensor during MRI scanning.
 If using pulse oximetry during full body irradiation, keep the sensor out of the
irradiation field. If sensor is exposed to the irradiation, the reading might be
inaccurate or the unit might read zero for the duration of the active irradiation
period.
 Avoid placing the sensor on any extremity with an arterial catheter or blood
pressure cuff.
 The pulsations from intra-aortic balloon support can be additive to the pulse
rate on the oximeter pulse rate display. Verify patient’s pulse rate against the
ECG heart rate.
 Do not modify or alter the sensor in any way. Alterations or modification may
affect performance and/or accuracy.
 Venous congestion may cause under reading of actual arterial oxygen
saturation. Therefore, assure proper venous outflow from monitored site.
Sensor should not be below heart level (e.g. sensor on hand of a patient in a
bed with arm dangling to the floor).
 Venous pulsations may cause erroneous low SpO
2
readings (e.g. tricuspid
value regurgitation).
