WARNINGS
Many factors may cause inaccurate readings and alarms, decreased
perfusion, and/or low signal strength:
Interfering substances:
- Carboxyhemoglobin may erroneously increase SpO
perfusion, and/or low signal strength:

- Carboxyhemoglobin may erroneously increase SpO
2
readings.
- Methemoglobin (MetHb) usually represents less than 1% of the total
Hgb, but in the case of methemoglobinemia that can be congenital or
induced by some IV dyes, antibiotics (such as sulphas), inhaled gases,
etc., this level increases sharply. Methemoglobin may cause inaccurate

- Intravascular dyes (such as indocyanine green, methylene blue, etc.) at
certain concentrations may cause inaccurate SpO
certain concentrations may cause inaccurate SpO

-Nail polish and artificial nails may cause inaccurate readings.
Physiological characteristics:
Some physiological characteristics may cause decreased perfusion
and/or low signal strength and may potentially cause inaccurate SpO

readings:
- Cardiac arrest, hypotension, shock, severe vasoconstriction, severe
anemia, hypothermia, venous pulsations, congestions, darkly
pigmented skin, ventricular septal defects (VSDs)
Environmental conditions:
Some environmental conditions may cause interference or artifact and
may potentially cause inaccurate SpO

- Excessive ambient light sources (e.g., infrared heat lamps, strobe
lights, bilirubin lights, direct sunlight, operating room lights). To prevent
such interference, cover the sensor with opaque material.
- Electrical interference/Electrosurgery
- Defibrillation - May cause inaccurate reading for a short amount of
time.
- Excessive patient/sensor motion. Artifact can simulate an SpO

- Electrical interference/Electrosurgery
- Defibrillation - May cause inaccurate reading for a short amount of
time.
- Excessive patient/sensor motion. Artifact can simulate an SpO
2
reading, so that the monitor fails to sound an alarm. In order to ensure
reliable patient monitoring, the proper application of the probe and the
signal quality must be checked at regular intervals.
Sensor placement:
- Sensor placement on the same extremity as a blood pressure cuff,
arterial catheter or intravascular line; or arterial occlusion proximal to
the sensor; or a sensor below the heart level may cause decreased
perfusion and/or low signal strength and potentially cause inaccurate
SpO
