• Inaccurate readings may be caused by birthmark(s), tattoos, or skin discolorations in sensor path, moisture on the skin,
deformed fingers, misaligned sensor emitter and detector, EMC interference from other sensors attached to the patient,
and objects blocking the light path.
• Avoid placing the sensor on any extremity with an arterial catheter or blood pressure cuff.
• Carefully route cable and patient cable to reduce the possibility of patient entanglement or strangulation.
• 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, Trendelenburg position).
• Inaccurate SpO , SpHb, and SpMet readings may be caused by abnormal venous pulsation or venous congestion.

• If using pulse oximetry during full body irradiation, keep the sensor out of the radiation field. If sensor is exposed to the
radiation, the reading might be inaccurate or the unit might read zero for the duration of the active radiation period.
• High ambient light sources such as surgical lights (especially those with a xenon light source), bilirubin lamps,
fluorescent lights, infrared heating lamps, and direct sunlight can interfere with the performance of the sensor.
• High intensity extreme lights (such as pulsating strobe lights) directed on the sensor, may not allow the Pulse
CO-Oximeter® to obtain vital sign readings.
• To prevent interference from ambient light, ensure that the sensor is properly applied, and cover the sensor site with
opaque material, if required. Failure to take this precaution in high ambient light conditions may result in inaccurate
measurements.
• Inaccurate SpHb and SpMet readings can be caused by extreme hemoglobin levels, low arterial perfusion, or motion
artifact.
• Inaccurate SpHb and SpMet readings can be caused by extreme hemoglobin levels, low arterial perfusion, low arterial
oxygen saturation levels including altitude induced hypoxemia, motion artifact.
• The pulsations from intra-aortic balloon support can affect the pulse rate displayed on the oximeter. Verify patient's
pulse rate against the ECG heart rate.
• Venous pulsations may cause erroneous low SpO2 readings (e.g. tricuspid valve regurgitation, Trendelenburg position).
• Inaccurate SpO2 readings may be caused by severe anemia, very low arterial perfusion, or extreme motion artifact.
• Hemoglobinopathies and synthesis disorders such as thalassemias, Hb s, Hb c, sickle cell, etc. may cause inaccurate SpO
SpHb, and SpMet readings.
• Inaccurate SpO , SpHb, and SpMet readings may be caused by vasospastic disease such as Raynaud's, and peripheral
2
vascular disease.
• Inaccurate readings may be caused by EMI radiation interference.
• Inaccurate SpO , SpHb, and SpMet readings may be caused by elevated levels of dyshemoglobin, hypocapnic or
2
hypercapnic conditions and severe vasoconstriction, or hypothermia.
• With very low perfusion at the monitored site, the reading may read lower than core arterial oxygen saturation.
• SpHb and SpMet readings may be affected under low perfusion conditions at the monitored site.
• Inaccurate SpHb and SpMet readings may be caused by elevated PaO
• Elevated levels of Carboxyhemoglobin (COHb) may lead to inaccurate SpO
• High levels of COHb or MetHb may occur with a seemingly normal SpO
suspected, laboratory analysis (CO-Oximetry) of a blood sample should be performed.
• Elevated levels of Methemoglobin (MetHb) may lead to inaccurate SpO
• Elevated levels of total bilirubin or liver disease may lead to inaccurate SpO
• Do not modify or alter the sensor in any way. Alteration or modification may affect performance and/or accuracy.
• To prevent damage, do not soak or immerse the sensor in any liquid solution.
• Do not attempt to sterilize by irradiation, steam, autoclave or ethylene oxide as it will damage the sensor.
• Do not attempt to reuse on multiple patients, reprocess, recondition or recycle Masimo sensors or patient cables as these
processes may damage the electrical components, potentially leading to patient harm.
• Caution: Replace the sensor when a replace sensor message is displayed, or when a low SIQ message is consistently
displayed after completing the low SIQ troubleshooting steps identified in the monitoring device operator's manual.
• Note: The sensor is provided with X-Cal™ technology to minimize the risk of inaccurate readings and unanticipated loss
of patient monitoring. The sensor will provide up to 168 hours of patient monitoring time or up to 336 hours for sensors
with a replaceable tape. After single-patient use, discard sensor.
