• 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.
• Do not use the sensor during MRI scanning or in a MRI environment as it may result in physical harm.
• 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.
• 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 readings may be caused by EMI radiation interference.
• Abnormal fingers, Intravascular dyes such as indocyanine green or methylene blue or externally applied coloring and
texture such as nail polish, acrylic nails, glitter, etc. may lead to inaccurate or no readings.
• 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 Carboxyhemoglobin (COHb) may lead to inaccurate SpO
• Elevated levels of Methemoglobin (MetHb) may lead to inaccurate SpO
• Elevated levels of total bilirubin may lead to inaccurate SpO
• Inaccurate SpO readings may be caused by severe anemia, very low arterial perfusion, or extreme motion artifact.
2
• Hemoglobinopathies and synthesis disorders such as thalassemias, Hb s, Hb c, sickle cell, etc. may cause inaccurate
SpO readings.
2
• Inaccurate SpO readings may be caused by vasospastic disease such as Raynaud's, and peripheral vascular disease.
2
• Inaccurate SpO readings may be caused by elevated levels of dyshemoglobin, hypocapnic or hypercapnic conditions
2
and severe vasoconstriction or hypothermia.
• SpO readings may be affected under very low perfusion conditions at the monitored site.
2
• Readings provided with a low signal confidence indicator may not be accurate.
• Do not modify or alter the sensor in any way. Alteration or modification may affect performance and/or accuracy.
• Clean the sensors prior to reuse on multiple patients.
• 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 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 while monitoring consecutive patients 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 8,760 hours of patient monitoring time. Replace the sensor when
the patient monitoring time is exhausted.
INSTRUCTIONS
A) Site Selection
• Choose a site that is well perfused and least restricts a conscious patient's movements. The ring finger of the
non-dominant hand is preferred. Alternatively, the other digits on the non-dominant hand may be used.
• Always choose a site that will completely cover the sensor's detector window. The great toe or long toe (next to the great
toe) may be used on restrained patients or patients whose hands are unavailable.
• Site should be cleaned of debris prior to sensor placement.
CAUTION: Before using the sensor, ensure that the sensor is physically intact, with no broken or frayed wires or damaged parts.
B) Attaching the sensor to the patient
1. Refer to Fig. 1. Open the sensor by pressing on hinge tabs. Place the selected digit over the sensor window of the DCI
or DCI-P. The fleshiest part of the digit should be covering the detector window in the lower half of the sensor. The
top half of the sensor is identified by the cable. On a finger site, the tip of the finger should touch the raised digit stop
inside the sensor. If the fingernail is long, it may extend over and pass the finger stop.
2. Refer to Fig. 2. The hinged tabs of the sensor should open to evenly distribute the grip of the sensor along the length
of the finger. Check position of sensor to verify correct positioning. Complete coverage of the detector window is
needed to ensure accurate data.
3. Refer to Fig. 3. Orient the sensor so that the cable will be running towards the top of the patient's hand.
NOTE: With smaller digits, in order to completely cover the detector window, it may be necessary to use a lower weight
range sensor. The sensor is not intended for use on the thumb or across a child's hand or foot.
