• Carefully route cable and patient cable to reduce the possibility of patient entanglement or strangulation.
• Avoid placing the sensor on any extremity with an arterial catheter or blood pressure cuff.
• 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.
• 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.
• 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) will lead to inaccurate SpO
• Elevated Total Bilirubin levels may lead to inaccurate SpO
• 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 SpO
• Inaccurate SpO readings may be caused by severe anemia, low arterial perfusion or motion artifact.

• To prevent damage, do not soak or immerse the sensor in any liquid solution. Do not attempt to sterilize the sensor.
• Do not modify or alter the sensor in any way. Alteration or modification may affect performance and/or accuracy.
• 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.
• High oxygen concentrations may predispose a premature infant to retinopathy. Therefore, the upper alarm limit for the
oxygen saturation must be carefully selected in accordance with accepted clinical standards.
• 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.
INSTRUCTIONS:
A) Site Selection
• Always choose a site that is well perfused and will completely cover the sensor's detector window.
• Site should be cleaned of debris and dry prior to sensor placement.
Trauma Sensor (Adult)
> 30 kg: The preferred site is the middle or ring finger of the non-dominant hand.
Newborn Sensor (Infant/Pediatric)
3–10 kg: The preferred site is the great toe. Alternatively, the toe next to the great toe, or the thumb can be used.
10–30 kg: The preferred site is the middle or ring finger of the non-dominant hand.
Newborn Sensor (Neonatal)
< 3 kg: The preferred site is the foot. Alternatively, across the palm and back of the hand can be used.
B) Attaching the sensor to the patient
1. Open the pouch and remove the sensor. Remove the backing from the sensor, if present.
ADULTS ( > 30 kg), PEDIATRIC (10–30 kg)
2. Refer to Fig. 1a. Direct the sensor cable so that it runs along the top of the hand or points away from the patient. Position
the detector onto the fleshly part of the finger. Alternatively, the sensor may also be applied to the toe (not shown).
Complete coverage of the detector window is needed to ensure accurate data.
3. Refer to Fig. 1b. Wrap the foam wrap around the finger and ensure that the emitter window (red star) aligns on the top
of the finger directly opposite of the detector.
4. Refer to Fig. 1c. Check the sensor to verify correct positioning and reposition if necessary.
INFANTS (3–10 kg)
2. Refer to Fig. 2a. Direct the sensor cable so that it runs along the bottom of the foot or points away from the patient.
Position the detector onto the fleshly part of the great toe. Alternatively, the sensor may also be applied to the thumb
(not shown). Complete coverage of the detector window is needed to ensure accurate data.
3. Refer to Fig. 2b. Wrap the foam wrap around the toe and ensure that the emitter window (red star) aligns on the top of
the toe directly opposite of the detector.
4. Refer to Fig. 2c. Check the sensor to verify correct positioning and reposition if necessary.
NEONATES (< 3 kg)
2. Refer to Fig. 3a. For fragile skin, the stickiness of the medical grade adhesive can be diminished or eliminated by daubing
the adhesive areas with a cotton ball or with gauze.
3. Refer to Fig. 3b. Direct the sensor cable so that it either points away from the patient or runs along the bottom of the foot.
Apply the detector onto the fleshy part of the lateral aspect sole of the foot aligned with the fourth toe. Alternatively, the
detector may also be applied to the top of the foot (not shown). Complete coverage of the detector window is needed
to ensure accurate data.
