• 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.
• 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.
• Venous pulsations may cause erroneous low readings (e.g. tricuspid value regurgitation, Trendelenberg position).
• The sensor should be free of visible defects. Never use a damaged sensor or one with exposed electrical circuitry.
• Carefully route cable and patient cable to reduce the possibility of patient entanglement or strangulation.
• If using pulse oximetry during full body irradication, 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.
• 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.
• To prevent damage, do not soak or immerse the connector 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 reprocess 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 8,760 hours of patient monitoring time. Replace the sensor when the
patient monitoring time is exhausted.
INSTRUCTIONS
A) Site selection
• The preferred measuring sites are either the ear lobe or pinna.
• The site should be free 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. To improve perfusion to the ear, rub the earlobe vigorously for 25-30 seconds. The ear lobe can also be rubbed with
rubefacient cream (10-30% methylsalicylate and 2-10% menthol).
CAUTION: Do not use strong vasodilator creams such as nitroglycerine paste.
2. Refer to Fig. 1. Clip the sensor onto the ear lobe or pinna. Orient the cable so that it runs down the neck toward the
body. If the TC-I sensor does not fit properly on the ear, consider using a Masimo disposable sensor or reusable finger
clip sensor on another measuring site.
CAUTION: Discontinue use of the TC-I sensor if there is loss of spring tension sufficient enough to allow slippage or movement
of the sensor from its proper position on the ear lobe or pinna.
CAUTION: Avoid positioning the patient so that external pressure is applied to the sensor at the measuring site.
C) Attaching the sensor to the patient cable
M-LNCS connector
1. Refer to Fig. 2. Orient sensor connector to patient cable connector as shown.
2. Refer to Fig. 3. Insert sensor connector completely into patient cable connector. Close sensor connector cover over
patient cable connector until it locks in place.
LNCS connector
1. Refer to Fig. 4. Insert the sensor connector completely into the patient cable connector.
2. Refer to Fig. 5. Completely close the protective cover.
LNOP connector
1. Refer to Fig. 6. Orient the connecting tab so that the "shiny" contacts are facing up and mate the logo to the logo on
the patient cable.
2. Insert the LNOP connector into the patient cable connector until there is a tactile or audible click of connection. Gently
tug on the connectors to ensure a positive connection. Tape may be used to secure the cable to the patient for ease
of movement.
