1.6.9.1 Masimo® Sensors and Patient Cable
Masimo® provides a family of sensors suitable for a wide variety of clinical settings and
patients. Specific sensors have been developed for neonates, infants, children, and adults.
All sensors are indicated for continuous noninvasive monitoring of arterial oxygen saturation
(SpO
2
) and pulse rate. The LNOP DCSC Adult Reuable Spot Check Sensor is used for ‘‘Spot
Check’’ applications. The LNOP® - DC1 Adult Re-usable Finger Sensor can also be used for
“spot check” applications if needed. All sensors are intended for “single-patient use only”
unless indicated as ‘‘reusable’’.
Selecting a Sensor
Sensors are designed for specific sites on patients with designated weight ranges. To select
the appropriate sensor, consider the patient’s weight, level of activity, adequacy of perfusion,
which sensor sites are available and the anticipated duration of monitoring.
Cleaning And Re-use
The sensor may be reattached to the same patient if the emitter and detector windows are
clear and the adhesive still adheres to the skin. The adhesive can be partially rejuvenated by
wiping with an alcohol wipe and allowing the sensor to thoroughly air dry prior to
replacement on the patient.
Performance Considerations
To insure optimal performance, use an appropriate sensor, apply it as directed, and observe
all warnings and cautions.
If excessive ambient light is present, cover the sensor site with opaque material. Failure to do
so may result in inaccurate measurements. Light sources that can affect performance include
surgical lights, especially those with a xenon light source, bilirubin lamps, fluorescent lights,
infrared heating lamps, and direct sunlight.
In the event that you are unable to get any reading, or the reading you get is inaccurate,
consider the following:
• If your patient is poorly perfused, try applying the sensor to another site - such as a
different finger or toe.
• Check that the sensor is properly aligned.
• In electrosurgery, make sure sensor is not too close to ESU devices or cables.
• Check to make sure the site area is clean/non-greasy, clean site and sensor if needed.
Nail polish and fungus should be removed.
• Excessive patient motion can affect readings and may cause a “SpO
2
Interference”
message to be displayed. Encourage the patient to remain still. If this is not possible try
moving the sensor to another site.
If patient movement presents a problem:
