Monitoring
The following general points will aid in ensuring oximetry monitoring success.
■ Place the sensor on a site that is not too thick, has sufficient perfusion and provides
proper alignment of the LED’s and detector.
■ Place the sensor on a site that has unrestricted blood flow.
■ Do not secure a sensor with tape.
■ Do not select a site near potential electrical interference (electrosurgical unit, for
example).
■ Read the sensor Directions for Use for proper sensor application.
MASIMO SENSORS
Before use, carefully read the LNOP, LNOPv, LNCS and Rainbow series sensor Directions
for Use.
Use only Masimo oximetry sensors for SpO
2
measurements.
Tissue damage can be caused by incorrect application or use of an LNOP, LNOPv, LNCS
or Rainbow sensor, for example by wrapping the sensor too tightly. Inspect the sensor site
as directed in the sensor Directions for Use to ensure skin integrity and correct positioning
and adhesion of the sensor.
CAUTIONS
DO NOT USE DAMAGED LNOP, LNOPv, LNCS OR RAINBOW SENSORS. DO NOT
USE AN LNOP, LNOPv, LNCS OR RAINBOW SENSOR WITH EXPOSED OPTICAL
OR ELECTRICAL COMPONENTS. DO NOT IMMERSE THE SENSOR IN WATER,
SOLVENTS, OR CLEANING SOLUTIONS (THE SENSORS AND CONNECTORS
ARE NOT WATERPROOF). DO NOT STERILIZE BY IRRADIATION, STEAM,
AUTOCLAVE OR ETHYLENE OXIDE (UNLESS OTHERWISE INDICATED ON THE
SENSOR DIRECTIONS FOR USE). SEE THE CLEANING INSTRUCTIONS IN
THE DIRECTIONS FOR USE FOR REUSABLE MASIMO LNOP, LNOPv, LNCS OR
RAINBOW SENSORS.
DO NOT USE DAMAGED PATIENT CABLES. DO NOT IMMERSE THE PATIENT
CABLES IN WATER, SOLVENTS, OR CLEANING SOLUTIONS (THE PATIENT
CABLE CONNECTORS ARE NOT WATERPROOF). DO NOT STERILIZE BY
IRRADIATION, STEAM, AUTOCLAVE OR ETHYLENE OXIDE.
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.

Stability of the SpO
2
readings may be a good indicator of signal validity. Although stability
is a relative term, experience will provide a good feeling for changes that are artifactual or
physiological and the speed, timing, and behavior of each. The stability of the readings
over time is affected by the averaging mode being used. The longer the averaging time,
the more stable the readings tend to become. This is due to a dampened response as
the signal is averaged over a longer period of time than during shorter averaging times.
However, longer averaging times delay the response of the oximeter and reduce the
measured variations of SpO
2
and PR.
