The following general points will aid in ensuring monitoring success.
■
Place the sensor on a site that 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 (electro-surgical device, for
example).
■
Read the sensor Directions for Use for proper sensor application.
MASIMO PULSE CO-OXIMETRY SENSORS
Before use, carefully read the Masimo sensor Directions for Use.
Use only Masimo sensors for pulse oximetry or pulse CO-Oximetry measurements.
Tissue damage can be caused by incorrect application or use of a 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 SENSORS. DO NOT USE A SENSOR WITH EXPOSED
OPTICAL OR ELECTRICAL COMPONENTS. DO NOT IMMERSE THE SENSOR
IN WATER, SOLVENTS, OR CLEANING SOLUTIONS (THE SENSORS AND CON-
NECTORS ARE NOT WATERPROOF). DO NOT STERILIZE BY IRRADIATION,
STEAM, AUTOCLAVE OR ETHYLENE OXIDE UNLESS OTHERWISE INDICATED
IN THE SENSOR DIRECTIONS FOR USE. SEE THE CLEANING INSTRUCTIONS
IN THE DIRECTIONS FOR USE FOR ALL MASIMO REUSABLE 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 IRRA-
DIATION, 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.
NUMERIC DISPLAY - SpO2
Stability of the SpO2 readings may be a good indicator of signal validity. Although stability is a rela-
tive term, experience will provide confidence in 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 averag-
ing 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 device
and reduce the measured variations of SpO2. Inaccurate measurements may be caused by:
■
Elevated levels of Carboxyhemoglobin
■
Elevated levels of Methemoglobin
■
Severe anemia
■
Elevated Total Bilirubin levels
■
Low arterial perfusion
■
Motion artifact
