NUMERIC DISPLAY - PULSE RATE
The Pulse Rate displayed on the Rad-8 may differ slightly from the heart rate displayed
on ECG monitors due to differences in averaging times. There may also be a discrepancy
between cardiac electrical activity and peripheral arterial pulsation. Significant differences
may indicate a problem with the signal quality due to physiological changes in the patient
or one of the instruments or application of the sensor or patient cable. The pulsations
from intra-aortic balloon support can be additive to the pulse rate displayed on the pulse
oximeter.

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 photodetector.
■
Place the sensor on a site that has unrestricted blood flow.
■
Do not select a site near potential electrical interference (electrosurgical unit, for
example).
■
Read the sensor Directions for Use for proper sensor application.
NUMERIC DISPLAY - SpO
2
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 mea-
sured variations of SpO
2
and PR.
MASIMO SENSORS
Before use, carefully read the LNOP, LNOPv and LNCS 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 or
LNCS 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-
NEC TORS 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 INSTRUC-
TIONS IN THE DIRECTIONS FOR USE FOR REUSABLE MASIMO 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 USE ADDITIONAL TAPE TO SECURE SENSOR TO PATIENT.
