Before use, carefully read the sensor Directions for Use.
Use only Masimo oximetry sensors for SpO
2
measurements. Other oxygen transducers
or sensors may cause improper Radical performance.
Tissue damage can be caused by incorrect application or use of a Masimo 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 OR PATIENT CABLES. DO NOT USE A
SENSOR OR PATIENT CABLE WITH EXPOSED OPTICAL OR ELECTRICAL
COMPONENTS.
■
DO NOT IMMERSE THE SENSOR OR PATIENT CABLE IN WATER, SOLVENTS,
OR CLEANING SOLUTIONS (THE SENSORS AND CONNECTORS ARE NOT
WATERPROOF)
■
UNLESS OTHERWISE SPECIFIED, DO NOT STERILIZE SENSORS OR PATIENT
CABLES BY IRRADIATION, STEAM, AUTOCLAVE OR ETHYLENE OXIDE. SEE
THE CLEANING INSTRUCTIONS IN THE DIRECTIONS FOR USE FOR
REUSABLE MASIMO SENSORS.
■
DO NOT ATTEMPT TO REPROCESS, RECONDITION OR RECYCLE ANY
MASIMO SENSORS OR PATIENT CABLES AS THESE PROCESSES MAY
DAMAGE THE ELECTRICAL COMPONENTS, POTENTIALLY LEADING TO
PATIENT HARM.
■
ALL SENSORS AND CABLES ARE DESIGNED FOR USE WITH SPECIFIC
MONITORS. VERIFY THE COMPATIBILIY OF THE MONITOR, CABLE AND
SENSOR BEFORE USE, OTHERWISE PATIENT INJURY CAN RESULT.
SELECTING A MASIMO SET SENSOR
When selecting a sensor, consider, the patient’s weight, the adequacy of perfusion, the
available sensor sites, and the duration of monitoring. For more information refer to the
following table or contact your Sales Representative. Use only Masimo SET sensors and
sensor cables. Select an appropriate sensor, apply it as directed, and observe all
warnings and cautions presented in the directions for use accompanying the sensor.
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 an SpO
2
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.
ANALOG OUTPUT
The Radical can interface with various analog recording devices and/or strip chart
recorders through its Analog Output connector located on the back of the Docking
Station. Depending on the configuration of the Output menu, SpO
2
, pulse rate, pleth
waveform or Signal IQ parameters are output continuously on the Analog 1 and Analog
2 channels. The output signals vary from approximately 0 to 1 volt in a linear fashion.
NOTE:
The actual Analog 1 and Analog 2 output voltage that are generated may not exactly
range between 0.0V to 1.0V. A variance of ± 40 mV is acceptable.
CALIBRATION
For measurement device calibration purposes, the analog output signals can be set to either
0 Volts or 1 Volt in the menu system under Output/Analog Output Mode. Calibrate your
analog recording system to those levels before use.
NURSE CALL
The nurse call feature is available when the Radical is operating in its standalone
configuration. The nurse call feature on the Radical is based on the relay closing or
opening depending on alarm, Low Signal IQ events or both. For maximum flexibility,
either normally open (pin 6) or normally closed (pin 7) signals are available. Only
qualified personnel should connect one of these two signals and common (pin 12) to a
hospital’s nurse call system. During an alarm condition, or a Low Signal IQ event,
depending on the configuration of the output menu, the normally open pin will be
connected to the common pin and the normally closed will be disconnected. In addition
the nurse call polarity can be inverted to accommodate various nurse call stations
requirements.
The nurse call relays have the following electrical specifications per switch:
WARNING:
THE NURSE CALL FEATURE IS DISABLED WHEN THE
AUDIBLE ALARMS ARE SILENCED WHILE THE NURSE CALL
SETTING IN THE OUTPUT MENU IS SET TO “ALARMS”.
