Sensor Site Selection
The rSO
2
sensor can be placed on the proper cerebral or somatic site.
■ Cerebral site selection: select sensor site on the right and/or left side of forehead. Placement of the sensor
in other cerebral locations, or over hair, may cause inaccurate readings.
■ Somatic site selection: select sensor site over tissue area of interest (site selection will determine which
body region is monitored)
CAUTION
• For cerebral site selection, do not place the sensor over nevi, sinus cavities, the superior sagittal
sinus, subdural or epidural hematomas, injured skin or other anomalies such as arteriovenous
malformations, as this may cause readings that are not reflective of brain tissue or no readings at all.
• For somatic site selection, avoid placing the sensor over thick fatty deposits, hair or bony
protuberances. Do not place the sensor over nevi, hematomas or broken skin, as this may cause
readings that are not reflective of somatic tissue or no readings at all.
NOTE
• For the somatic site selection, see the instruction for use of corresponding sensor for detailed
information.
