Sensor Somatic Site Selection
Select the sensor site over the tissue area of interest (site selection will determine which body
region is monitored). Avoid placing the sensor over thick fatty deposits, hair, or bony protuber-
ances. Do not place the sensor over nevi, hematomas, or broken skin, as this may cause readings
that are not reflective of tissue or no readings at all. When two somatic site sensors are placed,
they must be connected into the preamplifier. Sensor location is at the clinician’s discretion, pro-
vided it adheres to the criteria noted on the instructions for use inside carton. Placements
may include the following locations:
•
Over the spine (upper and lower)
•
On the lateral or posterior calf
•
The upper arm or leg
•
On the forearm
•
On the chest
•
Posterior flank (T10-L2, right or left of midline)
