SS5LB RESPIRATORY EFFORT TRANSDUCER
The SS5LB transducer is used to record respiration via chest or abdomen expansion and contraction. This
transducer is useful for determining how deeply someone is breathing and for calculating the person’s breathing
rate or respiration rate. The transducer is a strain assembly that measures the change in thoracic or abdominal
circumference. The strap presents minimal resistance to movement and is extremely unobtrusive.
Due to its novel construction, the SS5LB can measure extremely slow respiration patterns with no loss in signal
amplitude while maintaining excellent linearity and minimal hysteresis. The respiratory effort transducer has a 2-
meter flexible lightweight cable. The center plastic housing protects the delicate sensor within.
The transducer is attached by a fully adjustable nylon strap, which allows the transducer to fit almost any
circumference.
To attach the nylon belt to the transducer, thread the strap through the corresponding slots on the sensor assembly.
Place the transducer around the body at the level of maximum respiratory expansion (generally about 5cm below
the armpits). At maximum expiration, adjust the strap so there is slight tension to hold the strap around the chest.
