Respiration Effort Sensor (ActiveThree)

This Respiration Effort Sensor is specially designed to work with the ActiveThree EEG system from BioSemi. It is a piezo-crystal based respiration sensor for measuring changes in thorax or abdominal circumference. The respiration belt comes pre-assembled with a 2m connection cable that terminates in a 6-pin Touchproof (TP) connector.

Piezo-Crystal based respiration effort sensors convert thorax (chest) or abdominal respiration movement to a small analog voltage that provides a clear, reliable indication of respiration waveforms. The sensor may be connected to any AC (low-level) channel on the biosignal acquisition system.

• Piezo-Crystal Respiration Effort Sensor, Adult size, Double Loop
• Large (L) Stretch Band (132cm x 3.81cm)

Application Notes

Positioning the Sensor

1. Select the proper size band for the patient.
2. Strap the sensor bands around the patient’s abdomen or chest, over the nightclothes. Make sure the sensors do not touch the skin.
3. Select the area on the chest/abdomen where the bands will not slide out of place during the night. The sensor box should be slightly off the center line of the body. * When using double tab sensors, make a small “wave” of loose band under the sensor.
4. Gently tighten the bands to secure them in place. There will be interference, (noise) with the signal if the bands are too tight or too loose.
5. Tape the cable approximately five inches away from the sensor to reduce strain and enhance reliability.
6. Check that clear, strong signals are being transmitted before leaving the patient.

Cleaning the Sensor

1. Wipe the sensor and cable with a non-corrosive (to plastic) cleanser to clean before use.
2. Make sure the complete sensor assembly is thoroughly dry before reusing it.
3. Do not soak the sensor in disinfectants.
