Frequently asked questions
What components are included in the Effort Sensor Kit?
The SleepSense Piezo Crystal Effort Sensor Kit (#1388-Kit) is a complete package designed specifically for professional diagnostic respiratory monitoring.The kit includes the following components: * One Piezo Crystal Effort Sensor: This sensor uses Piezo-electric technology housed in a durable ABS box to convert chest or abdominal movement into a high-quality analog voltage waveform. * Two Elastic-Velcro Bands: These are supplied for securely fastening the sensor to the patient during a sleep study. * Safety DIN Connectors: Included to ensure safe and compatible connection to polygraph or data acquisition systems.
Is this sensor designed for professional diagnostic use?
Yes, the SleepSense Piezo Crystal Effort Sensor Kit is designed exclusively for professional diagnostic use, specifically for capturing high-fidelity respiratory effort waveforms in clinical settings and sleep laboratories. This product requires use by or on the order of a physician (RX required).
Intended Use Details:
- It utilizes a Piezo-electric crystal to translate chest or abdominal movement into a clear, reliable analog voltage signal.
- It provides a very strong and stable signal for accurate recording of respiratory effort mechanics in compatible polygraph systems.
Important Limitation: This sensor is strictly for diagnostic recording and must not be utilized as a standalone apnea monitor.
How does the sensor ensure accurate data collection?
The sensor is engineered for high accuracy and signal quality through several key features:
- Isolated Element: The design provides excellent immunity to environmental artifacts (noise) that could interfere with the signal.
- Individual Calibration: Each sensor is individually calibrated to ensure consistent and reliable sensitivity across all units.
- Durable Housing: The Piezo crystal is housed in a sturdy ABS box, contributing to a reliable, stable signal.
What polygraph settings are typically recommended?
The SleepSense Piezo Crystal Effort Sensor works optimally when connected to typical polygraph equipment configured with the following settings:
- Typical Polygraph Sensitivity: 100 to 300 µV / mm
- Typical Polygraph Low Frequency Filter: 70 Hz
- Typical Polygraph High Frequency Filter: 0.1 Hz
When using these settings, the typical signal amplitude produced by the sensor is approximately 1 mV peak to peak. This amplitude may vary depending on the sensor’s precise placement and tension.
Is sensor calibration done individually?
Yes, every SleepSense Piezo Crystal Effort Sensor is individually calibrated by the factory. This rigorous process is a key feature that guarantees:
- Consistent Sensitivity: It ensures uniform sensitivity across all units, typically ranging from 100 to 300 µV/mm when connected to standard polygraph equipment.
- Reliable Data: This consistency is essential for professional diagnostic use, ensuring high-fidelity and reliable analog voltage waveforms for accurately capturing respiratory effort.
Is this sensor suitable for home use or professional medical environments?
This device is intended for professional use only and is for sale by or on the order of a physician only. It is designed for diagnostic purposes and not for use as an apnea monitor.
What are the physical dimensions and weight of the sensor?
The sensor’s dimensions are approximately 3” side to side, with a cable length of 6’7”. It weighs about 3 oz.
What type of connector does the SleepSense Piezo Crystal Effort Sensor use?
The SleepSense Piezo Crystal Effort Sensor connects via a 1.5 mm touch-proof connector.
Does this sensor provide a strong, stable signal?
Yes, this sensor is engineered for high signal quality. It utilizes an isolated Piezo-electric crystal element to provide a very strong and stable analog voltage waveform. This design offers excellent immunity to environmental artifacts, ensuring reliable and clear respiratory effort recordings.
