Frequently asked questions
Is the sensor calibrated to ensure accuracy?
Yes, each SleepSense Piezo Crystal Effort Sensor is individually calibrated to ensure consistent sensitivity, providing reliable and accurate readings.
Can this sensor be used as an apnea monitor?
No, this device is for diagnostic purposes only and is not intended for use as an apnea monitor. It provides respiration waveforms for analysis by qualified professionals.
Is a prescription required for this sensor?
Yes, this device requires a prescription, as it is for professional use only and must be sold by or on the order of a physician. For support, you can contact (888) 757-7367.
How does this sensor connect to a recording device?
This sensor is compatible with any recorder or polygraph device that utilizes an AC low-level channel input.
Key connection specifications include:
- Cable Length: 6’7”
- Connector Type: 1.5 mm touch-proof connector
What are the typical polygraph settings?
The typical polygraph settings recommended for use with the SleepSense Piezo Crystal Effort Sensor ensure optimal signal quality:
- Sensitivity: 100 to 300 µV / mm
- Low Frequency Filter (LFF): 70 Hz
- High Frequency Filter (HFF): 0.1 Hz
This sensor is engineered to provide a very strong and stable signal output, typically achieving an amplitude of 1 mV peak to peak.
Is the effort sensor secure and built robustly?
The SleepSense Piezo Crystal Effort Sensor is engineered for reliable, professional diagnostic use with several robust features and secure fastening methods.
- Secure Fastening: The sensor utilizes double velcro tabs to ensure a firm and reliable attachment to the patient’s chest or abdomen during polysomnography (PSG).
- Robust Construction: The piezo crystal is housed in a durable ABS box with a sturdy mechanical build designed for repeated clinical use.
- Signal Reliability: It features an isolated element, providing excellent immunity to environmental artifacts and guaranteeing a stable, high-quality analog voltage waveform. The system utilizes safety DIN connectors and a 1.5 mm touch-proof connector for secure integration.
How does the sensor prevent interference from environmental factors?
The sensor’s isolated element provides excellent immunity to environmental artifacts, ensuring accurate readings even in challenging monitoring environments.
What is the warranty period for the SleepSense Piezo Crystal Effort Sensor?
The SleepSense Piezo Crystal Effort Sensor is covered by a 1-year warranty against manufacturing defects.
What is the physical size of the sensor?
The main sensor unit, which houses the Piezo crystal, is compact, measuring 3 inches side to side. The entire sensor assembly is designed to be lightweight, weighing approximately 3 oz.
What is the typical strong signal amplitude?
The SleepSense Piezo Crystal Effort Sensor is designed to deliver a very strong and stable signal, utilizing Piezo-electric technology to convert respiratory movement into an analog voltage.
The typical signal amplitude output is 1 mV peak to peak.
Note that the actual response recorded is dependent on external factors, including:
- Sensor position and strap tension on the patient
- The characteristics and settings of the connected polygraph equipment
- The polygraph’s sensitivity setting (typically 100 to 300 µV / mm)
