Frequently asked questions
How does the Thermistor Flow Sensor measure respiration?
The SleepSense PDX Thermistor Flow Sensor measures respiration airflow by utilizing three internal heat-sensitive elements. It works by detecting the temperature changes between inhaled and exhaled air, producing an analog electrical voltage proportional to these changes. The sensor is specifically designed for and fully compatible with the Philips Respironics PDX monitoring system, and generates a reliable signal output of approximately 1mV (when connected with the required interface).
How does the design of this sensor prioritize patient comfort?
This sensor features a comfortable and sleek design to enhance patient comfort and ensure consistent signal quality throughout the night. The small, rounded TPE center with three prongs is designed to minimize discomfort during use.
How does the sensor ensure reliable respiration monitoring?
The SleepSense PDX Thermistor Flow Sensor utilizes three heat-sensitive elements to provide a clear and dependable indication of respiration airflow via a small analog electrical voltage. This ensures reliable respiration monitoring.
What are the recommended filter settings?
The SleepSense PDX Thermistor Flow Sensor requires specific settings for optimal signal processing:
- High Pass Filter: 0.1 Hz
- Low Pass Filter: 70 Hz (or as recommended by your system instructions)
Using these settings helps ensure a clear and reliable analog electrical voltage output (approximately 1mV with the required interface) that corresponds to respiratory temperature changes.
What are the operating specifications for temperature and humidity?
The SleepSense Thermistor Flow Sensor is designed to operate reliably within specific environmental parameters:
- Operating Temperature Range: 40 to 104 °F
- Operating and Storage Humidity: 5 to 95% (non-condensing)
What is the signal output type for this sensor?
The SleepSense PDX Thermistor Flow Sensor provides an analog electrical voltage signal that is directly proportional to the temperature changes detected during respiration.When connected to the appropriate system input, the output signal specifications are as follows:* With an appropriate interface: The signal output is approximately 1mV.* Without an interface: The sensor measures an NTC
change (Negative Temperature Coefficient Ohms change).
Is this sensor for professional use only?
Yes, the SleepSense PDX Thermistor Flow Sensor is strictly restricted for professional use only.
This ensures the appropriate medical application of the device. Regulatory compliance dictates that this sensor must be sold by or on the order of a physician.
Is the sensor housing made of quality material?
Yes, the center housing for the heat-sensitive elements is constructed from TPE (Thermoplastic Elastomer). This small, rounded structure is designed to promote patient comfort and ensure consistent, reliable signal acquisition during sleep monitoring.
Where should the SleepSense PDX Thermistor Flow Sensor be connected on the system?
This sensor should be connected to the system’s thermal flow input.
Is this sensor compatible with the Philips Respironics PDX unit?
Yes, the SleepSense PDX Thermistor Flow Sensor is specifically designed to be fully compatible with the Philips Respironics PDX unit. It connects directly to the thermal flow input of a PDX system.
