SleepSense Alice 6 Reusable Thermistor Flow Sensor

Yes, the SleepSense Thermistor Flow Sensor is fully compatible and specifically designed for professional use with the Philips Respironics Alice 6 Diagnostic Sleep System.

Key details regarding compatibility and usage:

• Accurate Monitoring: The sensor uses heat-sensitive elements (three prongs) to measure respiration airflow changes by detecting temperature variations between inhaled and exhaled air.
• Reusable Design: It is engineered for repeated use, offering cost efficiency over disposable types. The sensor is built around a durable, rounded TPE center.
• Signal Output: When connected to the Alice 6 system (or a specific interface box), it provides an analog voltage signal of approximately 1 mV.

The SleepSense Alice 6 Reusable Thermistor Flow Sensor is compatible with the Philips Respironics Alice 6 unit. This ensures proper function and accurate data collection during sleep studies.

The SleepSense Alice 6 Reusable Thermistor Flow Sensor provides a strong and reliable indication of respiration airflow by measuring temperature changes of inhaled and exhaled air. This ensures accurate data for diagnostic sleep studies.

For accurate signal processing and optimal performance with the Philips Respironics Alice 6 system, the following filter settings are recommended for the SleepSense Thermistor Flow Sensor:

• Recommended High Pass Filter Setting: 0.1 Hz
• Recommended Low Pass Filter Setting: 70 Hz

Using these specific settings is essential for maintaining the clarity and integrity of the respiration airflow signal. The sensor converts this airflow data into an analog electrical voltage, typically providing an output of approximately 1 mV when connected through the necessary interface.

The SleepSense Flow Sensor requires adherence to specific environmental conditions to maintain accuracy and device longevity. All humidity requirements are non-condensing.

Operating Conditions

• Temperature: 40 to 104 °F (5 to 40 °C)
• Humidity: 5 to 95%

Storage Conditions

• Temperature: -4 to 140 °F (-20 to 60 °C)
• Humidity: 5 to 95%

Yes, the SleepSense Alice 6 Reusable Thermistor Flow Sensor is designed for simple maintenance and repeated use in clinical settings.

• Reusable Design: The sensor is specifically intended for repeated use, which simplifies the clinical workflow for sleep studies.
• Maintenance: It is noted for being easy to use and clean, helping to maximize efficiency in professional environments.

This product is intended for professional use only and should be purchased or ordered by a physician or under their direction. This ensures proper and safe use within a clinical setting.

The SleepSense Alice 6 Sensor accurately monitors respiration by detecting temperature fluctuations between inhaled and exhaled air. The type of signal output generated depends on how the sensor is connected to the diagnostic system:

• When used with an Interface Box (e.g., the SleepSense interface box or the main PSG System): The sensor provides a strong, reliable analog electrical voltage signal, typically outputting approximately 1 mV.
• When used without an Interface Box: The output is characterized by an NTC Ω change (Negative Temperature Coefficient resistance change), which reflects the thermal resistance fluctuation detected by the heat-sensitive elements.

The SleepSense Flow Sensor accurately monitors respiration using thermistor technology, which detects temperature changes associated with the breathing cycle. This provides a clear and reliable signal for clinical analysis.

Here is how the detection mechanism works:

• Detection Principle: The sensor utilizes three heat-sensitive thermistor elements located on its prongs, positioned under the patient’s nostrils.
• Measurement: These elements measure the temperature differential between the cooler inhaled air and the warmer exhaled air.
• Signal Output: This fluctuation is converted into a reliable analog electrical voltage signal that is directly proportional to the detected airflow changes.
• Performance: When integrated with the Philips Respironics Alice 6 system, the sensor generates a consistent signal output of approximately 1 mV (with the interface).

The product includes the reusable Thermistor Flow Sensor unit with its attached cable and connector, ready for use with the Alice 6 Diagnostic Sleep System.
