Frequently Asked Questions.

• Is the Sunrise sensor FDA approved?

  Yes, the Sunrise version 1 and version 2 sensors are FDA approved for diagnosing sleep apnea in adults aged 18 years and above.

• What does the Sunrise sensor measure?

  The Sunrise sensor measures 6 signals including airflow from the nose and mouth, mandibular jaw movements (via an accelerometer and gyroscope), pulse rate, SpO², and head position.

• Does the sensor allow for multi-night testing?

  Yes, the Sunrise v2 mult-night sensor allows for up to 3 sleep sessions for 10 hours each over the course of a two-week period. These sleep sessions can be consecutive or non-consecutive.

• Can the Sunrise sensor differentiate between obstructive and central events?

  Yes, the reports provides cAHI and oAHI. The raw data marks periods of obstruction when the jaw opens (mandible drops as measured by the accelerometer) while at the same time there is a significant increase in the amplitude of the mandibular movements denoting increasing effort to breathe (rotation of the jaw as measured by the gyroscope). Central events also reveal a jaw opening (mandible drops as measured by the accelerometer) while simultaneously there is a decrease or complete absence of the amplitude of the mandibular movements (absence or significant decrease in the rotation of the jaw as measured by the gyroscope).

• How does the Sunrise sensor differentiate wake from sleep?

  Wakefulness is clearly discriminated and can be confirmed via visual inspection of the raw data of mandibuar jaw movements due to their highly variable, often fast, and unpredictability in both amplitude and frequency. This was demonstrated in a validation set of 226 simultaneous synchronized PSG recordings with a sensitivity of 88% (95% CI, 71–99%) and a specificity of 94% (85–98%).

• How does the Sunrise automatic scoring compare to PSG for REM sleep detection?

  During REM sleep, mandibular jaw movements are preserved but show marked variability in amplitude and frequency that is characteristically unpredictable. The algorithm performed well in detecting REM sleep with a sensitivity of 83% and a specificity of 89% when compared to simultaneous PSG on 1026 patients.

• Are there patients that should not be tested using the Sunrise sensor?

  In general noting the FDA approved age of 18 years or older, the only patients that would not be candidates for testing with the sensor are bearded individuals that are unwilling to shave the area just below their lip (often referred to as the soul patch) or patients with conditions affecting the rotation of the condyle in the temporo-mandibular joint.

• Do you offer a recycling program?

  Yes, a prepaid return shipping envelope is included in every Sunrise sensor box for the purposes of recycling.
