  • How do I know if I have sleeping problems?

    To find out, you need to take a sleep test. You will then have an accurate diagnosis which will allow you to undergo medical treatment if necessary. Sunrise is a certified sleep test for sleep apnea, which allows you to diagnose your sleep from home overnight.
  • Is one night enough for an accurate diagnosis?

    Many people will be able to get a true picture of their sleep after a night of analysis. Nevertheless, the more nights tested the more precise and rich the obtained data is. For people who need or wish to repeat the test over several nights because they know that there are nights when they sleep better than others, it is better to buy 2 or 3 sensors.
  • Is the Sunrise sleep test the same as a hospital sleep test?

    Sunrise is a certified medical device using a new technology for sleep analysis. It is accepted by healthcare professionals, sleep specialists and other doctors. Sunrise has been clinically tested and proven comparatively accurate up to 90% to the PSG (polysomnography), the standard hospital sleep test.
  • What exactly does the Sunrise sensor measure?

    When placed on the chin, the Sunrise sensor measures mandibular movements. The contraction of the muscles attached to the mandible (the bone of the jaw) is a signal sent from the brain in order to control the passage of air through the upper airways. By capturing these mandibular movements and associating it with our algorithm, the sensor is able to provide various respiratory measurements necessary to make a diagnosis of sleep-related breathing disorders, such as sleep apnea or hypopnea (snoring).
  • How does the Sunrise sleep test work?

    Sunrise aims to make sleep testing as simple as having a good night's sleep! Our sensor is certified for the diagnosis of sleep apnea. Connect the small sensor with your smartphone via the Sunrise App (free) and stick it on your chin before going to sleep. The sensor will record all needed information during your sleep for creating a report that you receive when you wake up, directly on your smartphone! You may then choose to share these results with your doctor or get an appointpent with one of our partner sleep specialists to start treatment if it is needed. Easy!
  • I cannot find how to order the Sunrise sleep test?

    To place an order for the Sunrise test, simply click on the "Order now" button at the top right of your screen. If prices appear to be displayed incorrectly due to geolocation redirection, you may contact us directly and we will help you in more detail.
  • After I woke up from my test night, I did not receive my results. What should I do?

    It takes a few moments for the application to generate the report. If the status appears as "Pending", please check your internet connection. If the status has been "Analyzing" for more than 48 hours, contact us.
  • Is there an expiration date for using the Sunrise sensor?

    You can find the expiration date on the label on the back of the box. This has been defined in order to ensure the performance of our device. Beyond this date, we can no longer guarantee that the sensor will still be functional, whether in terms of its battery or the adhesives that compose it.
  • Is there a warranty?

    Yes, Sunrise will replace the sensor and / or accessories free of charge if they are faulty on delivery.
  • How do I attach the sensor?

    It is very simple! Remove the protective cover of the adhesive on the back of the sensor to activate it. Then place it horizontally in the middle of your chin. For bearded people, we advise to shave or use the extra adhesive strips provided in the box to ensure optimal fixation. A short step-by-step guide with photos in the application will help direct you in the right way.
  • What do I need in order to use Sunrise?

    In addition to the sensor, which you can order from the website, Sunrise requires the use of a smartphone (with Android or iOS). Your smartphone must be charged and have an internet connection (WiFi or 3G) to perform the test and access the results. Make sure there is enough free memory in the phone for you to install the application.

For Therapists

  • Is it possible to differentiate between an obstructive and central event?

    Mandibular movements are directly correlated with respiratory effort. It is the reduction or complete pause (for central events) or increase (for obstructive events) of respiratory effort that shows the difference between obstructive and central apnea events. Therefore, it is possible to make a differentiation based on mandibular movements. The central events produce movements visible on the Sunrise raw signal report. An automatic detection and analysis of central events will be implemented into the report by the end of 2021.
  • Is it possible to differentiate between an apnea and a hyponea?

    It is possible to differentiate apnea from hypopnea on the raw signal report. The amplitude of the mandibular movement changes proportionally to diaphragmatic EMG activity (and esophageal pressure - publication to come) and accurately identifies variations of respiratory effort during normal sleep and SDB (Martinot et al, Frontiers in Neurology, 2017). Consequently, an obstructive apnea event creates a bigger amplitude of mandibular movement than an obstructive hypopnea.
  • Is the accuracy of the device affected by the presence of mouth breathing?

    The Sunrise sensor detects mandibular movements very precisely, regardless of how open the mouth is, as shown by the gyroscope. Mandibular movements are detected even during a greater magnitude of mouth opening, despite their amplitude being reduced. There is no reduction of accuracy with opening of the mouth.
  • Is it possible that change in possition can affect the Sunrise test measurements?

    Mandibular movements have been measured with the algorithm trained and validated on a large number of patients while sleeping in all possible positions. Mandibular movement (generated by the activation of muscles of the upper airway) is preserved no matter the head or body position. This happens physiologically and is important for preservation of respiration during sleep by ensuring stability of the upper airways.
  • What is the added value of Artificial Intelligence?

    A computer is able to analyse events that an experiencesd lab. technician scorer would need years to learn. The advantage is that such analysis becomes free of the human factor and is very sensitive. It permits to detect small variations in terms of signal frequency and amplitude. This automatic analysis acts as a decision tool for the clinician who is able to review the analysis by themselves and access the raw data.
  • What happens if the patient has a beard?

    Extra adhesive is provided for better fixation on a stable/ few day beard. For beards that are very thick, the patient is advised to shave.
  • Can this be scored manually?

    It is possible to export the raw data in an .edf format to manually score the signal in an .edf viewer of your choice.
  • Is Sunrise able to measure snoring?

    For now, there is no microphone for snoring detection. However, the presence of respiratory effort provides information about snoring. This measurement can indeed be an indicator of snoring when it is not associated with respiratory disturbance.
  • Is Mandibular Movement affected by the presence of a TMJ condition?

    The movements remain even in the presence of a pathology of the temporomandibular joint cartilage and often it is the chewing movements (not breathing) that are painful, especially when they are extreme. These often occur during the state of wakefulness and not sleep. Respiratory movements are only affected in advanced ankylosis of the joint which is very rare. In practice there is no interference with TMJ pathologies.
  • What does the measurement of Respiratory effort mean?

    Respiratory effort is the percentage of sleep time experiencing breathing difficulties to a level that it can lead to daytime sleepiness. When respiratory effort is not associated with breathing disturbances it can be an indicator of snoring. The presence of a % of respiratory effort during the night is an important new parameter for certain clinical situations such as upper airway resistance syndrome. In such cases, there is a weak AHI but a significant respiratory effort during the night, especially during the 3 and 4 stages of sleep. It is also interesting when in children where AHI is low for most of them, there is an increased respiratory effort regardless of the sleep stage.
  • For how long can the therapist access to the results?

    The therapist has access to view the report for as long as the patient links their account to that of the doctor and/or keeps their data with Sunrise.
  • Is Sunrise reimbursed?

    We are currently in discussion for reimbursement with health authorities in different countries.
  • What is the required minimum sleeping time for the test?

    4 hours of total sleep time is the requirement. In any case, the results are always accessible to the doctor. However, for under 4 hours, a message is displayed specifying that the duration of sleeping time might be insufficient. We apply the same standard as for the PSG.
  • Can Sunrise be used for titration of Mandibular Advancement Devices?

    Sunrise allows the advantage of repeating tests for patients in different clinical situations. It is therefore possible to use Sunrise for a patient with a mandibular advancement appliance and use the residual AHI measurement for adjusting the device.
