The Respiratory Scan will measure your heart rate, respiratory rate and oxygen saturation level throughout the night to provide complete maps of your sleep.

During sleep, it is possible to experience trouble breathing and you may not remember it in the morning. Oxygen saturation level drops can be a sign of these breathing disturbances. When the brain senses that oxygen levels are getting too low, it triggers a safety alarm signal, waking you up to take a breath. After falling back to sleep, this can occur repeatedly during the night, which doesn’t allow the body to recover properly.

ScanWatch embeds sensors to scan your night. It uses its PPG (photoplethysmography) sensor to measure your heart rate and heart rhythm, your breathing rate and respiratory effort, and your oxygen saturation (SpO2) continuously. It also uses an accelerometer to monitor your actigraphy (rest and activity cycles). Consequently, ScanWatch can detect breathing disturbances episodes during your sleep.

When activating the Respiratory Scan, you will be able to choose between three types of experience:

  • Off: No Respiratory Scan will be launched.
  • Automatic: Based on the results of the first night, ScanWatch will repeat the recording when necessary. It will notify you the day before and ask if you want to reschedule later. This frequency is recommended by doctors to get the best results from this feature. Note that the battery should be above 10% to launch the series of measurements.
  • Always on: A Respiratory Scan will be completed every night, and you will get the results every morning. Your battery life might suffer from this mode.

Understanding my results

ScanWatch provides three categories to grade the severity of breathing disturbances:

  • 0 to 30 - Few : A few breathing disturbances were detected on the last tracked night.
  • 30 to 60 - Moderate : A moderate amount of breathing disturbances were detected on the last tracked night.
  • 60 to 100 - High : A high volume of breathing disturbances were detected on the last tracked night.

Medical advice should be sought if you experience moderate or severe breathing disturbances, or if you experience symptoms and have concerns.

Sharing my results

You can find each night scan record and history in the Health Mate app and you can easily share it as a PDF with a doctor or a healthcare professional. This can help you assist with early diagnosis and prevention in case of breathing disturbance detection.

Notes

  • The Respiratory Scan functionality will impact the battery life of the watch.
  • When the Respiratory Scan is activated, a moon icon appears under the time on the screen of the watch.
  • ScanWatch is not intended to diagnose apneic episodes or assist with a diagnosis. Please seek medical advice if you need a personal sleep apnea diagnosis.
