What are breathing disturbances?

Breathing disturbances are referring to interruptions in your sleep patterns. These disturbances, which impairing the restorativeness of sleep, may also be associated with conditions such as sleep apnea.

What is the goal of this feature?

ScanWatch detects breathing disturbances and provides insights to indicate potential signs of sleep apnea. By embedding this new feature, ScanWatch gives access to new preventive health information. And thanks to its self-assessment contents, articles on breathing disorders, and actionable lifestyle tips, Withings empowers users who experience breathing disturbances, to reduce them, or be informed on how they can impact your health.

How does ScanWatch detect breathing disturbances?

ScanWatch is able to detect the presence of breathing disturbances episodes that impact health through a motion sensor, an SpO2 sensor, an HR sensor, which emits and absorbs a light wave passing through blood vessels. With the Respiratory Scan feature, the watch can measure oxygen saturation levels all night long to identify when levels are inadequate due to breathing disturbances such as sleep apnea.

Apart from sleep apnea detection, what is SpO2 for?

Oxygen saturation (SpO2) is a measurement of how much oxygen your blood is carrying as a percentage of the maximum it could carry. For a healthy individual, normal SpO2 should be between 90% and 100%. 

Normally, if a person has a SpO2 below 90, they run the risk of developing hypoxemia. Symptoms may include shortness of breath, especially during brief exercise or even while you are at rest.

The oximeter is non-invasive and painless and is often recommended by doctors because it can be an indicator of certain diseases such as COPD (chronic obstructive pulmonary disease), asthma, pneumonia, lung cancer, heart attack or heart failure.

What is the difference between monitoring breathing disturbances through SpO2 and the technology used in Withings Sleep for sleep apnea? Which technology is more accurate?

These two products use two different techniques:

  • Withings Sleep uses respiratory and cardiac rhythm: It provides sleep analysis close to polysomnography, the medical gold standard for sleep monitoring.
  • ScanWatch uses a SpO2 sensor: This sensor is a non-invasive method of measuring oxygen saturation in the blood, along with advanced machine learning, to make breathing disturbances detection possible.
