What are breathing disturbances?
Breathing disturbances refer to interruptions in your sleep patterns. These disturbances may impair the restorativeness of sleep.
What is the goal of this feature?
By embedding this new feature, ScanWatch gives access to new preventive health information. Withings also provides self-assessment content, articles on breathing disorders, and actionable lifestyle tips to help users learn how disturbances can impact sleep and what people can do to reduce these instances.
How does ScanWatch detect breathing disturbances?
ScanWatch is able to detect the presence of breathing disturbances through a motion sensor, an SpO2 sensor, and an HR sensor which emits and absorbs light waves 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.
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, for people who have SpO2 levels below 90, they run the risk of developing hypoxemia. Symptoms may include shortness of breath, especially during brief exercise or even while at rest.
The oximeter is non-invasive, painless, and often recommended by doctors because it can detect indicators 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? 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.
