A smartwatch that controls heart and sleep apnoea


Withings presented at CES in Las Vegas ScanWatch, a new intelligent watch that includes an ECG sensor and Sp02 capabilities.

The watch comes with a PPG sensor, which will continuously monitor the user’s heart rate and alert users if there is an irregularity. If any issues are detected, the watch will prompt the user to take an ECG reading. Watch wearers can read the ECG on the screen of their watch or in the watch’s accompanying Health Mate app. The app can store the reading and any notes that go along with the reading.

Currently, the technology’s ECG feature is being reviewed by the FDA, and the company expects clearance sometime in Q2.

The Sp02 sensor is capable of continuously measuring arterial hemoglobin saturation and, through this, revealing episodes of sleep apnoea, when insufficient airflow to the lungs can cause a drop in blood oxygen levels.

The watch can also monitor sleep patterns and sleep quality. In the morning, users can get a sleep score, which can be accessed through the app.

The new smartwatch has a battery life of 30 days and allows you to track multiple physical exercises including walking, running and swimming (it is waterproof up to 50 m).

Both atrial fibrillation and sleep apnoea are quite common clinical conditions. In the United States, atrial fibrillation affects between 2.7 and 6.1 million people. 5 to 10% of the population suffers from sleep apnoea.

ScanWatch is still under development and will be marketed in the coming months.
