Abstract

The present application discloses an early warning method, device and system of sudden death. The method includes: 1. extracting 6 indicators of 4 types of physiological information 2. performing abnormality detection on the physiological information and calculating an early warning level, proceeding to step 3 when a result of the abnormality detection indicates abnormal, and continuing the abnormality detection when the result of the abnormality detection indicates normal; and 3. producing sound, light and vibration alarms, in which an alarm device is driven to produce sound, light and vibration and provide a corresponding early warning level. A higher early warning level indicates a higher risk of sudden death.
