Automatically Generating Notifications of Emergency Medical Events

This disclosure describes techniques that enable rapid response to medical events or emergencies by automatically notifying, with user and recipient permission, those nearby with medical knowledge (e.g., family members, neighbors, etc.) of a medical emergency. Nearby medical professionals can immediately initiate assistance procedures, or otherwise alleviate the medical condition, until emergency personnel can arrive. With user permission, the techniques can also leverage nearby devices, e.g., neighboring devices, devices not on the user’s person, etc., to detect medical events (e.g., a fall), via passive detection. The techniques make advantageous and coordinated use of the array of sensors available via wearable devices, IoT devices, smart-home devices, etc., to detect and confirm via multiple modalities, e.g., audio heatmaps, motion-sensing radar, WiFi reflectivity patterns, etc., a medical emergency.
