Life-Saving Innovation: Loss of Pulse Detection
Loss of pulse detection is a groundbreaking feature introduced on the Pixel Watch 3, designed to monitor heart activity and identify instances of pulselessness. This condition can arise from various medical emergencies, including cardiac arrest or respiratory failure, and the feature aims to offer timely assistance in critical situations. When the watch detects a loss of pulse, it begins a countdown and sends alerts to the user, escalating to a loud notification if the user remains unresponsive. If a true emergency is confirmed, the watch automatically contacts emergency services, providing vital information about the user’s condition and location to facilitate a rapid response.
