The Loss of Pulse detection SaMD is intended to be used for the detection of loss of pulse using photoplethysmography (PPG) and accelerometer sensors present in a wrist worn consumer wearable device. Upon detection of loss of pulse, when the smartwatch is worn, the feature will prompt haptic and audio alerts and notifications to the user and prompt the user’s compatible hardware to call emergency services if the user is unresponsive to the notifications and alerts. This is an opt-in feature and will be offby default.
A software program intended to be installed on a wearable off-the-shelf smart device with photoplethysmography (PPG) capacities [e.g., smart watch] to recognise the absence of a pulse and notify the wearer with audio, visual or haptic alerts; in the absence of a response from the wearer the software is designed to contact emergency medical services (EMS). It is not intended for real-time patient monitoring.
