Publication number: 20220261731Abstract: Embodiments of this disclosure are directed to a wearable cardioverter defibrillator (“WCD”) system design in which a WCD implements an alert prioritization scheme to provide the patient with feedback in an order that is less likely to cause confusion. Different conditions (e.g., device status, equipment condition, or physiologic condition) are prioritized based on an analysis of severity of the condition and timeliness of user action needed. The prioritization scheme defines what alert, if any, is presented to the user by the WCD system as a result of various conditions. Generally stated, an alert for the highest priority condition currently detected is presented to the user and maintained until that condition either changes or becomes surpassed in the prioritization scheme.Type: ApplicationFiled: May 6, 2022Publication date: August 18, 2022Applicant: West Affum Holdings Corp.Inventors: Zoie R.

Publication number: 20220257959Abstract: Disclosed is a wearable medical device, such as a Wearable Cardioverter Defibrillator, which includes one or more sensors and a processor coupled to the one or more sensors. The processor is configured to record patient-specific information derived from signals output by the one or more sensors while the wearable medical device is being worn and to execute an algorithm to analyze the recorded information, the algorithm being based on data collected from multiple different persons. The processor is further configured to perform an artificial intelligence analysis of the recorded information, to update the algorithm with update information derived from the artificial intelligence analysis of the derived information, and to use the updated algorithm to analyze subsequent signals output by the one or more sensors while the wearable medical is being worn. The disclosed techniques result in a more patient-specific approach, which results in fewer false alarms.Type: ApplicationFiled: February 10, 2022Publication date: August 18, 2022Applicant: West Affum Holdings Corp.Inventors: Joseph L.
