Abstract

Systems and methods can support presenting patient alarms to clinical care users. An alarm management system can maintain a mapping of patients to users as well as user context information. The alarm management system can receive alarm indications from medical devices associated with the patients along with alarm context information associated with the alarm indication. The alarm management system can determine a target user among the users according to evaluating the mapping of patients to users, the user context information, and the alarm context information. The alarm management system can determine a notification modality according to evaluating the alarm indication, the target user, a portion of the user context information associated with the target user, and the alarm context information. The alarm management system can transmit the alarm indication, the alarm context information, and the notification modality to a mobile device for presentation to the target user.
