Abstract

A system and method provide information in response to at least one current event related to a treatment performed by a dialysis system. A first number is displayed at a treatment display in communication with the dialysis system. The first number corresponds to a set of current notifications. Each current notification is generated in response to at least one current event related to the treatment. A new event is detected that is related to the treatment. The first number is increased to a second number in response to detecting the new event. The second number corresponds to a new notification generated in response to the new event and corresponds to the set of current notifications. A highest priority event is determined between the new event and the at least one current event. The treatment display displays at least one notification corresponding to the highest priority event.
