IHE Patient Care Device Technical Framework Supplement – Alarm CommunicationManagement (ACM)______________________________________________________________________________430Each actor is identified below. Actor identity is implicitly identified in the alarm (for example,through MSH-21 Message Profile, identifying the message as PCD-04 by OID, which is sent byan ACM AR actor, which is identified in MSH-3 Sending Application).The functional units comprising an actor may be provided by one or more vendors in one ormore systems. Reducing the total number of systems is preferred, but is not required.Data flow of individual use model messaging communication indicates the command responsesequences and directions.435440445450455Alarm Reporter (AR) ActorThis actor originates the alarm.The semantics and data types used to represent alarm type, alarm priority, alarm inactivationstate and escalation and de-escalation of priority in the messages of this actor are based on IEC60601-1-8 definitions.A single source can produce multiple, possibly concurrent, alarms.A single Report Alarm transaction can contain at most a single alarm.This profile specifies the required data and data types produced by this actor.This profile specifies communication of the data produced by this actor.This actor may optionally cancel an outstanding alarm condition.This may optionally indicate cancellation of any related escalation.An outstanding alarm condition may be optionally escalated via follow-on alarm.This actor may aggregate and adapt alarms from multiple sources as needed to make theminteroperable with the AM actor. It does not need to be the original source of the alarm data.In large alarm source populations, an aggregation system may be useful for concentration andpossible alarm coordination (smart alarming).Alarm Manager (AM) ActorThis actor receives alarms from the AR, manages them, and dispatches them to the AC actor.The semantics and data types used to represent alarm type, alarm priority, alarm inactivationstate and escalation and de-escalation of priority in the messages of this actor are based on IEC60601-1-8 definitions.This profile specifies the required data and data types produced by this actor in communicationwith the AC and AR actors.If the following is performed, it is likely performed within the AM.Alarm formatting for dissemination__________________________________________________________________________17Rev. 1.3– 2012-08-16Copyright © 2012: IHE International, Inc.
