The Infusion Pump Event Communication (IPEC) Profile specifies methods for communicating significant clinical and technical events from a Patient Care Device such as infusion pump to an information system which may present it to a clinical user, acts on it in some way or records it. The information is communicated in a data format similar to that of Device Enterprise Communications (DEC) Profile, but differs in that DEC is mainly used for sampled physiological and technical data at timed, equal intervals, while IPEC is used to communicate significant occurrences which happen at unscheduled times. Infusion Pump Event Communications is also related to Alarm Communications Management (ACM) Profile, except that ACM is designed for physiological alarms and technical alerts to a human actor via portable devices, where IPEC is designed for system-to-system communication for automated recording or tracking occurrences which do not necessarily require urgent attention from a person.
