Event Groups
The event group
• monitors the patient's signals to detect event triggers
• defines which waveforms are recorded in the event data.
In basic event surveillance only one event group can be active at a time, with Advanced Event
Surveillance all six groups can be active simultaneously. Active event groups monitor for event triggers.
Event groups are defined in Configuration Mode. In monitoring mode the groups can be adapted to
current conditions, for example episode types and threshold levels can be changed.
Event Episodes
When an event occurs, information for a predefined duration is stored. This is the event episode. It
includes information from a defined period before the trigger, called the event pre-time. The episode
time after the event is called the event post-time. If a further event occurs during the event post-time it
changes a single event to a combined event (combi-event).
Manually-triggered event episodes document patient information from the time leading up to the event
trigger; they do not have a post-time.
The episode type defines the level of detail captured in an event episode. The higher the data
resolution, the shorter the period that the monitor can store in its memory. High-resolution data is
