Running a Car Seat Assessment Record
In the NER group you can run a Car Seat Assessment Record (CAR). This is a special period of event
surveillance using the current setup of the NER group.
To start a CAR period:
1 Select the Start CAR pop-up key or SmartKey.
2 Select the required time period for the assessment.
3 Select Confirm to start the CAR.
If the NER group was not active it will be activated automatically.
During the CAR period an SpO
2
histogram is also generated with 1 second samples. For general
information about the presentation of data in a histogram, see “Viewing Histogram Trends” on
page 272. The CAR SpO
2
histogram is unique: it can only be accessed from the events function. It is
generated from the beginning of the CAR period (contrary to the non-SpO
2
histograms which are
generated from trended data retrospectively at the end of a time period). Settings are fixed for this
histogram and cannot be changed when viewing it.
The Events Database
The maximum number of events that can be stored in the event database depends on the database
configuration and the level of event surveillance used. The event database is set up in the monitor's
Configuration Mode. Events are stored in the monitor's event database for the configured lifetime,
either 8 hours or 24 hours. Deleted events cannot be retrieved. Events are automatically deleted when:
• their configured lifetime is over
• the storage capacity of the database is exceeded (storing a further event deletes the oldest event in
the memory)
• a patient is discharged.
As the event database is cleared when you discharge a patient, you should ensure that you have
documented any events you require for the patient records before you confirm the discharge.
Viewing Events
• To see a summary of all the events in every group in the event database, use the Event Summary
window.
• To review all the events in a particular event group, use the
Event Review window.
• To review individual event episodes in detail, use the
Event Episode window.
To start viewing events, either:
•in the
Main Setup menu, select Event Surveill. and then select the event view you require from the
list, or
• select the
Event Surveill SmartKey
and then select the event view you require from the list.
