Data Management
4 Data Management
The AED stores all data for the Current Patient (B). However, the AED only retains the Event Log and
CODE SUMMARY data for the Previous Patient (A).
Information Stored When Creating a New Patient Record
When the AED creates a new patient record, the following occurs:
• The AED stores all data for the newest patient record, Patient C (refer to Figure 4-3). Patient C is now
the Current Patient.
• The AED deletes the ECG and audio recording data for Patient B. The AED retains only the Event
Log and CODE SUMMARY data. Patient B is now the Previous Patient.
• The AED deletes all data for the oldest patient record, Patient A.

Conditions for Creating a New Patient Record
To begin a new patient record, the following conditions must occur:
• The AED must be turned off for at least 60 seconds, then turned on.
• Electrodes must be connected to the patient.
You can turn off the AED briefly without affecting the Current Patient. For example, you can change the
battery. If you restore power in less than 60 seconds, the AED resumes storing data for the Current
Patient.
If you do not connect electrodes to a patient or a simulator, you can turn on the AED and not affect the
Current Patient. For example, you can turn on the AED to test it with the external test load or to transfer
data. As long as you do not connect the electrodes to a new patient or an ECG simulator, the AED does
not create a new patient record.
As soon as you turn on the AED, the AED begins storing data for a new patient record. However, if you
do not connect electrodes to a patient within 3 minutes, the AED stops storing data.
• If you then connect electrodes, the AED resumes storing data and creates a new Current Patient.
• If, however, you turn off the AED without ever connecting the electrodes, the AED does
not
create a
new Current Patient. The AED will delete the initial 3 minutes of data, and all previously stored data
will remain unchanged. This prevents erasing data each time you turn on the AED to transfer data or
perform maintenance.
Test Log
The LIFEPAK 500 AED also stores a Test Log, a list of the 30 most recent auto-tests and manual tests.
The Test Log lists the test results and any fault codes detected. The Test Log is printed automatically
when data is sent to a printer. As an option, the Test Log may be printed from a computer.
