Data Storage; Data And Audio Recording - ZOLL AED 3 Administrator's Manual

Data Storage

The ZOLL AED 3 defibrillator stores the following patient clinical archive and
device history data:
Clinical Archive Data (.crd)
(Clinical Event File)
• Elapsed time (since power on)
• Continuous ECG Data
• Number of patient shocks
• Selected energy
• Patient impedance
• Audio prompts
• Audio recording (if applicable)
• Power on (date and time)
• Indication of defibrillation pad
attachment
• Results of ECG analysis
• CPR data
• Errors
The ZOLL AED 3 defibrillator generates device history data when it performs a
self-test during power up or at a scheduled time during sleep state. When the
AED detects system issues it saves these issues in device log files.

Data and Audio Recording

The ZOLL AED 3 BLS model has an audio recording option that can be configured
on or off. If the audio recording option is on, the ZOLL AED 3 BLS model can
record and store 60 minutes of continuous audio, ECG, and clinical event data.
If the audio recording option is off, the ZOLL AED 3 BLS model can record and
store 120 minutes of clinical event data and ECG data. The recorded audio data
is synchronized to the clinical event data. The audio recording starts when
defibrillation pads are attached and the AED completes its automatic self tests.
All ZOLL AED 3 models can be configured to store one or two patient cases
containing ECG, audio (BLS model), and clinical event data. When the AED is
configured to store two cases and a clinical event is detected in rescue mode,
the AED deletes the oldest of the two previously stored cases from memory
before recording data for the current rescue. If the AED is configured to store
one case, it deletes the stored case from memory before recording data for the
current rescue. Deleting of old ECG, audio, and event data occurs 15 seconds
after the defibrillation pads are properly connected to the patient. If the
ZOLL AED 3 defibrillator is started in AED Management Mode, the recorded data
of the last rescue is retained and may be transferred using a wireless connection
or USB flash drive.
