Preface

FEATURES OF THE LIFEPAK 500 AUTOMATED EXTERNAL DEFIBRILLATOR

The optional and configurable features of the LIFEPAK 500 AED are designed to meet a variety of

protocol needs. Authorized operators of this AED should always use the AED in accordance with local

protocols.

Defibrillation Waveform

The LIFEPAK 500 AED is available with one of two defibrillation waveforms: monophasic or biphasic.

For a description of each defibrillation waveform, refer to page 5-14 and page 5-17. The LIFEPAK 500

AED control and display functions are the same for either defibrillation waveform.

Defibrillation Electrodes

The LIFEPAK 500 AED uses disposable QUIK-COMBO

™

pacing/defibrillation/ECG electrodes, with or

without the REDI-PAK

™

preconnect system, and FAST-PATCH

disposable defibrillation/ECG

electrodes. The use of these electrodes allows rapid transfer of care to other devices that also use the

same type of Medtronic Physio-Control electrodes.

Infant/Child Reduced Energy Defibrillation Electrodes can be used only with a biphasic LIFEPAK 500

AED that has been modified specifically to accept these electrodes. (Refer to Item 4, Cable Connector

on page 2-3.) Infant/Child Reduced Energy Defibrillation Electrodes are not transferable to manual

defibrillator/monitors.

Automated Operation

The operator controls AED operation with two or three top-panel buttons (ON/OFF, ANALYZE [optional],

and

SHOCK). For LIFEPAK 500 AEDs that do not have an ANALYZE button, the AED operates in AUTO

ANALYZE 2

mode (see page 2-9).

The AED guides the operator through operating procedures with a combination of:

• Voice prompts

• Tones

• Flashing LEDs

• Screen messages

The screen messages appear on a two-line liquid crystal display (LCD). Other LCD information

includes:

• Real-time clock

• Cumulative shock counter

• Status and service messages

• CPR countdown timer

Continuous Monitoring

The LIFEPAK 500 AED operates in two modes: ECG analysis and Continuous Patient Surveillance

System (CPSS). During analysis, the AED indicates if it detects a shockable or nonshockable rhythm.

The CPSS, which is active when the AED is not performing an analysis, automatically monitors for a

potentially shockable rhythm.

Motion Detection

The LIFEPAK 500 AED includes a patented system that detects motion. When motion that could distort

the ECG rhythm occurs, the ECG data is automatically excluded from analysis by the motion detection

system.
