1: Introduction
About the LifeVest system
The LifeVest device continuously monitors your heart. If it detects a life
threatening rhythm that is too fast, the device delivers treatment to restore
normal rhythm. If you are conscious, you can prevent a treatment by using the
response buttons when the device alerts you that a treatment is coming.
About this manual

Safety information
This information helps you safely operate the LifeVest device. Read and
understand these warnings, cautions, and symbols before using the device.
Terms used
WARNING: Warns you of possible injury or death that can be caused by
misuse of the device. This includes device failure that could lead to you being not
protected by the device.
CAUTION: Advises you of a possible problem with the device. Such
problems include damage to the device or other property, or minor injury.
Shock hazard
Always wear the LifeVest device and make sure the electrode belt and
battery are properly connected to the monitor. The device cannot detect an
abnormal rhythm or deliver a treatment if not worn and properly connected.
Do not let another person wear your LifeVest device. Because the device has
been programmed to recognize your specific heart rhythm pattern, if it detects
an unfamiliar heart rhythm, it may shock that person.
Do not attempt to open the monitor, battery, charger, or electrode belt. This
may expose you to high voltage and damage the system.
Rescue defibrillation
If you should require conventional defibrillation, a warning label on the
garment informs medical personnel to unfasten and lay open the garment,
thus removing the front therapy pad from your chest. If the garment remains
fastened and connected, the LifeVest device may interfere with the
defibrillation, and the conventional defibrillator may damage the device.
To help ensure proper operation
Page 1-2
Use the LifeVest device only after you understand all training and
instructions.
Do not put anything other than the monitor into the holster. The extra weight
may pull the electrode belt from the body.
Keep the device out of the reach of children. The device may be damaged by
improper handling.
Do not kink the cables. Kinking the cables may damage them and cause the
system to malfunction.
1-800-543-3267
Introduction
Do not drop the device. If you do drop one of the device components, inform
ZOLL Lifecor immediately.
Do not put foreign objects, such as fingers, paper clips, or hair pins into any
connectors or openings.
Protect the device from moisture and extreme sunlight when wearing it
outdoors. To protect the device, always wear clothing over the garment and
keep the monitor and battery in the holster.
Do not put the monitor, electrode belt, battery, or charger in or near water. Do
not bathe or shower while wearing the LifeVest device. Also, before washing
the garment and holster, be sure to remove the electrode belt and the
monitor.
Do not allow food or liquid to splash or drip on the LifeVest device.
Do not expose the device to direct sunlight, excessive heat, or excessive cold
for prolonged periods of time.
Use only the cables, batteries, and accessories specified in this manual. If
you use any other items, the system may not operate correctly.
Operate the system within the range of 0°C to 50°C (32°F to 122°F), up to
95% relative humidity (non-condensing), and up to 10,000 feet in altitude.
Risk of fire
Use appropriate caution in an oxygen-rich environment. As with any
defibrillator, there is a risk of sparking during defibrillation.
Gel release
The therapy pads should not release gel unless a treatment is about to be
given. Gel seepage at any other time indicates a damaged electrode belt. If
this occurs, call your device provider immediately.
If the therapy pad gel gets into your eyes, flush your eyes immediately with
water and contact your physician. Your eyes may become irritated from the
gel.
The LifeVest device has not been tested or approved for use in aircraft.

Electromagnetic interference
Many common devices, including motors and electronic equipment, may produce
electromagnetic interference, also known as EMI, that can affect the operation of
the LifeVest device. The LifeVest device has been tested with a number of
common sources of such interference, including cellular telephones, airport
security systems, and anti-theft detection systems. This testing, along with
clinical trial testing, has demonstrated that in everyday use the LifeVest device is
not normally affected by commonly encountered electromagnetic interference.
Anti-theft detection systems, also known as electronic article surveillance
systems, are often used in department stores and libraries to prevent theft by
electronically sensing a special tag on a piece of merchandise when the tag
passes through a detector gate. In the USA, these detector gates are commonly
located near the doorways. In Europe, the detector gates may be positioned near
the checkout areas.
To prevent possible interference with the LifeVest device, follow these simple
guidelines when passing through airport security gates or anti-theft detection
gates:
Walk through the gate at a normal pace.
Avoid lingering near or leaning on the gate.
In some occupational and hospital environments, unusually high levels of
electromagnetic interference may be encountered. Examples of possible sources
of such interference include: communication equipment such as microwave
transmitters, arc welding equipment, high voltage transmission lines,
electrocautery systems, and electronic muscle stimulators. These environments
should be avoided while wearing the LifeVest device.
In the unlikely event that electromagnetic interference causes you to receive
arrhythmia alarms, hold the response buttons to prevent being shocked and
move away from the source of the interference. The LifeVest device should
return to normal monitoring mode in approximately 5 seconds.
Page 1-4
1-800-543-3267
Introduction
Wireless interference
The LifeVest can be susceptible to or cause wireless interference. Follow these
instructions:
Cell phone use – When using a cell phone, keep it at least 8 inches away
from the sensing electrodes (the round ones) on the electrode belt. If you
experience noise alarms while using a cell phone, move the cell phone away
from the electrode belt or stop using the cell phone.
Charger use – The charger contains a cell phone for data transmissions.
Keep the charger at least 8 inches away from your body to prevent
interference. If you experience interference when near the charger, move
away from the charger. If you take the charger to a hospital, be sure that the
use of cell phones is permitted. If not, do not use the charger while in the
hospital. If you need to transmit data, use the wired modem connection.
General precaution – If you experience any interference with the LifeVest
when in the presence of any other wireless device, move away from the
device or stop using it. If you continue to have problems, call ZOLL Lifecor at
1-800-543-3267.

What family members need to know
Who this information is for
This information is for the family and friends of the person wearing the LifeVest
device.
What you need to know
Since your family member or friend may be wearing the LifeVest device for a
period of time, you may want to understand the daily routine involving the device,
as well as warnings and cautions directed to the patient. In that case you should
probably read this entire manual.
Information for family members
Anyone associated with the patient should be aware of the following information:
Don’t hold the response buttons for the patient. Only the patient should
press the response buttons. The patient’s ability to press the response
buttons lets the device know whether or not the patient is still conscious and
is critical in deciding when to give the patient a shock.
WARNING: If anyone other than the patient holds the response buttons,
needed therapy may not be delivered, possibly resulting in serious injury or
death.
Page 3-20
Don’t touch the patient when a treatment is about to occur. If anyone
touches the patient when the patient receives a treatment, the person
touching the patient will be shocked.
Don’t remove the battery, don’t disconnect the electrode belt from the
monitor, and don’t loosen the garment unless you are prepared to do
CPR (cardiopulmonary resuscitation) on the patient.
Don’t let anyone else wear the LifeVest device. If someone other than the
patient wears the device, it will not recognize the unfamiliar heart rhythm and
may shock that person.
If the LifeVest shock does not revive the patient and the patient is
unconscious, call 911 (or your emergency medical service) and then start
CPR.
A label on the front of the garment reminds medical personnel to open the
garment before giving the patient conventional external defibrillation.
Keep the LifeVest device out of the reach of children.
1-800-543-3267

5: Responding to alerts
Types of alerts
How you respond to an alert depends on the type of alert you get. There are
three types of alerts:
vibration
siren
gong
Vibration
If you get a vibration in the back of the electrode belt, you are
being warned that you’re about to get a siren alert. You will also
get a short vibration alert every time you change the battery.
Press the response buttons to stop this alert.
Follow the same instructions as for the siren alert on page 5-2.
Siren
The siren is a high-pitched two-tone alarm that means an
abnormal rhythm has been detected.
Press the response buttons to stop this alert. If you don’t
respond to this alert, you will probably receive a treatment
within the next minute.
Follow the instructions on page 5-2.
Gong
The gong is a low-pitched “gong” sound that repeats about
once a second.
This type of alert is accompanied by a message stating a
problem that needs your attention. Read the message to see
what action needs to be taken. For specific help, press the help
button on the screen.

Voice prompts also alert bystanders to call an
ambulance after you have been given a treatment.
WARNINGS:
Page 5-2
If you fail to press the response buttons when you are awake, you may
receive a treatment, which will be painful. That is why you need to press the
response buttons if you get the siren alert.
If you receive a treatment while your heart is beating normally, the treatment
may cause an abnormal rhythm to occur. There is a small possibility that the
abnormal heart rhythm may not be detected and death may result.

person press them for you. If anyone other than the patient presses the
response buttons, needed therapy may not be delivered, possibly resulting in
serious injury or death.

Device disabled message
If the LifeVest detects an untreatable condition called
asystole, where your heart slows and stops, it will display
this message to alert bystanders.
Under rare circumstances, it may display this message
when your heart has not stopped.
If you are conscious and you feel OK and you get this
message, follow the instructions below.
If you get this message and you’re conscious
The problem may be with the signal from the ECG electrodes. Follow this
procedure to correct the problem.
Remove and reinstall the battery.
If the message returns, check your electrode belt and garment. Make sure:
Page 5-18
All ECG electrodes are touching your skin.
Nothing is between the ECG electrodes and your skin, such as clothing or
one of the cables.
Garment and belt fit snugly, with the electrodes pressing against your
skin.
If you continue to get this message even though you remain conscious, call
ZOLL Lifecor.
