AED
Using an AED
Different types of AEDs are available, but all are
similar to operate and use visual displays, voice
prompts or both to guide the responder. If your place
of employment has an AED on site, know where it is
located, how to operate it and how to maintain it (Box
3-3). Also take note of the location of AEDs in public
places that you frequent, such as shopping centers,
airports, recreation centers and sports arenas.
When a person is in cardiac arrest, use an AED as soon
as possible. Skill Sheet 3-4 describes how to use an
AED step by step. Environmental and person-specific
considerations for safe and effective AED use are given
in Box 3-4.
what happens the breaths do not make the chest rise.
Never give more than 2 rescue breaths per set. If
the first rescue breath does not cause the chest
to rise, retilt the head to ensure that the airway
is properly opened and ensure that the person’s
nose and mouth are properly sealed before giving
the second rescue breath. If the second breath
does not make the chest rise, an object may be
blocking the person’s airway. Give CPR with one
modification: after each set of compressions and
before giving rescue breaths, open the mouth, look
for an object in the person’s mouth, and if you see it,
remove it.
while Giving CPR
If you check a person and find that he or she is unresponsive and not breathing or only gasping, begin
CPR immediately, starting with chest compressions. Proper technique is important. Skill Sheets 3-1, 3-2
and 3-3 describe step by step how to give CPR to an adult, child and infant, respectively. Table 3-1
summarizes the key differences in giving CPR to an adult, child or infant.
what do you do if you think a person has gone into cardiac arrest?
Have someone call 9-1-1 or the designated emergency number immediately.
Begin CPR immediately.
Use an AED as soon as possible.
what is a heart attack
A heart attack occurs when blood flow to part of the
heart muscle is blocked (e.g., as a result of coronary artery
Using an AED on an Adult
To use an AED, first turn the device on. Remove or cut away
clothing and undergarments to expose the person’s chest. If
the person’s chest is wet, dry it using a towel or gauze pad.
Dry skin helps the AED pads to stick properly. Do not use an
alcohol wipe to dry the skin because alcohol is flammable.
Next, apply the AED pads. Peel the backing off the pads as
directed, one at a time, to expose the adhesive. Place one
pad on the upper right side of the person’s chest and the
other pad on the lower left side of the person’s chest below
the armpit, pressing firmly to adhere (Figure 3-7). Plug the
connector cable into the AED (if necessary) and follow the
device’s directions. Most AEDs will begin to analyze the heart
rhythm automatically, but some may require you to push an
“analyze” button to start this process. No one should touch
the person while the AED is analyzing the heart rhythm
because this could result in a faulty reading. Next, the AED
what do you do if the person vomits or there is fluid in the mouth.
Roll the person onto his or her side and clear the
mouth of fluid using a gloved finger or a piece of
gauze. Then roll the person onto his or her back and
resume giving care.
Giving CPR to an Adult
First, make sure the person is lying face-up on a firm, flat
surface. For example, if the person is on a soft surface
like a sofa or bed, quickly move him or her to the floor
before you begin. Kneel beside the person.
Q Position your hands. Place the heel of one hand
in the center of the person’s chest on the person’s
breastbone (sternum). If you feel the notch at the
end of the breastbone, move your hand slightly
toward the person’s head. Place your other hand
on top of your first hand and interlace your fingers
or hold them up so that your fingers are not on the
person’s chest. If you have arthritis in your hands,
you can grasp the wrist of the hand positioned on
the chest with your other hand instead. The person’s
clothing should not interfere with finding the
proper hand position or your ability to give effective
compressions. If it does, loosen or remove enough
clothing to allow deep compressions in the center of
the person’s chest.
Q Give a set of 30 compressions. Position your
body so that your shoulders are directly over your
hands. This will let you push on the chest using a
straight up-and-down motion, which moves the most
blood with each push and is also less tiring. Keeping
what is CPR
CPR, or cardiopulmonary resuscitation, is a skill that
is used when a person is in cardiac arrest to keep
oxygenated blood moving to the brain and other vital
organs
Signs and Symptoms
of a Heart Attack
Chest pain,Discomfort or pain that spreads to one or both arms,Dizziness or light-headedness,
Trouble breathing, including noisy breathing, shortness of breath or
breathing that is faster than normal,Nausea or vomiting,
Pale, ashen (gray) or slightly bluish skin, especially around the face
and fingers,Sweating,A feeling of anxiety or impending doom,Extreme fatigue,Unresponsiveness
Using an AED on a Child or Infant
The procedure for using an AED on a child or infant is the same as the procedure for using an AED on an
adult. Some AEDs come with pediatric AED pads that are smaller and designed specifically to analyze a
child’s heart rhythm and deliver a lower level of energy. These pads should be used on children up to 8 years
of age or weighing less than 55 pounds. Other AEDs have a key or switch that configures the AED for use on
a child up to 8 years of age or weighing less than 55 pounds. If pediatric AED pads are not available or the
what do you do if you are unable to form a tight seal over the
person’s mouth
Use mouth-to-nose breathing instead. With the
person’s head tilted back, close the person’s mouth
by pushing on the person’s chin. Make a complete
seal over the person’s nose with your mouth and
blow in for 1 second to make the chest rise.

How many breaths and compression's do you use for cpr?
30 compressions and 2 breaths
what should you do if you see someone having a heart attack?
call 911, have the person sit and relax, loosen tight clothing, keep the person comfortable and monitor them
AED Maintenance
AEDs require minimal maintenance, but it is
important to check them regularly according
to the manufacturer’s instructions or your
employer’s policy to ensure that they are in
good working order and ready for use whenever
they are needed.
The person has a tracheostomy or “stoma,” a
surgically created opening in the front of the neck
that opens into the trachea (windpipe) to form an
alternate route for breathing when the upper airway
is blocked or damaged.
Use mouth-to-stoma breathing instead. Expose the
person’s neck down to the breastbone and remove
anything covering the stoma (e.g., a filter or stoma
cover). Wipe away any secretions from the stoma.
Make a complete seal over the person’s stoma or
tracheostomy tube with your mouth and blow in for
1 second to make the chest rise.

what is Cardiac Arrest?
Cardiac arrest, occurs when the heart
stops beating or beats too ineffectively to circulate blood to
the brain and other vital organs.

right side of the chest and the other on the
lower left side of the chest, below the armpit.

abnormal heart rhythms
in particular, ventricular
fibrillation (V-fib) and
ventricular tachycardia (V-tach), can lead to sudden cardiac
arrest.
Signs and Symptoms of Cardiac Arrest
When a person experiences cardiac
arrest, you may see the person suddenly
collapse. When you check the person,
you will find that the person is not
responsive and not breathing, or only
gasping. (In an unresponsive person,
isolated or infrequent gasping in the
absence of normal breathing may be
agonal breaths, which can occur even
after the heart has stopped beating.
Agonal breaths are not breathing and
are a sign of cardiac arrest.) The person
has no heartbeat.
