RESUSCITATION
INTRODUCTION
According to recent statistics sudden cardiac arrest
is rapidly becoming the leading cause of death in
America. Once the heart ceases to function, a
healthy human brain may survive without oxygen for
up to 4 minutes without suffering any permanent
damage. Unfortunately, a typical EMS response may
take 6, 8 or even 10 minutes.
It is during those critical minutes that CPR (Cardio
Pulmonary Resuscitation) can provide oxygenated
blood to the victim's brain and the heart, dramatically
increasing his chance of survival. And if properly
instructed, almost anyone can learn and perform
CPR.
CPRDEFINITION :
“It is an emergency medical
procedure for a victim of cardiac
arrest or , in some circumstances,
respiratory arrest.”
REVIEW OF ANATOMYAND PHYSIOLOGY
HEART
HODS - November 2006 7
HEART
HODS - November 2006 8
HEART Hollow, muscular organ
300 grams (size of a fist)
4 chambers
Found in chest between lungs
Surrounded by membrane called
pericardium
Pericardial space is fluid-filled to
nourish and protect the heart.
HODS - November 2006 9
HEART ANATOMY
The heart is a complex
muscular pump that
maintains blood
pressure and flow
through the lungs and
the rest of the body.
The heart pumps about
100,000 times and
moves 7200 liters (1900
gallons) of blood every
day.
HODS - November 2006 10
HEART ANATOMY The heart has four
chambers.
Two atria act as
collecting reservoirs.
Two ventricles act as pumps.
The heart has four valves for:
Pumping action of the heart.
Maintaining unidirectional blood flow.
HODS - November 2006 11
Functions of the Heart
Generates blood pressure
Routes blood
Heart separates pulmonary and systemic circulation
Ensures one-way blood flow
Heart valves ensure one-way flow
HODS - November 2006 12
Functions of the Heart
Regulates blood supply
Changes in contraction rate and force match blood delivery to changing metabolic needs
The Heart: Conduction System
The heart pumps blood through the body
This is accomplished by contraction and relaxation of the cardiac muscle tissue in the myocardium layer.
Intercalated discs allow impulses to travel rapidly between adjacent cells so they function as one rather than individual cells
Cardiac Muscle Tissue

Conduction System Continued….
Cardiac conduction system: The
electrical conduction system controls
the heart rate
This system creates the electrical
impulses and sends them throughout
the heart. These impulses make the
heart contract and pump blood.
Components of the Conduction System Sinoatrial node (part I):
Located in back wall of the right atrium near the
entrance of vena cava
Initiates impulses 70-80 times per minute without
any nerve stimulation from brain
Establishes basic rhythm of the heartbeat
Called the pacemaker of the heart
Impulses move through atria causing the two atria
to contract.
At the same time, impulses reach the second part of
the conduction system
Components of the Conduction SyStem Continued ….
Atrioventricular node (part II):
Located in the bottom of the right atrium
near the septum
Cells in the AV node conduct impulses more
slowly, so there is a delay as impulses travel
through the node
This allows time for atria to finish contraction
before ventricles begin contracting
Septum
Atrioventricular Bundle “Bundle of His”
From the AV node, impulses travel through to the right and left bundle branches
These branches extend to the right and left sides of the septum and bottom of the heart.
Atrioventricular Bundle Continued….
These branch a lot to form
the Purkinje fibers that
transmit the impulses to
the myocardium (muscle
tissue)
The bundle of His, bundle
branches and Purkinje
fibers transmit quickly and
cause both ventricles to
contract at the same time
Like a “phone tree”
Atrioventricular Bundle Continued….
As the ventricles contract, blood is
forced out through the semilunar valves
into the pulmonary trunk and the aorta.
After the ventricles complete their
contraction phase, they relax and the SA
node initiates another impulse to start
another cardiac cycle.
1 - Sinoatrial node (SA node)
2 - Atrioventricular node (AV node)
3 – Bundle of His
4 - Right & Left Bundle Branches
which lead to Purkinje Fibers

SHOUT FOR HELP
CHECK FOR CAROTID
PULSERESCUE BREATH FOR THEM:
- 1 breath every 5 to 6 seconds
for about 10-
12 per minute (each breath should
be
delivered over 1 second making
the chest
rise)
- Recheck pulse every 2 minutes
IF THE VICTIM DOES NOT HAVE CIRCULATION (NO PULSE)
Start chest compressions, at the center of the chest at
the nipple line with the heal of one hand on top of the
other, at a ratio of:
- 30 compressions to 2 ventilation at a rate of
100 per minute and a depth of 1 ½” to 2”
- Reassess after 5 cycles of 30 compressions to 2
breaths, after 2 minutes
• Place the heel of one hand
in the centre of the chest
• Place other hand on top
• Interlock fingers
• Compress the chest
– Rate at least 100 / min
– Depth at least 2 inches
– Equal compression :
relaxation
• When possible change CPR
operator every 2 min
CHEST COMPRESSIONS
OPEN AIRWAY
HEAD TILT & CHIN LIFT
JAW THRUST
HEAD-TILT CHIN-LIFT
The head-tilt chin-lift is the
primary maneuver used in
any patient in whom cervical
spine injury is not a
concern. The simplest way
of ensuring an open airway
in an unconscious patient is
to use a head tilt chin lift
technique, thereby lifting the
tongue from the back of the
throat. This is taught on
most first aid courses as the
standard way of clearing an
airway.
JAW THRUST
The jaw-thrust maneuver is an effective airway technique,
particularly in the patient in whom cervical spine injury is a concern.
The jaw thrust is a technique used on patients with a
suspected spinal injury and is used on a supine patient. The
practitioner uses their thumbs to physically push the posterior (back)
aspects of the mandible upwards - only possible on a patient with
a GCS < 8 (although patients with a GCS higher than this should also
be maintaining their own patent airway). When the mandible is
displaced forward, it pulls the tongue forward and prevents it from
occluding (blocking) the entrance to the trachea, helping to ensure a
patent (secure) airway.
FOREIGN-BODY AIRWAY
OBSTRUCTION (FBAO)
Approximately 16 000 adults and children receive treatment for FBAO in the UK yearly
SIGNS MILD obstruction SEVERE obstruction
“Are you choking?” “YES” Unable to speak,

DEFIBRILLATION
AUTOMATED
EXTERNAL
DEFIBRILLATOR
(AED)
Some AEDs will
automatically switch
themselves on when
the lid is opened
Automatic External
Defibrillator
- Why we use the AED?
- How to use the AED?
- Indications for the AED?
- Contraindications to AED?
Objectives for this
subject
Defibrillation is
the application
of electrical
shock to help
restore the
heart’s regular
rhythm
Defibrillator is the device
used to deliver that shock
and it can be manual or
automatic.
Early defibrillation is the single
most important factor in
determining survival from cardiac
arrest.
AED
Most common initial rhythms patients go into as they enter into cardiac arrest are:
“2 Shockable Rhythms”
V-Tach and V-Fib
Ventricular Tachycardia:Fast heart rhythm which does not
allow the heart to fill properly and
cardiac output is compromised and
reduced.
Ventricular Fibrillation:disorganized series of electrical
discharges in the ventricles. Where
the ventricles “quiver”.Stops Cardiac
output and hearts pumping ability.
AED’s that are available are
automatic and semi-
automatic.
Automatic: where machine
does all of the work.
Semi Automatic: where
machine tells you when to
push button to deliver shock.
Apply AED
as soon as
you
determine
that your
patient is not
breathing
and does not
have a pulse.
Always making sure that
CPR is still in progress while
you are setting up the AED.
If by yourself, apply the AED.
Ensure before putting pads on chest, it is clear of all patches, paste or pacemakers. Don’t cover something up with pad.
ATTACH PADS TO CASUALTY’S
BARE CHEST
Now attach the
adhesive pads to
the cables
remembering-
White is negative,
anterior chest wall.
Red is positive ,
left anterior axillary
line.
“Red on Ribs! White on right!”
Now turn on
machine and
wait for AED to
analyze the
patients
rhythm. Making
sure that CPR
has been
stopped for
machine to
detect rhythm.
When machine advises a
shock is indicated,
”CLEAR”
your patient.
Ensuring that no one is
touching patient or stretcher.
When the AED delivers a shock
it will go back and reanalyze the
rhythm.
If another shock is appropriate
“Clear Patient”
and
deliver the shock.
Sets of 3 shocks are called
stacked shocks and they are
done without any pauses to
check patients pulse or
administer CPR
IF VICTIM STARTS TO BREATHE
NORMALLY PLACE IN RECOVERY
POSITION
If “No shock” is indicated:
-Check breathing
give appropriate oxygen therapy.
-Check pulse, if no pulse!
Start CPR for
1 minute and then have the AED
reassess.
Safety should always be
maintained by the provider:
-Not using near or around water
-Ensuring all med patches and pastes are
off the patient.
-Making sure that everyone is clear of the
patient when the shock is delivered.
Indications for AED
* Unresponsive
* Apneic
* Pulseless patients.
Adult Patients
> 8 years old
> 55 lbs.
Unresponsive,pulseless and
apneic.
Contraindications:
Infants and children
< 8 years old
< 55 lbs.
Contraindications:
!! Hypothermia !!
(Contact medical control)
Contraindications:
Rigor / Livor Mortis
No Code /DNR
The AED can’t properly
analyze patient in
moving ambulance.
It is recommended that you
stop the medic and let AED
do it’s job.
CONTINUE RESUSCITATION
UNTIL
Qualified help arrives and takes over
The victim starts breathing normally
Rescuer becomes exhausted
TERMINATION OF BLS
