2. THE HUMAN HEART
 Expands & Contracts
 Pumps blood
 Beats for a lifetime

3. HOW HEART WORKS
Generates a pumping

Blood pressure…

blood pressure…

4. HOW THE HEART WORKS
Sends oxygen carrying
red blood cells to the brain

5. The Problem?
Premature Death !!

6. Causes of Death….
† Sudden Cardiac Arrest
† Stroke
† Lung Cancer
† Breast Cancer
† Auto Accidents
† HIV/ AIDS
† Murder

7. With the HELP of Medical Science……
We can MAKE a
DIFFERENCE !!!

8. LIFE OR DEATH!! IS NOW A MATTER OF
TIME!!!!
SITUATION…. © Unconscious
© Unresponsive
© No breathing
© Looks terribly
sick & discolored

9. CARDIAC ARREST: Problem #1
Cardiac Arrest ( Asystole)

10. Cardiac Arrest Problem #2
• Ventricular Fibrillation
• Cardiac arrest leading to VF

11. SUDDEN DEATH HAPPENED!

12. Ventricular Fibrillation
An abnormally irregular
heart rhythm caused by
rapid, uncoordinated
contractions of the
ventricles.

13. CHAIN OF SURVIVAL

14. DEFIBRILATION
Is a process in which an electric device sends an electric
shock to the heart to stop an extremely rapid, irregular
heartbeat, and restore the normal heart rhythm.
PURPOSE OF DEFIBRILLATION:
 Is performed to correct life threatening fibrillation of the
heart which could result in cardiac arrest.

17. TYPES OF DEFIBRILLATOR
1. Internal Defibrillator
Electrodes are placed directly to the heart.
Ex: ICD or Pacemaker
2. External Defibrillator
Electrodes are placed directly on the heart.
Ex: AED

19. MECHANISM

20. PADDLE/ PADS PLACEMENT

21. Electrode Pad placement

22. FACTORS AFFECTING SUCCESS
IMPEDANCE Circuit, Paddle size; Electrode
PLACEMENTOF PADDLES 
Over Right upper chest
Apex of the heart
Anterior – Posterior
ENERGY DOSE:
2J/Kg 1st shock-----4J/Kg

25. OPERATION OF AED
1. Water = Water is a good conductor of electricity.
2. Children = > 8years of age or
> 25 kg body wt
3. Transdermal Medications
4. Implanted Pacemakers/ICDs

26. COMMON STEPS TO FOLLOW
Step 1: POWER ON the AED
Step 2: Attach electrode pads
Step 3: Analyze the rhythm
shock indicated
No shock indicated
Step 4: Clear the victim and press the SHOCK button

27. OUTCOME OF THE ATTEMPT
 “Shock Indicated” Message: Recurrent VF
Resume CPR for 60 seconds
If VF continues + 3 shocks + CPR
 “No Shock Indicated” Message
Check pulse if no pulse do CPR
 Signs of Circulation Present
+ Pulse  check breathing
- No breathing  Provide rescue breathing at 10
to 12 / min
+ Breathing position pt to recovery position

28. Care After Successful Defibrillation
• Place the patient in a recovery position, kept
AED attached.
• Continue to monitor the victim.
• Check breathing and signs of circulation
frequently.
RISK IN DEFIBRILLATION
 Skin burn from the defibrillator paddles
 Injury to the heart muscles; Abnormal heart
rhythmn & Blood clots

31. CARDIOVERSION
 Is a Medical Procedure by which an
abnormal heart rate is converted to a normal
rhythm using electricity or drugs. Synchronized
electrical cardioversion uses a therapeutic dose
of electric current to the heart at a specific
moment in the cardiac cycle.

YOU Can
Save A LIFE!!!
