DEFIBRILATOR PPT.pptx for nursing students
- 2. Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat. They are used to prevent or correct an arrhythmia, an uneven heartbeat that is too slow or too fast. If the heart suddenly stops, defibrillators can also help it beat again.
- 3. PURPOSE: TO CORRECT LIFE THREATENING FIBRILATION OF THE HEART WHICH COULD RESULT FROM CARDIAC ARREST
- 4. ●There are different kinds of defibrillators in use today. ●They include ● manual external defibrillator, ● manual internal defibrillator, ● automated external defibrillator (AED), implantable cardioverter-defibrillator (ICD), ● wearable cardiac defibrillator.
- 6. types of manual external defibrillator, types of manual defibrilator 1.monophasic defirilator{Monophasic AEDs are devices that emit a type of shock. It sends an electrical current in a single direction from an electrode on one side of the chest to an electrode on the other side.On a monophasic defibrillator, this is usually 360 joules.} 2.biphasic defibrilator - Biphasic defibrillators deliver current in two directions -On a biphasic defibrillator, this is usually between 120 joules to 200 joules

- 9. automated external defibrillator (AED)
- 10. implantable cardioverter-defibrillator (ICD), wearable cardiac defibrillator.
- 12. INDICATION ● PULESLESS VENTRICULAR TACHYCARDIA ● VENTRICULAR FIBRILATION
- 13. CONDRAINDICATIONS ● NON SHOCKABLE RHYTAM-ASYSTOL,PULSELESS ELCTRICAL ACTIVITY ● PATIENT WHO ARE CONCIOUS OR HAVE A PULSE ● MULTYFOCAL ATRIAL TACHYCARDIA{ Multifocal atrial tachycardia (MAT) is a cardiac arrhythmia caused by multiple sites of competing atrial activity. It is characterized by an irregular atrial rate greater than 100 beats per minute (bpm).}
- 14. MECHANISM ● DEFIBRILATOR DELIVERS A BRIEF ELECTRIC SHOCK TO THE HEART WHICH ENABLES THE HEART'S NATURAL PACEMAKER TO REGAIN CONTROL AND ESTABILISH A NORMAL HEART REAT ● 3 FEATURES ● -POWER SOURCE ● -CAPASITOR ● -2 ELECTRODE

- 19. STEPS OF CARDIOVERSION ● o perform cardioversion, follow advanced cardiac life support guidelines: ● Turn on the defibrillator. ● Select the appropriate energy level. ● Activate the synchronize mode by pressing the synchronize button. ● Check to verify that the machine is correctly sensing the R wave. ● Charge the machine to the ordered energy level. ● DELIVER THE SHOCK
