The AED treats only a heart in
ventricular fibrillation (VF)
, an irregular heart rhythm. In cardiac arrest without VF, the heart doesn’t respond to electric currents but needs medications.
Will an AED shock a beating heart?
An AED will automatically analyse the heart rhythm of a pulse less victim and, if the victim is in ventricular fibrillation (VF) or ventricular tachycardia (VT), shock the victim’s heart in an attempt to restore its rhythm to normal.
AEDs will not shock patients who
do not require a shock.
What does the AED shock do to the heart?
An AED is a type of computerized defibrillator that automatically analyzes the heart rhythm in people who are experiencing cardiac arrest. When appropriate, it delivers an electrical shock to the heart
to restore its normal rhythm
.
What heart beat Will an AED not recognize?
An AED cannot detect a pulse because it is an “
ELECTRO-cardiogram
“. It only detects electrical impulses. It is not able to detect the physical/mechanical beating of a heart.
What rhythms can you use a defibrillator?
Shockable Rhythms:
Ventricular Tachycardia
, Ventricular Fibrillation, Supraventricular Tachycardia.
What do you do immediately after AED shock?
Begin CPR
after delivering the shock. If no shock is advised, begin CPR right away. Perform 2 minutes (about 5 cycles) of CPR and continue to follow the AEDs prompts. If you notice obvious signs of life, discontinue CPR and monitor breathing for any changes in condition.
How many times can an AED shock?
The AED is programmed to reanalyze the victim’s rhythm and provide a shock as quickly as possible after each shock, to
a total of 3 shocks
.
Can a defibrillator start a dead heart?
To put it simply,
an AED will not restart a heart once it has completely stopped
because that’s not what it’s designed to do. As discussed above, the purpose of a defib is to detect irregular heart rhythms and shock them back to normal rhythms, not to shock a heart back to life once it has flatlined.
What should you do if the victim has a pulse but is not breathing?
- If the person is not breathing but has a pulse, give 1 rescue breath every 5 to 6 seconds or about 10 to 12 breaths per minute.
- If the person is not breathing and has no pulse and you are not trained in CPR, give hands-only chest compression CPR without rescue breaths.
Do you shock a flatline?
Defibrillation is not recommended
, despite commonly appearing on medical dramas as a remedy for asystole, but can be used for certain other causes of cardiac arrest.
What is the 1st thing you do to prepare the AED?
- 1Turn on the AED and follow the visual and/or audio prompts.
- 2 Open the person’s shirt and wipe his or her bare chest dry. …
- 3 Attach the AED pads, and plug in the connector (if necessary).
- 4Make sure no one is, including you, is touching the person.
Can CPR restart a stopped heart?
Cardiopulmonary resuscitation (CPR) will not restart a heart in sudden cardiac arrest
. CPR is just a temporary measure used to continue a minimal supply of oxygen to the brain and other organs. When someone is in sudden cardiac arrest, defibrillation is the only way to re-establish a regular heartbeat.
What to do if AED does not analyze rhythm?
Turn on the AED.
Stop CPR
and say, “CLEAR!” Ensure that nobody is touching the victim and push the “analyze” button on the AED machine. The AED will not be able to analyze the victim’s heart rhythm accurately during CPR.
What are the dangers of a defibrillator?
- Blood clots or air bubbles in the vein.
- Collapsed lung.
- Defibrillator malfunction requiring your doctor to reprogram it or replace it.
- Heart or nerve damage.
- Punctured heart or lung.
- Tearing an artery or vein.
- Unnecessary electrical pulses (impulses).
Can you get a defibrillator for free?

What are the only two rhythms an AED can shock?
AEDs advise a shock only to
ventricular fibrillation and fast ventricular tachycardia
.
