When can you not use an AED?

You should not use an AED on someone who is conscious, responsive, breathing normally, or has a pulse, or if the environment is unsafe (wet, near flammable liquids/gases). Also avoid placing pads directly on pacemakers, medication patches, or excessively hairy chests (shave if needed), and never use one in a moving vehicle. An AED is for sudden cardiac arrest (unresponsive/not breathing), not heart attacks (pain/conscious).

What would stop you from using an AED?

Chest Hair

If this happens, the AED may not be able to read the patient's heart rhythm due to limited contact with the skin, or the shock can be delivered improperly. If you notice a patient's chest is hairy prior to applying the pads, immediately shave the chest.

In which situation would it be unsafe to use an AED?

The Person Is Wet or Lying on a Wet Surface

In wet conditions, AEDs can be dangerous to use, causing harm to the victim or the person providing the care. Since AEDs deliver an electrical shock, you must take specific care when treating the cardiac arrest victim. Never use an AED while submerged in water.

In which condition is a defibrillator not used?

If the person is breathing, this is a good indication that their heart is still pumping oxygen throughout their body, so the heart is still beating. Therefore, cardiac arrest is not an issue and defibrillator use is unnecessary.

Can you use an AED if there is a pulse?

An AED should be used when a person is unresponsive, not breathing properly, and does not have a pulse due to sudden cardiac arrest.

How to Use a Defibrillator (AED) - First Aid Training - St John Ambulance

When should you never use an AED?

Do not use an AED if the victim has/is:

1. Conscious and responsive.
2. Normal breathing or a pulse.
3. Submerged in water or in a wet environment *Note: Always be sure the person's chest is dry before applying pads.
4. Near or has been in contact with flammable substances, such as gasoline or propane.

Do you start CPR if there is a pulse?

Do you give CPR if there is a pulse but no breathing? Yes, Perform CPR: If a person is not breathing but has a detectable pulse, CPR (Cardiopulmonary Resuscitation) should be initiated immediately.

When is AED not applicable?

Here are instances when you must not use an AED: Non-Cardiac Arrest Situations: AEDs can treat sudden cardiac arrest where the heartbeats become irregular and jeopardize life. If a person is conscious, breathing, and has a pulse, he or she isn't suffering from cardiac arrest, so there would be no reason to use an AED.

What is the 3 minute rule in using a defibrillator AED?

The "AED 3-minute rule" is a guideline for Automated External Defibrillator (AED) program planning, recommending AEDs be placed so they are accessible and can be used within 3 to 5 minutes of a Sudden Cardiac Arrest (SCA) to maximize survival, as survival rates drop significantly with each minute of delay. It means AEDs should be centrally located with clear signage and easily reachable, often requiring multiple units in large facilities, to allow a rescuer 90 seconds to get the device and another 90 seconds to return to the victim.
 

Do you use an AED if someone's heart has stopped beating?

An automated external defibrillator (AED) is a portable device that can be used to treat a person whose heart has suddenly stopped working. This condition is called sudden cardiac arrest. AEDs are available in many public places, such as government buildings, schools, airports and other community spaces.

What are the three dangers before using the AED?

Check for the 3 dangers before use of AED: Ensure that there is no water, metal or flammable gasses.

What are the four non-shockable rhythms?

The two non-shockable cardiac arrest rhythms are pulseless electrical activity (PEA) and asystole. These are associated with the worst prognosis in cardiac arrest.

Why can't you drive with a defibrillator?

The driving risk posed by patients with ICDs for secondary prophylaxis is based on several factors: the probability that these patients will have a recurrence of another life threatening arrhythmia, the probability that such a repeat incident will cause impaired consciousness, the probability that such an event will ...

When does an AED not work?

Non-Shockable Rhythms

If someone experiences Asystole, CPR should be initiated immediately to provide the best chances of survival. If an Asystole rhythm is detected by an AED, it will not shock the patient, as defibrillation is not a viable treatment here.

Do you need to remove a bra when using an AED?

Nothing is higher priority than saving a life. This means that, if a patient is wearing a bra, it should be removed for an AED to deliver an effective shock. Removal of a bra means fabric will not get in the way of the AED pads.

How bad is your heart if you need a defibrillator?

You might need an ICD if you have a dangerously fast heartbeat called ventricular tachycardia or ventricular fibrillation. An ICD also may be recommended if you're at high risk of dangerous irregular heartbeats, usually because of a weak heart muscle. An ICD isn't the same as a pacemaker.

How long should you do CPR before using AED?

Compressions: Restore blood flow

If you are alone and didn't see the child collapse, start chest compressions and continue for about two minutes. Then quickly call 911 or your local emergency number and get an AED if one is available.

What is the 90 second rule for AED?

Per the “90-second rule,” AEDs must be retrievable within 3 minutes, leaving a bystander 90 seconds to get to the device and an additional 90 seconds to bring it back to the victim. Depending on the outline, this usually means having multiple AEDs on each floor or building.

What do they say before using a defibrillator?

It means "get clear" as in "get clear of the body" or "make sure nothing is touching this person" or "the area is clear". You're putting a lot of electricity through that person, and anyone touching them can get hurt.

Do you use a defibrillator if there is a pulse?

A defibrillator needs to be used for ventricular tachycardia (without a pulse) or for ventricular fibrillation. If you use it for any other kind of arrhythmia, it could give someone ventricular fibrillation and cardiac arrest.

Will an AED tell you to stop CPR?

The first thing the AED will do is determine whether an electric shock is needed by analyzing the person's heart rhythm. CPR should be stopped only while the machine is doing this analysis. If no shock is advised, it will tell you to resume CPR.

What should you avoid with a defibrillator?

With a defibrillator (ICD), you should avoid strong magnetic fields (junkyard magnets, MRI machines), powerful electrical equipment (welders, generators), certain medical procedures (like some types of lithotripsy), and activities that strain the implant site (heavy lifting, sudden arm movements) immediately after surgery, while always keeping your device ID card handy and informing healthcare providers.
 

When is CPR not recommended?

You should not perform CPR if the person is breathing, conscious, has a pulse, shows signs of irreversible death (like rigor mortis, decomposition, or decapitation), or if the environment is unsafe (fire, live wires, etc.), or if a valid Do Not Resuscitate (DNR) order is present, as CPR would be futile or against their wishes. 

What are the 3 R's of CPR?

The 3 Rs of CPR stand for Recognize, Respond, and Resuscitate, providing a simple framework for handling cardiac emergencies: Recognize the signs of cardiac arrest (unresponsiveness, no normal breathing), Respond by immediately calling emergency services (911/999) and getting an AED, and Resuscitate by starting chest compressions and rescue breaths (30 compressions to 2 breaths) until help arrives, according to the American Red Cross, AHA, and other sources like the Resuscitation Council UK.
 

Can you stop breathing but still have a pulse?

In respiratory arrest, the heart continues to beat, so the victim will still have a pulse, although their breathing has stopped. In contrast, during cardiac arrest, the heart is either beating irregularly or has stopped altogether, resulting in the absence of a pulse.
