When Is An AED Used In CPR?

The Critical Role of CPR

What is CPR?

Cardiopulmonary resuscitation (CPR) is a lifesaving technique employed when someone's heartbeat or breathing has ceased.

Life-Saving Importance

Immediate initiation of CPR can significantly increase the chances of survival and reduce the risk of permanent injury to the brain and other vital organs.

What Is an AED?

Definition and Role

An Automated External Defibrillator (AED) is a portable device used to administer an electric shock through the chest wall to the heart. This shock can potentially restore a regular heart rhythm in certain cases of cardiac arrest.

Why an AED?

An AED can make a significant difference in survival rates for cardiac arrest when used in conjunction with CPR.

Timing Matters: When to Use an AED

Recognizing the Need

The use of an AED is generally warranted in the case of unresponsive individuals who are not breathing or only gasping.

As Soon As Possible

An AED should be used as quickly as possible upon determining that a person is unresponsive and not breathing. Time is of the essence.

Steps for AED Use

Initial Assessment

Upon identifying an unconscious and non-breathing individual, CPR should be initiated and an AED should be located or called for immediately.

AED Deployment

Once the AED arrives, it should be turned on and the electrode pads should be applied to the patient's bare chest, as indicated by the instructions.

Follow Prompts

The AED will give vocal instructions and possibly text-based prompts to guide the rescuer through the process.

CPR and AED: A Coordinated Approach

Interplay of Techniques

While waiting for the AED to arrive or be set up, CPR should be continued to maintain some level of oxygenation to the brain and vital organs.

After the Shock

If an AED delivers a shock, or advises against it, CPR should be resumed immediately for two minutes before checking the patient’s status and possibly using the AED again.

Public Access

AEDs are increasingly available in public places, and laws often require that clear instructions be included with publicly accessible units.

Education and Preparedness

Learn the Skills

Taking a recognized CPR and AED course can prepare you to act swiftly and effectively in a cardiac emergency.

Spread Awareness

The more people who know how to properly use an AED and perform CPR, the better the overall community response to cardiac emergencies will be.

Using an AED during CPR can significantly increase the likelihood of survival in certain types of cardiac arrest. Always seek professional training to keep up to date with the latest best practices.
