Safety considerations when using a defibrillator (AED)

This post is an excerpt from our free online AED course which covers the theory and practical aspects of using an Automated External Defibrillator (AED).


Automated External Defibrillators (AEDs) are very safe devices. However, there are a number of safety aspects to consider when using an AED.

WaterFirst aid for an electric shock

Water and electricity don’t mix! A towel should be provided along with an AED, this is to dry the patient’s chest.

Electricity will take the path of least resistance, so if there is water on the chest then the shock will travel through the water instead of the heart muscle.

 

Direct contactStand Clear

No one should touch the patient during delivery of the electrical shock by an AED. The AED will instruct everyone to stand clear. As the operator you should repeat this command and ensure everyone is clear of the patient. 

It is important however to deliver the shock as quickly as possible, so do not spend excessive time on this. 

 

Explosive environmentExplosive AED

An AED is delivering an electrical shock. Therefore there is always the risk of a spark. You should not use in AED in an explosive environment where there is a build up of flammable vapors. One example would be a gas/petrol station forecourt. 

Another consideration is the use of Oxygen by emergency medical staff. If Oxygen is being used, it should be at least 1 metre away from the AED and consideration should be given to the possibility of Oxygen building up in the atmosphere.

Hairy chest

Chest hair

The chest pads should be applied to bare skin. Excessive chest hair can disrupt the contact of the pads with the skin and result in burns when the electrical shock is applied.

A razor is supplied so you can shave excessive chest hair. 

Once again, do not spend a long time on this! Shaving cuts/rash is the least of your patient’s worries…
