“A defibrillator is {an electrical} system that gives a shot throughout the center to assist deliver folks out of cardiac arrest,” explains James McNulty-Ackroyd, head of scientific initiatives and paramedic at St John Ambulance.

They’re usually labelled as an AED which is “an automatic exterior defibrillator, and it recognises when using one can be useful for the affected person. After we discuss about cardiac arrests, we discuss about shockable and non-shockable, and an AED is helpful when the center is specifically shockable rhythms”, he says.

When used, {the electrical} shock stuns the center to ship it again to its regular perform “from the correct shoulder down to the left armpit”.

The AED is aware of when it ought to work after the pads have been utilized, as a result of it “recognises the rhythm like an ECG routinely, and it’ll not shock if the center just isn’t in one of many related rhythms”.

When ought to you use one?

You solely need a defibrillator in an incident of cardiac arrest.

“They need to solely be used when the affected person just isn’t respiration usually, or the center has stopped,” explains McNulty-Ackroyd. “Their respiration could also be like a fish out of water, there isn’t any rhythm to it, there isn’t any actual air entry, or non-purposeful gasping.

“The center just isn’t pumping in that state of affairs – it isn’t working, however there’s some motion. They need a defibrillator and high-quality CPR (cardiopulmonary resuscitation).”

What ought to you be cautious of?

The excellent news is, there’s not a lot to fear about when using one.

“The very first thing the ambulance service will ask is, ‘Are they respiration?’ They may ask in the event that they’re awake and you will say ‘no’, as they’re in cardiac arrest.

“An ambulance can be despatched as the very best precedence in that space. Within the meantime, you ought to be using an AED and performing CPR.

“When you ring 999, they may inform you how to do CPR. Don’t worry about hurting somebody you are doing CPR on. That particular person is useless, they can’t really feel ache, in the event that they sit up and go ouch, they don’t seem to be in cardiac arrest.”

When using the defibrillator, “the primary pad goes on the higher proper, touching the clavicle [bone of the pectoral arch], and the opposite into the left armpit, good and excessive”, he explains.
