Defibrillators are incredibly easy to use, talking you through every step.
You can use these machines despite not having any training due to the easy step-by-step instruction they give you.

Why do we need defibrillators?

30 years ago it was discovered that if four things happened in a certain order a person suffering a cardiac arrest would have an increased chance of survival.
This is called the chain of survival:

Early recognition
Being able to recognise that someone is in cardiac arrest and knowing that you need to act quickly and call 999 is the first stage.
Early CPR
CPR is a vital part of the chain of survival. This will keep the blood pumping around the body.
Early defibrillation
A defibrillator sends a shock to the heart, if required. This stops the heart in order for the heart to then restart its normal rhythm.
Advanced care
This is when the paramedics and the doctors come in. Members of the public carry out the first three stages and begin the process for the forth by calling 999.

Why do we need defibrillators?

A cardiac arrest is when the heart goes out of its normal rhythm. There is no signs of life; the person will not be breathing normally , therefore their heart will not be beating normally. Electrical signals cause the heart to pump blood around the body. The electrical signals start from a point in the heart (the pace maker) which then causes other parts of the heart to react to eventually reach a pumping motion. When a cardiac arrest strikes and the heart goes into ventricular fibrillation, signals are firing from all over the heart, creating a disorganised rhythm.

How often do they happen?

Cardiac arrests are very sudden and can often come with no prior warning. 30,000 out of hospital cardiac arrest happen each year in the UK. This includes 12 children every week, 80% of these are in the home.

You are most likely to do CPR on someone that you know. Do you know how to do CPR?. Do you know where your nearest defibrillator is?

How do defibrillators work?

So how does a defibrillator work?

Once you have identified the person is in cardiac arrest you should attach a defibrillator to the persons chest.

The defibrillator will then ask you to step off the patient and analyses the patients heart rhythm.

The defibrillator is looking for one particular heart rhythm; Ventricular Fibrillation (VF) If it finds VF it will recommend a shock and ask you to press the button. If not, there will be no shock advised.

If we placed a defibrillator on the chest of a person that is breathing, their heart rhythm would be of a normal pattern (and not VF) and therefore no shock will be advised.

Regardless of shock or no shock advise, the machine will advise you to carry out CPR. Every two minutes the defibrillator reanalyses and will then advise shock of no shock again.

How do defibrillator cabinets work?

The secure cabinets

The cabinets are thermostatically controlled to maintain the defibrillator pads at a temperature at around 5 degrees.
The specialist cabinets will be purchased from a local company.

The cabinets are mounted on the wall and plugged in a three pin plug on the inside of the wall.
Our installation team will take charge of installing them for you. The cost to run the cabinet is between £5 and £8 a year.
