With around 60,000 sudden cardiac arrests (SCAs) occurring every year in the UK, it is crucial that the public has access to a defibrillator, also known as an automated external defibrillator (AED).
While CPR keeps oxygenated blood flowing to vital organs, defibrillation can correct certain cardiac rhythms. Defibrillators are critical in determining life and death when someone experiences an SCA.
What is the Purpose of Defibrillation?
When a person experiences a cardiac arrest, indicated by a sudden collapse, unresponsiveness, and unconsciousness, a defibrillator can be a lifesaver. The life-saving device comes with pads that must be attached to the person’s bare chest. These pads deliver an electric shock to the heart, which can restore a normal rhythm.
Types of Defibrillators
Despite their importance, many people hesitate to use a defibrillator, fearing they might make the situation worse. This misconception can be costly It’s crucial that people feel confident using defibrillators. They are designed to be as easy to use as possible, guiding the user step by step through the life-saving process.
There are two main types of defibrillators:
Semi-automatic defibrillators which advise the user when to administer a shock.
Fully automatic defibrillators which administer the shock automatically if necessary.
Although training is not required to operate either type of defibrillator, semi-automatic defibrillators are typically used by trained health professionals.
