Frequently asked questions
What is an AED?
An AED is an Automated External Defibrillator. It is a portable, simple to use, computerized device. When someone suffers a sudden cardiac arrest it delivers a shock to the heart to allow it to resume its normal rhythm.
Where is my nearest AED Public Accessible Defibrillator?
All our defibrillators in the Greystones area are registered on Google Maps. Just search "AED" to locate the nearest one.
How do I donate to Greystones Community First Responders?

What is a CFR?
Community First Responders (CFR) are volunteers who respond to 999/112 calls that relate to cardiac arrests, chest pain, heart attacks, stroke, or collapse. CFRs operate within the community they live or work in. They carry a defibrillator and are able to provide early intervention (CPR + defibrillation) whilst waiting for the arrival of the ambulance. CFRs also provide support and reassurance to patients and their families when they are more vulnerable
Why is CPR so crucial?
CPR ensures vital organs, including the brain, receive essential blood and oxygen until medical help arrives at the scene.
What is a cardiac arrest?
A cardiac arrest is a sudden and severe medical emergency in which the heart abruptly stops beating effectively, causing the cessation of blood flow to the brain and other vital organs.
Here are the key points to understand about cardiac arrest:
Mechanism:
In cardiac arrest, the heart's electrical system malfunctions, leading to an irregular heartbeat (arrhythmia) or complete cessation of heartbeats (asystole).
Ventricular fibrillation (VF) and ventricular tachycardia (VT) are common arrhythmias associated with cardiac arrest.
Symptoms:
Sudden collapse.
Loss of consciousness.
Absence of pulse and breathing.
Occasionally, preceding symptoms like chest pain, shortness of breath, or palpitations might occur.
Causes:
Coronary artery disease (most common).
Severe physical stress.
Heart attack.
Congenital heart conditions.
Cardiomyopathy.
Severe electrolyte imbalances.
Drug overdose.
Diagnosis:
Immediate clinical assessment includes checking for responsiveness, breathing, and pulse.
An electrocardiogram (ECG) confirms the type of arrhythmia causing the cardiac arrest.
Treatment:
Immediate cardiopulmonary resuscitation (CPR) to maintain circulation and oxygenation.
Defibrillation to restore a normal heart rhythm, often via an automated external defibrillator (AED).
Advanced medical interventions include medications (like epinephrine), advanced airway management, and possibly procedures like cardiac catheterization once stabilized.
Prognosis:
Rapid response is critical; survival chances decrease significantly with each passing minute without intervention.
Long-term outcomes depend on the underlying cause, promptness of treatment, and the overall health of the individual.
Prompt recognition and immediate intervention are crucial for increasing the chances of survival and recovery from cardiac arrest.
