Snodland Community Responders


The Chain of Survival:

Thirty years ago, it was discovered that if a series of events took place, in a set sequence, a patient suffering from a sudden cardiac arrest stood a greater chance of survival.

Chain of Survial

These events are now known as the 'Chain of Survival'.

The First Link in the Chain of Survival - Early Access to Emergency Care:
Chain of Survial - Early Access

When Sudden Cardiac Arrest strikes, an immediate 999 call is crucial; a delay of just a few minutes could prove fatal. By quickly recognizing a medical emergency, a bystander can help save a life.

Could you recognize the symptoms of Sudden Cardiac Arrest?

They are:

- Unresponsiveness
- Loss of consciousness
- Lack of pulse
- Cessation of breathing

Sudden Cardiac Arrest is not the same as a heart attack. However, a victim of either condition requires an immediate 999 call.

Therefore the First Link in the Chain, is "Early Access to Emergency Care".

The Second Link in the Chain of Survival - Early CPR:
Chain of Survial - Early CPR
CPR or Cardiopulmonary resuscitation is the second link in the Chain of Survival; it is the link that can buy life-saving time between the first link (Early Access to Emergency Care) and the third link (Early Defibrillation).
During Sudden Cardiac Arrest, the heart twitches irregularly most often due to ventricular fibrillation (VF) and cannot pump oxygenated blood efficiently to the brain, lungs, and other organs. The victim quickly stops breathing and loses consciousness.

However, prompt CPR can help sustain life during VF. The mouth-to-mouth breathing and chest compressions help oxygenated blood flow to the person's brain and heart, until defibrillation can attempt to restore normal heart pumping.

The Third Link in the Chain of Survival - Early Defibrillation:
Chain of Survial- Early Defib

Although it is an important link in the Chain of Survival, CPR alone cannot fully resuscitate a person in Sudden Cardiac Arrest (SCA). Early defibrillation is the third and perhaps most significant link. Most SCA victims are in ventricular fibrillation (VF), an electrical malfunction of the heart that causes the heart to twitch irregularly.

Defibrillation, the delivery of an electrical shock to the heart muscle, can restore normal heart function if it occurs within minutes of SCA onset.

When CPR and defibrillation are provided within eight minutes of an episode, a person's chance of survival increases to 20%. Community Responders, like the Snodland Community Responder Team, are trained to use and carry a life saving heart Defribrillator. First Responders normally use a version of Defribrillator called an "AED" - or Automated External Defribrillator.

See our training and equipment section for more details about the AED's we use.

When these steps are provided within four minutes and a paramedic arrives within eight minutes, the likelihood of survival increases to over 40%.

The Fourth Link in the Chain of Survival - Early Advanced Care:

Chain of Survial - Advanced Care

The fourth link in the Chain of Survival is advanced care. Paramedics and other highly trained Emergency Ambulance Medical Personnel provide this care, which can include basic life support, defibrillation, administration of cardiac drugs, and the insertion of endotracheal breathing tubes. This type of advanced care can help the heart in VF respond to defibrillation and maintain a normal rhythm after successful defibrillation.
The trained Ambulance personnel monitor the patient closely on the way to the hospital, where more definitive diagnostic evaluation can occur.
