There are around 60,000 cases of sudden cardiac arrest each year in the UK. The majority of these could be treated with immediate application of a defibrillator, potentially saving a significant number of lives.

  • Sudden Cardiac Arrest

    Sudden cardiac arrest (SCA) is a leading cause of premature death, but with immediate treatment many lives can be saved. SCA occurs because the electrical rhythm that controls the heart is replaced by a chaotic disorganised electrical rhythm called ventricular fibrillation (VF).

    Most cases of SCA are due to an abnormality of the heart’s electrical rhythm called ventricular fibrillation (VF)

    AEDs are easy to use, compact, portable and very effective. They are designed to be used by lay persons; the machines guide the operator through the process by verbal instructions and visual prompts. They are safe and will not allow a shock to be given unless the heart’s rhythm requires it.

    Most cases of SCA are due to an abnormality of the heart’s electrical rhythm called ventricular fibrillation (VF) in which the electrical impulses that normally control the heart become chaotic and uncoordinated. The heart stops beating (i.e. it ceases to act as a pump) and the circulation of blood stops. Death is inevitable unless the condition is recognised promptly and defibrillation is carried out. Defibrillation is the use of a high-energy electric shock that stops the chaotic rhythm of VF and allows the normal, organised, electrical rhythm of the heart to re-start. This can allow the pumping action of the heart to return.

    The term ‘heart attack’ is often used to refer to SCA, but this is incorrect. A heart attack (or myocardial infarction) occurs when an artery (‘fuel pipe’) supplying the heart with blood (‘fuel’) becomes blocked. This usually causes chest pain and leads to damage to some of the muscle of the heart. It may cause SCA, particularly in the early stages, but this is by no means inevitable.

  • IPAD SP1

    The new iPAD SP1 Semi-Automatic AED is the latest in the range of intelligent public access defibrillators from one of the world’s leading manufacturer's of clinical defibrillator monitors. Designed to be used by minimally trained individuals, the iPAD SP1 is suitable for use almost anywhere that people gather, whether it’s within the workplace, a shopping centre or a hospital, the iPAD SP1 makes saving lives easier than ever.

    Easily switch from Adult to Child mode without changing pads with safety cover preventing accidental switching. Smaller child pads are also available but are not a requirement for effective use.

    Ambient noise detector measures level of background noise and adjusts the volume of the voice prompts accordingly, which is ideal for noisy environments such as public places, factories, warehouses, schools etc.

    Integrated pad storage – electrode pads are stored, pre-connected, in a clear compartment on the underside of the unit. Pads are easily removed by pulling on the exposed tab. The pads are always ready for use and easily checked.

    CPR Detection – the iPAD SP1 detects if CPR is being performed when appropriate. If CPR is not being performed, voice prompts encourage the responder to ‘perform CPR’. If CPR is being performed, voice prompts encourage the responder to ‘continue CPR’. Throughout a rescue, the responder can decide whether or not the CPR metronome is heard.

    The visual indicator shows at a glance: battery life, unit status & pad status, with unit performing a self-test every day to ensure functionality.

    Internal memory stores the last 5 events/3 hours of data. Data can be transferred via the built in SD card and IrDA (infrared) ports and can be reviewed via PC software and useful ‘handover’ information can brief ambulance crews via audio.

    The IP55 rating ensures that the iPad SP1 can be used in harsh environments and also benefits from being splashproof.

    The iPad SP1 has a 7 year manufacturer's warranty, 5 year or 200 shock warranty on the battery and pads expire 3 years from manufacture.

  • What is an AED?

    An AED is a sophisticated electronic device designed to administer an electric shock to a patient exhibiting an irregular heart rhythm; the purpose being to return the patient to normal, or sinus, rhythm.

  • Automatic vs. Semi-Automatic?

    An automatic defibrillator delivers an electric shock to the patient without any intervention. A semi automatic defibrillator monitors the patient’s heart rhythm and if an electric shock is required the operator is instructed to press a button the the device which then delivers the shock.

  • Do I need training?

    Automated defibrillators are designed to be used by non medical professionals in emergency situations. Increasingly sophisticated devices with voice prompts and patient monitoring make the process increasingly easier. Nevertheless, in life and death situations a solid understanding and some practical experience can go a long way to improving the application of treatment.
