Children and circulatory arrest

When a small child (<25 kg) has a circulatory arrest, this usually has a different starting cause than a fibrillating heart. Examples of this are:

The right treatment in this case is:
-dial 999 or 112
-start CPR

Because it is not always clear what caused the circulatory arrest the AED unit will always have to be brought.
If a victim weighs less than 25 kg the use of child pads is recommended but not required.

Reasons for using child pads are:
-the AED uses a special child-database for the heart analysis (that is because the regular heart rhythm of a small child is faster or even much faster than for an adult);
-the surge of the AED will revert from 150 Joule to 50 to 80 Joule.

The adjustment of the database, protocol and Joules varies per brand. This document is based on the Philips AED’s

Reasons not to use child pads are:
-having to change electrodes in the middle of a panic situation, which can lead to delays.
-A child key or switch button can be a solution;
-the AED can also be used with adults’ electrodes for use on children who weigh less than 25kg.
-The Dutch Resuscitation Council writes in the currently applicable guidelines: Standard AEDs may also be used for defibrillation of infants and children if there is no custom AED available for them.
-with children under 25kg circulatory arrest in which fibrillation is the cause is less than 5x a year.

It is better for a child to use child pads, but in emergencies the standard AED should be used.

Remark: for children under 25kg the pads will have to be patched in a different way. See the picture below (one electrode pad on the rear between the shoulder blades and one electrode pad on the breastbone between the nipples: The hands should in this case be placed on the electrode pads during resuscitation).

Quality of BLS when using different public AED’s

Earlier this week a very interesting science article was published about the effect of AED voice prompts in relation to the quality of BLS (in particular the duration of the interruptions during the chest compressions). Given the importance of this article we have decided to take this publication entirety over. This is a study of a German team from the University Hospital in Dresden and published on June 21, 2015 in the Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine.

Quality of basic life support when using different commercially available public access defibrillators

Basic life support (BLS) guidelines focus on chest compressions with a minimal no-flow fraction (NFF), early defibrillation, and a short perishock pause. By using an automated external defibrillator (AED) lay persons are guided through the process of attaching electrodes and initiating defibrillation. It is unclear, however, to what extent the voice instructions given by the AED might influence the quality of initial resuscitation.


Using a patient simulator, 8 different commercially available AEDs were evaluated within two different BLS scenarios (ventricular fibrillation vs. asystole). A BLS certified instructor acted according to the current European Resuscitation Council 2010 Guidelines and followed all of the AED voice prompts. In a second set of scenarios, the rescuer anticipated the appropriate actions and started already before the AED stopped speaking. A BLS scenario without AED served as the control. All scenarios were run three times.


The time until the first chest compression was 25 ± 2 seconds without the AED and ranged from 50 ± 3 to 148 ± 13 seconds with the AED depending on the model used. The NFF was .26 ± .01 without the AED and between .37 ± .01 and .72 ± .01 when an AED was used. The perishock pause ranged from 12 ± 0 to 46 ± 0 seconds. The optimized sequence of actions reduced the NFF, which ranged now from .32 ± .01 to .41 ± .01, and the perishock pause ranging from 1 ± 1 to 19 ± 1 seconds.


Voice prompts given by commercially available AED merely meet the requirements of current evidence in basic life support. Furthermore, there is a significant difference between devices with regard to time until the first chest compression, perishock pause, no-flow fraction and other objective measures of the quality of BLS. However, the BLS quality may be improved with optimized handling of the AED. Thus, rescuers should be trained on the respective AED devices, and manufacturers should expend more effort in improving user guidance to shorten the NFF and perishock pause.


The survival rate after out-of-hospital cardiac arrest (OHCA) is below 10 %, despite considerable efforts on the part of emergency medical services and hospitals to optimize treatment [1]. The key problem is that in cases where no lay rescuers initiate basic life support measures, blood flow to the brain is restored only when professional rescuers start chest compressions, which is often too late for recovery without serious sequelae. The current American Heart Association and European Resuscitation Council guidelines for cardiopulmonary resuscitation (CPR) outline immediate recognition, early CPR, and rapid defibrillation as the key elements of the chain of survival [2],[3]. Furthermore, the 2010 update of the CPR guidelines was designed to ensure high quality chest compressions and minimize interruptions to maximize organ perfusion.

Automated external defibrillators (AED) reliably recognize shockable cardiac rhythms and allow defibrillation to be performed by non-physicians. Furthermore, the time from collapse to defibrillation determines survival in patients with OHCA; each delay of one minute increases mortality by 10 % [4]. Thus, efforts have been increasingly undertaken in the past few years to make AEDs available to the public, especially in high-traffic public areas. By decreasing the time to the first defibrillation, the survival rate after OHCA has increased up to 74 % [5]. Many different AEDs are commercially available, and modern devices defibrillate with biphasic waveforms, resulting in high conversion rates. AEDs seem to be perfect “resuscitation devices” for lay rescuers, as they not only analyse the rhythm and shock the patient if indicated, but they also provide essential instructions regarding the BLS algorithm. The AED provides audible instructions to activate the emergency medical system (EMS), check for vital signs, and initiate chest compressions. However, as early as 10 years ago, Fleischhackl studied how lay people operate an AED and found alarming results; the time to the first shock and the proportion of study volunteers who started chest compressions after being prompted by the AED varied widely [6].

To our knowledge, no previous study has investigated interruptions of chest compressions during BLS when an AED is used. The objective of this study was to evaluate the quality of BLS when an AED is used with a special focus on the no-flow fraction and the perishock pause.


This study complies with the Declaration of Helsinki, and the locally appointed ethics committee approved the study protocol (EK 127042012). Two standard test scenarios were scripted using a Code Blue III Advanced Life Support manikin (Gaumard Scientific, Miami, FL/ USA). The manikin has conductive skin regions allowing defibrillation with real AEDs through the standard self-adhesive pads. The simulator can be connected to a laptop computer, and the Gaumard software (Gaumard UI- records chest compressions, ventilations, and defibrillation.

Eight AEDs were available for the study: Heartsave PAD (Metrax, Rottweil, Germany), Philips HS1 (Philips Medical Systems, Bothell, WA, USA), Lifeline VIEW AED (Defibtech, Guilford, CT, USA), Lifepak CR Plus (Medtronic Physio-Control, Redmond, WA, USA), PowerHeart G5 (Cardiac Science, Bothell, WA, USA), Fred Easy Life (Schiller AG, Baar, Switzerland), AED Plus (Zoll Medical Corporation, Chelmsford, MA, USA), and Cardiolife AED 2100 (Nihon Kohden Corporation, Tokio, Japan). All AEDs were provided by the manufacturers, except for the AED Plus. The language of all AEDs were set to German. The manufacturers were asked to provide a device that is used as a public access defibrillator. Each of the AEDs was evaluated in pre-scripted basic life support scenarios with an adult patient in persistent ventricular fibrillation (VF, scenario 1) or asystole (scenario 2). Each AED was tested three times in both scenarios. The scenario duration was 5 minutes. One BLS instructor (MK) performed single-rescuer BLS using an AED and following the voice prompts. BLS was performed according to the 2010 ERC guidelines, with a ratio of 30 chest compressions to 2 ventilations. The respective AED was switched on immediately at the start of each scenario. The BLS instructor followed all voice prompts of the AED exactly as provided. The rescuer listened to each voice prompt and started the appropriate action immediately after the AED finished speaking.

All AEDs were tested again in a second set of scenarios (a total of three times each in scenarios 1 and 2). However, the BLS caregiver followed the optimal sequence of actions, with minimal interruptions in chest compressions. This was done by starting the appropriate action as early as possible during the AED voice prompt. Some actions can be initiated before the AED has started that particular instruction; for example, chest compressions were resumed immediately after each shock.

A third scenario, 5 minutes in duration, was run without the use of an AED to calculate the difference in the no-flow fraction between BLS with and without the use of an AED. This scenario was also repeated three times.

During all scenarios with the use of an AED, the following values and time intervals were measured:

  • Time until first chest compression
  • Time until the first rhythm analysis was completed
  • Duration of rhythm analysis
  • Time until first shock (in scenarios with ventricular fibrillation)
  • Time between first shock and the beginning of the second rhythm analysis (in scenarios with ventricular fibrillation) or time between completion of the first rhythm analysis and the beginning of the second rhythm analysis (in scenarios with asystole)
  • Perishock pause: Time from last chest compression (CC) before a shock until the first chest compression after the respective shock (in scenarios with ventricular fibrillation)
  • No-flow fraction (NFF): Fraction expressed as a quotient of the no-flow time and the total time without spontaneous circulation.

The mean and standard deviation were calculated for all parameters for each AED.

Data analysis and statistics

All data were analysed using IBM SPSS software (Version, Armonk, NY). After ensuring homogeneity of variances by the Levene test, univariate ANOVA was used for repeated between-AED model analyses and was followed by Sidak post-hoc testing and multiple comparison alpha adjustment.

Within each AED model, a paired t-test was used to compare the effects of performing the optimal sequence of actions compared to standard AED voice-prompt-guided procedures.

Due to the strongly statistically significant difference between the AED models as shown in Tables 1, Table 2, Table, 3 and 4, only a lack of significance is indicated. If not otherwise indicated, the between AED-model comparison of the respective parameters is statistically significant at a p-value of <0.01.

Table 4. BLS with the use of an AED in scenarios with persistent asystole: optimized sequence of actions



Data for BLS with an AED when the AED voice prompts were strictly followed are shown in Table 1 for VF and in Table 2 for asystole. Table 3 (VF) and Table 4 (asystole) present the data from the AED scenarios with an optimized sequence of actions during BLS. An English translation of the voice prompts in a scenario with shockable rhythm is provided for all AEDs that were evaluated (Additional file 1).

In the scenarios with persistent ventricular fibrillation and without an AED, the rescuer started chest compressions after 25 ± 2 seconds. When using an AED and following the voice prompts, the mean time until the first chest compression ranged from 50 ± 3 seconds to 148 ± 13 seconds in the first set of scenarios (the action was started after the AED finished speaking). In the second set (the optimized sequence of actions), the interval to the start of chest compressions ranged from 16 ± 2 to 41 ± 1 seconds.

The no-flow fraction during BLS without the use of an AED was 0.26 ± 0.01. However, the use of an AED increased the NFF in all scenarios: in the first set of scenarios, the NFF ranged between 0.37 ± 0.01 and 0.72 ± 0.01 (VF) and between 0.40 ± 0.01 and 0.72 ± 0 (asystole). In the second set of scenarios (the optimized sequence), the variability in NFF decreased to 0.32 ± 0.01 – 0.37 ± 0.02 for VF and 0.33 ± 0.01 – 0.41 ± 0.01 for asystole, respectively. The differences between the devices were statistically significant, except for three models of VF and one model of asystole. However, the NFF still was significantly higher with all devices compared to BLS without the use of an AED (p < 0.01).

In the first set of scenarios, the shortest value for the perishock pause was 12 ± 0 seconds, whereas the longest pause was 46 ± 0 seconds. In the scenarios with an optimized sequence of actions, the perishock pause was shorter, ranging from 1 ± 1 to 19 ± 1.


This is the first study to investigate the no-flow fraction, perishock pause, and other objective quality parameters during BLS using eight different available public access defibrillators in a simulator setting.

As expected, our study found higher NFF values in BLS scenarios that used an AED compared to those that did not. Furthermore, we found extremely high NFF values in these scenarios with a high variability between the different models. In all cases, the perishock pause was always much longer than advised by the current resuscitation guidelines. However, when the rescuer optimized the sequence of actions and acted immediately before or after the voice prompt started (Tables 2 and 4), the NFF and the perishock pause both were significantly reduced, with minor variability.

The chest compression fraction has been identified as a cardiac resuscitation quality parameter that is associated with the survival rate [7],[8]. A small study from the PAD trial evaluated the quality of BLS and found very high values for NFF (0.52 to .83) when lay rescuers performed BLS and used an AED[9]. Two studies have shown that chest compressions during prehospital life support are interrupted in approximately half of the time [10],[11]. The current international resuscitation guidelines demand high quality chest compressions with minimal interruptions. Well trained teams can provide life support with NFFs as low as 0.24 [12]. In these cases, a defibrillator capable of manual defibrillation was used. However, an observational study showed that the NFF during in-hospital BLS with the use of an AED can be as low as 0.30 when nurses repetitively perform the BLS/ AED algorithm in a BLS training course [13].

The NFF during scenario 2 (asystole) was comparable to that of scenario 1 and was significantly higher than the value for BLS without an AED for all AEDs. Recent studies have found that only between 24 and 40 % of patients with OHCA are in a shockable rhythm when the ambulance arrives [14]. At the time of collapse, the proportion of patients who are in a shockable rhythm is higher, but there is still a considerable number of patients who are in a non-shockable rhythm. For those patients, the use of an AED resulting in a high NFF is harmful and may increase mortality.

The NFF was lower for six devices (VF) and 5 devices (asystole) during the scenarios with an optimized sequence of actions. The NFF was similar in all devices and was below .40, except for one AED in asystole. This set of scenarios can be compared with trained lay rescuers or healthcare professionals after practice with a specific AED. The first set of scenarios involves untrained lay rescuers using a public access defibrillator while strictly adhering to the guiding voice prompts. It is concerning that the use of commonly available AEDs, which are designed to be used by lay rescuers, might lead to poor quality life support, with chest compressions being delivered less than 30 % of the time. The wide difference between the standard use and the optimized sequence of actions implies that the human-machine interface of the devices is a major problem; manufacturers should expend considerably more effort on the development of optimal user guidance to ensure the best possible performance, even when used by lay rescuers who have never before observed a patient in cardiac arrest and who perhaps have never received BLS training.


Perishock pause

Survival to hospital discharge is substantially more likely when the first documented rhythm is shockable rather than nonshockable [15]. When a defibrillator is used, the perishock pause has been identified as an independent predictor of survival [16]. A substantial delay in providing chest compressions has been observed in the post-shock period with AED-equipped first responders [17]. As Cheskes et al. reported, a pre-shock pause of ≥ 20 seconds and a perishock pause of ≥ 40 seconds are predictors of worse survival after shockable cardiac arrest. Based on a log-linear model, any five seconds increase in the perishock pause interval decreases the rate of patient survival to hospital discharge by 14 % [16].

Therefore, the international guidelines for resuscitation advise a perishock pause of less than 5 seconds. This recommendation was not fulfilled in any of the AEDs tested in the first set of scenarios with strict voice prompt adherence. We noted that some AEDs do not permit chest compressions during the charging period, resulting in an almost fourfold variation in the perishock pause between the different devices. This variation in duration may be responsible for the variable success in patient resuscitation. In 2004, Snyder et al. alluded to the problem of the AED-determined variation in hands-off times[18]. However, the manufacturers may have implemented an algorithm, which does not prompt the rescuer to provide chest compressions for some seconds during charge and then take hands off for the shock as this may confuse lay persons. We need further studies to find out whether real lay rescuers are able to follow such an algorithm with minimised perishock pause.

The perishock pause was reduced in nearly all of the tested AEDs when the optimized sequence of actions (in the second set of scenarios) was used. Two devices met the demands of the current guidelines, implying that there is significant potential for improving user guidance. The necessary changes are small and include optimization of the device algorithms and voice prompts. Determining the best practices for AED voice prompting will be the subject of a follow-up analysis of the present dataset.

Time until first chest compression

A lone lay rescuer following the AHA guidelines for BLS would call an ambulance, fetch an AED (if available), and return to the patient to start life support [2]. However, when switching on the AED and following the voice prompts, the beginning of chest compressions is delayed for up to nearly 2.5 minutes. This stands in sharp contrast to what is taught in courses on cardiac resuscitation around the world: the check – call – compress paradigm, in which chest compressions are started as early as possible, and any unnecessary interruptions are avoided.

A retrospective analysis of OHCA cases found no benefit of bystander CPR for patients receiving the first shock between 1 and 5 minutes after collapse, whereas survival was much higher for patients receiving bystander CPR when the first shock was applied after more than 11 minutes [19]. However, even for the patients receiving the first shock within 5 minutes, this study does not answer the question whether shock first (and delayed start of chest compressions) or CPR first (and later application of the shock) is superior with regard to the survival rate. However, modern AED devices should guide the lay rescuer to soonest possible defibrillation, while assuring a short time until the first chest compression.

Duration of rhythm analysis

The duration of rhythm analysis depends solely on the technical specifications of the respective device. This value varied by about 100 % between the devices. However, the absolute difference between the fastest and slowest analysis duration was only 8 seconds. One potential future improvement is hands-on rhythm analysis during chest compressions. Making a serious effort to develop optimized devices may lead to shorter time intervals. However, a much larger effect on shortening the NFF among layperson rescuers could be achieved by inventing devices with improved usability and voice prompts.

Wide variation of CPR quality between different AED models

When a lay rescuer provides BLS and uses an AED model with which he or she is not familiar, the CPR quality depends critically on the AED device. We found extensive variations in important parameters such as the NFF and the perishock pause. Most clinical studies investigating the effects of the use of AED were not stratified by the AED model used. Future studies, especially large resuscitation registries, should always consider the defibrillator model. Even the firmware version might provide important additional information, as different versions may differ in terms of user guidance and thus lead to variations in the quality of BLS.

In this study, a trained person used the AEDs. However, lay rescuers use these machines in real cardiac arrest situations. As they are under high stress and may be afraid of using an AED, the voice prompts should be clear and precise. Some models provide more detailed voice prompts than others (see Additional file 1). We do not know whether more details result in better performance and less mistakes when the AED is used by untrained real lay rescuers and whether this may compensate the longer and more frequent interruptions. The intention of very precise instructions may be to assure a shock when used by a heterogeneous group of lay rescuers. However, if a lone rescuer places an emergency call and fetches an AED before returning to the patient, 2 minutes or more may already have been expired. At this time, soonest beginning of chest compressions is important and this should be taken into account when developing AEDs and when elaborating user guidance. Further research should be done to study the quality of BLS when lay rescuers use AEDs.


This study was performed in a simulator centre, and a BLS instructor evaluated the devices. The quality of BLS in real cases may vary from that in this study.

With some AEDs, lay rescuers may not understand some voice prompts or they could experience usability problems that could not been found in the present study but may result in even worse BLS performance.


Our study presents concerning results regarding the quality of BLS when using an AED and following all voice prompts. We found a broad variation in the parameters, which were evaluated in the study, including the time until the first chest compression, the no-flow fraction, and the perishock pause. The manufacturers should take these results into account when developing the next generation of AEDs to be used by layperson rescuers: The protocol of the respective device should meet the best available standard as a high quality of BLS is of utmost importance for optimal survival rates.

No excuse for AED behind lock and key

Medisol from Middelburg the Netherlands with web shops throughout Europe and market leader in the Netherlands for the Automated External Defibrillators  AED  does not sell AED cabinets anymore with a keypad or pin lock. The reason for this is that an AED should be accessible for everyone. Medisol has already taken initiatives in the past to discourage the use of locks on AED cabinets.

“Since the start of selling AEDs we find it difficult to keep an important life saving device behind lock and key”, according to Medisol. During our work for the ambulance service we have experienced that AED heart defibrillators were of no use, because nobody knew the pin lock or had the key for the AED cabinet. We now have made a statement and have stopped the sales of AED cabinets with locks or pin lock systems. The AED does not belong  “behind bars”. For crying out loud  “have you ever seen a fire-extinguisher that you needed a key for? “

Medisol asks that the Netherlands  take a special position within Europe. In other countries AED cabinets with a pin lock are nowadays a phenomenon. Abroad there have been several initiatives to stimulate the public character of AEDs. The English Resuscitation Council and the British Heart Foundation have mentioned to give no subsidy to AED-projects where AEDs are placed in a locked cabinet. section guidelines 2010: the use of automated external defibrillators/ page 34

Medisol has been longer active with the subject better achievability  of  AED heart defibrillators. In 2009 Medisol associated with a few large manufacturers and  AED suppliers and launched the website “Stolen AED”. On the website achievability of  the AED is stimulated by giving information. The risk of someone getting an heart attack is much bigger than an AED being stolen out of a cabinet . But  there will always be customers who won’t give it enough thought and will choose an AED wall cabinet with a (pin-) lock.

We want to have a clear conscience on this delicate matter. Someone could die because of an AED placed in a locked cabinet. The past years we have advised our customers not to choose for a locked system, but against all advice in they have continued to do so. “Since 2013 we offer only free-access cabinets”, according to Medisol.

What is the reason AED electrode pads have a limited shelf life?

You must have noticed when you have an AED that the electrode pads have a limited shelf life. What is the reason for this?

The pads have two main functions.  Attached to the AED the pads measure the heart rhythm to judge if a life-saving shock is required.  If the AED recommends a shock must be given then it will give a therapeutic shock using the same electrode pads. For use of these main functions  firm adhesion to the  skin is of great importance.

The electrode pads use an adhesive gel that conducts

For  purpose of adhesion to the skin electrode pads are equipped with a gel that not only has adhesive properties but also conducts the electric current. After a while the gel on the pads may dry out in the packaging, causing the chemical composition of the gel to change.  This will  result in  lower conduction of the electric current.  The AED may have problems with the analysis if the quality of the conducting signal reduces.  Also the electrode pads will be less adhesive. This can be a problem when chest compressions have to be applied. They may shake loose from the skin or become displaced. The AED will then be less able of providing a therapeutic shock, hence reducing its life-saving function.

The solution

Because of changes in the chemical composition of the pads the manufacturer can guarantee their quality only for a specific period of time after production. This is the reason that the pads are supplied with a “best before date”. The shelf life varies, depending on the brand and type and runs from 12 to 60 months. It is important that during the periodic inspection of the AED the electrode pads are also checked and, where necessary replaced.

Defibrillator delivery could help to save lives in Tring

Tring Athletic Football Club has been equipped with a life-saving new defibrillator, with the help of The Football Association and the British Heart Foundation. More than 900 defibrillators have been made available to clubs at Steps 1 to 6 of the National League System and clubs in the Women’s Super League to help save the lives of cardiac arrest casualties. Tring Athletic is the latest club to install a defibrillator, giving players, staff and fans access to the equipment needed to save lives in their community. The club was also given information about hands-only CPR, which was made famous for the BHF by football legend Vinnie Jones. Two-thirds of the cost of the defibrillator was provided to the club by The FA and BHF. Tring Athletic chairman Mick Eldridge said: “This vital piece of equipment could prove to be the difference between life and death and it’s a welcome addition to this club and its community. “The FA and BHF have made it possible for Tring Athletic to be part of the drive to improve the UK’s poor cardiac arrest survival rates. “Along with CPR, a defibrillator is a vital link in the chain of survival and we’re lucky that we now have the skills and equipment at the club to save a life.” The British Heart Foundation has already helped place 11,000 defibrillators in the community since 1996.

Since the charity launched hands-only CPR last year, more than 30 lives have been saved by the technique.

Couple donate defibrillator in Stotfold in memory of 13-year-old son

A husband and wife who lost their teenage son to a heart condition have donated another defibrillator as part of their lifesaving campaign. Barrie and Brenda Irons, whose son David died at just 13 years old, donated the equipment – the 29th defibrillator they have given away – to Stotfold Mill in Mill Lane. Making the donation on March 5 as part of the Big Shock campaign from cardiac charity SADS UK, Brenda visited the site while The East of England Ambulance Service provided training. Barrie Irons said: “We are delighted that we are able to donate a defibrillator to Stotfold Mill. The defibrillator is easy to use as it tells you what to do and won’t give a lifesaving shock unless it needs to. “If a person suffers a cardiac arrest the quicker the defibrillator is used the better chance there is of survival.” Anne Jolly, founder of SADS UK, said: “Barrie and Brenda Irons have raised a lot of awareness in their community, letting people know that cardiac arrest can affect all ages. “Through their generosity their local community has benefitted from having defibrillators, along with lifesaving training on each site. “If CPR is used it gives a person a five per cent chance of survival, but coupled with using the defibrillator it increases the chance of survival to over 50 per cent. “This is why SADS UK and our members are so passionate about putting this lifesaving equipment in place.” Information has been provided to Stotfold Mill to help identify people who may have an underlying cardiac condition, prompting them to seek medical advice and obtain treatment to prevent cardiac arrest.

Life-saving defibrillator machines to be installed in every Asda store to help cut heart attack death toll

LIFE-SAVING defibrillator machines are to be placed in every Asda store, warehouse and office in the UK. The supermarket chain will provide 609 of the machines, which shock the heart back into life after cardiac arrest. The move follows an agreement between Asda and the British Heart Foundation.

The easy-to-use machines will be in place by the end of this year, and staff in every store will be trained in CPR. The aim of the scheme is to save more of the 60,000 people per year who suffer cardiac arrest out of hospital in the UK. At the moment, only a tenth of them survive, and every minute of delay cuts their chances by 10 per cent. Survival rates reach as high as 75 per cent when patients get the right care quickly enough. Dawn Clements of Asda said: “We’re really proud of our investment of more than £500,000 in life-saving defibrillators for all the communities we operate in. “The commitment we’re making could significantly cut the amount of time a cardiac arrest sufferer has to wait for CPR and defibrillation.” BHF chief executive Simon Gillespie said UK survival rates for cardiac arrest, which is not the same as a heart attack, were “astonishingly low” compared to countries with higher defibrillator use. He added: “Asda’s bold commitment really could mean the difference between life and death.”

Defibrillators save lives

Acting quickly when someone is in cardiac arrest and fighting for their life is crucially important.  Around 60,000 out-of-hospital cardiac arrests in the UK every year. When someone goes into cardiac arrest, every minute without CPR and defibrillation reduces their chances of survival by 10%.


A defibrillator is a machine that delivers an electric shock to the heart when someone is having a cardiac arrest. These machines can also be called AEDs (automated external defibrillators).
