Sneak Preview: Physio Control Lifepak CR2

Today seen at the Emergency Services Show in Birmingham and from tomorrow on show at the ERC conference in Reykjavik; the new Physio Control Lifepak CR2 AED. The latest addition to Physio Controls impressive line of AEDs. Physio Control is awaiting CE approval, then the big distribution of this public defibrillator, making it available to a larger audience.

We watched the demonstration of the CR2 and can inform you that the AED is practically the same as it’s predecessor, the main change being the colour. It is compact, with a white plastic lid and a black carry-handle. The status indicator displays a bright green flashing light, visible at the front of the AED. The device starts directly on opening and the electrodes are released by pulling on the clearly visible red handle. The shock electrodes are firmly attached to the AED by a tape. On opening the AED, you see four buttons: a language selection button, the on/off button, a child resuscitation button and finally, a shock button.

Currently only available as a semi-automatic, there will be a fully-automatic available. The price of the CR2 is not yet known, but is expected to be slightly above its predecessor the CRplus.

The Lifepak CR2 comes with an 8 year warranty. The battery and shock electrodes have a 4 year shelf-life before they require replacing. The water and dust resistance is set at IP55 which means the AED can compete with the best. Voice prompts from the Lifepak CR2 are quite extensive compared to other AEDs: it vocally announces the depth of chest compression as an aid to the rescuer. The shock protocol is the same as the other Lifepak AEDs, up to a maximum of 360 Joules.

Physio Control has developed an app simultaneously with the release of the Lifepak CR2, aimed at helping to manage AEDs. This app, which can be used in a range of browsers, allows an organization, different AEDs can monitor easily. The CR2 Lifepak AEDs can be connected to the database via Wi-Fi or mobile data (optional), whereby an alert can be sent when an AED is removed, opened or when an audit is needed.

Facts concerning CPR and AEDs in General

Every year, nearly 600.000 people die from heart diseases so, nowadays, everyone should be aware of how to act in emergency situations. Underneath, some facts about CPR as well as AEDs are presented:

  1. ­­CPR does not restart a heart. Rather, it physically pumps blood through the heart and empowers oxygen to reach the brain. This is totally imperative for someone encountering heart failure. It is stated, that if CPR is regulated instantly, it doubles or even triples the casualty’s rate of survival.
  2. Both CPR and AEDs are sheltered. It is certain, that a person cannot hurt someone by doing mouth-to-mouth.
  3. An AED will regulate a stun for two sorts of unusual heart rhythms: ventricular tachycardia and ventricular fibrillation.
  4. AEDs are so natural and easy to use, that even a third-grader can utilize one – literally. An AED will guide you through every stride as well as figure out if a stun is required. It is that simple!
  5. The survival rate for sudden cardiac arrest (SCA) is under 5%. This is because of restricted AED approachability.
  6. For consistently that goes without defibrillation, survival diminishes by 7-10%.
  7. Sudden cardiac arrest happens frequently in the home (57%-75%), which majority of times are unequipped with an AED.
  8. An AED electrodes gather data about the heart’s rhythm and convey the stun for the AED.

Poor maintenance makes AED defibrillators unreliable

maintenance-01Heart-defibrillator maintenance leaves much to be desired. The largest suppliers of resuscitation-devices have issued a warning. Last Tuesday a woman in Bergen op Zoom in the Netherlands narrowly escaped death when an AED failed.

High costs and ignorance are the cause of many Automated External Defibrillators being poorly maintained. Owners install a lifesaving shock device in their home, but they forget about it, observes one of the country’s largest suppliers, Medisol.

The reasoning usually behind this is that customers, having just spent on average £ 1,000,=, feel secure. “This however will not be of much help in the event of a life-threatening heart event.”, notes Anne-Marieke Wieman of Medisol.

Free inspection

Medisol held a campaign a year ago to inspect their customers’ totally free of charge. About half of the devices inspected displayed some defect. Often the defibrillation pads had ceased to operate (lifetime: 2 years) or the batteries were depleted (lifetime: four years). The cause is often lack of awareness, but high maintenance costs also contribute to customers’ unwillingness to pay. “The annual fee for a maintenance service contract varies from £ 59 to 99 per annum. Only 50 procent of Medisol’s customers conclude such a contract, generally the least expensive”. 

Excessive exposure to moisture

maintenance-02With the risk that victims cannot be helped quickly enough. This happened last Tuesday while a woman was in cardiac arrest in a shopping centre in the Dutch city Bergen op Zoom. A nurse who was at the scene proceeded with CPR and shop employees rushed to a community centre to collect an AED defibrillator. In the meantime the police had arrived and had taken over the resuscitation, but couldn’t get the AED to operate. It transpired later that the AED had been installed at a location where it was exposed to excess moisture.
Despite this the woman survived and is still in hospital. Her son Michel Wiegeraad finds  it “ridiculous” that the AED defibrillator couldn’t do its job. “Such a thing should just work. AED’s should really have a label like fire extinguishers do. They should also be subject to mandatory annual inspection. This ended on a happy note, but if my mother had died, I’d have lived on with the question: What would have happened if that AED defibrillator had simply worked “?

The Inspection of the Healthcare Council had already in 2013 raised the alarm after receiving several reports from suppliers on failing AED’s. In all instances the electrical stimulus needed had failed to materialize “with in some cases fatal consequences for the patient.” On that occasion the Council asked manufacturers to send a letter to the users drawing their attention to the need for preventive maintenance.


The owner – many individuals like shopkeepers and sports club owners – is responsible for maintenance and replacement of parts. If the battery needs to be replaced, most devices will beep or a led-light will blink. But you will hardly notice that if you store the AED defibrillator in a carrier case in a place where only a few people come.’

The Medisol Service Centre

The Medisol Service Centre can offer you two kinds of maintenance service to ensure that your defibrillator is always ready for use.
The Standard Service guarantees continuity. If the AED has been deployed, has a malfunction or has been stolen, a rental-AED will be supplied within 24 hours and we shall ensure that your AED is once again in service at very short notice.

The Extra Service guarantees, as well as continuity, an annual inspection of your AED accompanied by a certificate of approval. This latter confirms that your AED is being properly maintaind. The maintenance is carried out according to the standards of the European Defibrillator Certification Institute. For more information please refer to The service provided is intended for companies that have an AED available as part of their emergency services.

Standard Service
We shall inform you in good time when your AED needs new batteries and electrode pads. You will also be informed  when the manufacturer issues a software update for your AED.

24/7 phone access for reporting a malfunction, emergency use of  the AED and theft of your AED.  When reported before 16:00 hours during working days, you will receive a rental-AED the following day and your AED will be collected.


Our Standard Service is as follows;

  • After deployment of the AED:

         Adaption of your AED, replacement of batteries and electrode pads

         Reading out of ECG data

         Evaluating proper functioning of the AED

Biggest Basic Life Support change in ERC guidelines 2015: the role of the emergency response communication centre


Not much has changed for Basic Life support in the new ERC 2015 guidelines. But small changes can make a big difference for a person’s life. So today at the ERC congress in Prague, one of the main subjects was about the role of the Emergency Response communication Centre.

A fast response and early CPR increase patients survival chances and therefor the bystander CPR has a huge lifesaving potential. In Europe, there are major differences in the way people act when they find a person lying on the ground and presumably dead. Not everyone is used to consider the possibility the victim might survive when CPR is started fast.

It all starts with recognising abnormal breathing. Any person that is unconscious and not breathing normally, is in direct need of CPR. As soon as the abnormal breathing is diagnosed, emergency services should be called to make sure professional help is on its way.  A lay person should get it’s instructions from the emergency dispatcher. How to get the bystander to perform good CPR?


New 2015 CPR guidelines, what are matching BLS products?

With the changes of the CPR guidelines that have been published in October, the European Resuscitation Council emphasises the importance of feedback during training. Quality improvements in Basic Life Support training can be accomplished by training with an advanced manikin with feedback. In real life situations, an AED with extensive guidance and feedback is recommended.

What products meet up to these recommendations?

For the manikins, the more feedback the better. Good measurement and feedback will benefit the fine-tuning of the students skills. Currently, one of the best adult manikins in terms of feedback possibilities is the Laerdal Resusci Anne QCPR (combined with a Skillguide or even better with the Simpad Skillreporter). If you have a small budget but still want the look and feel of an advanced manikin, the Ambu Man I or W can be a smart choices. Of all the basic manikins under €250,-, the Prestan manikin scores best on feedback. Ambu Uniman Sam and Laerdal Little Anne have basic measurement. For paediatric CPR instructions with feedback you need the Laerdal Resusci Baby QCPR or the basic Prestan Baby.

There are a number of AED’s that have feedback build in. The Heartsine Samaritan PAD 500P, Cardiac Science Powerheart G5 and Zoll AED Plus measure the depth of the chest compressions and suggest improvements during the CPR process. Adapted audio and visual instructions help improve the patients survival chances by instructions to improve chest compressions. If you want extended CPR guidance, but you are not interested in feedback, then the Philips public AED’s are among the best. These AED’s have an information button that can be pressed if the rescuer needs more instructions. If he does not need it, the Philips Heartstart HS-1 and FRx AEDs are quiet and leave you concentrated on lifesaving.

Medisol/AEDexpert will be in Prague for the ERC congress Resuscitation 2015 from the 29th until the 31ste of October. This particular ERC congress is important because the new CPR reanimation guidelines for the next 5 years will be presented here. This could also be the moment to meet up with business associates to expand collaboration. Especially now, when the eyes of the AED world are all focused on Prague.

Will you be there? We are looking forward in meeting you. If you wish to make an appointment, please contact Customer Service, phone number + 44 (0) 1223-790124.

We’ll keep you posted on this page.

The differences between the various Zoll electrode pads

These pads are suitable for the Zoll AED Plus and the Zoll AED Pro. Which ones should you choose?  In the overview below we have set out the differences that may help to make your choice easier.

Click here to view the Zoll electrode pads in our web shop.
 As you can see there are 4 types. All of these electrode pads can be used with the Zoll AED Plus and the Zoll AED Pro and are interchangeable with the professional monitors/ defibrillators from Zoll that are used by ambulance services. All these sets can be used once only. After they have been removed from their sealed package they must be used straightaway.  Electrode pads have a limited shelf life because the conductivity of the adhesive gel that will decrease with time.

Zoll CPR/D Padz (are.8900-0800-01)
These pads are the preferred pads for the Zoll AEDs as they have been developed for maximum  convenience. Each pad has been made from one piece, which makes accurate positioning easier. These pads have a sensor that measure the depth of the chest compressions. The AED responds to these measurements by giving extra instructions such as ‘press harder’. Better chest compressions will help to increase the chances of survival. The CPR/D pads have a 5 years shelf life. This explains the higher purchase price compared to the other Zoll electrode pads. These electrode pads are  intended for adults.

Zoll CPR Stat Padz (art.8900-0400)
The CPR Stat Padz are not made out of one piece like the CPR/D pads, but are provided with a sensor. These pads are made for the aid worker who welcomes extra instructions but not one-piece pads. These electrodes may also prove advantageous when the AED is used regularly. Their price is lower, all functionality is preserved and their shorter shelf life (about 2 years) is less important. These sets are intended for adult uses.

Stat Padz II (art. 8900-0801-01 Zoll)
Stat Padz are sold widely to people who have no interest in the CPR-feedback of the Zoll AEDs; no sensor is attached to the pads and there is no feedback. This product is made for the very CPR experienced aid worker who would not benefit much from CPR feedback. The electrodes are only connected to each other through a cable and are therefore not made out of one piece. These are the most favourably priced electrode pads and have a shelf life of approximately two years.

Zoll Pedi Padz (art. 8900-0810-01)
The Pedi Padz are intended for children up to 8 years of age or about 25 kg of body weight.

These electrodes guide the energy level of the shock downwards in order to provide optimum therapeutic benefit to smaller bodies.  It is good practice to keep paediatric pads in the vicinity of the AED when it is kept  in a place where many children are present.

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).
