THE DISTANCE COVERED BY A DEFIBRILLATOR


When a 999 call is made, the distance from the patient to the defibrillator may determine whether the defibrillator is deployed to the rescue.

This is called the Activation Radius. Different ambulance services have different activation radii for community defibrillators, and they also have different methods of operation for these schemes. To try to explain this, we have highlighted the key differences between services.

When a 999 call is made, the ambulance service control room will triage (assess) the situation and if appropriate, request the community defibrillator be collected. 

In most services, they will tell you the location of the nearest defibrillator, and give you the access code if appropriate (not all public defibrillators are in locked cabinets). If you are the lone rescuer with the patient, most services will not ask you to collect the defibrillator, but ask you to stay with the patient and undertake Chest Compressions to keep the patient alive. 

CHT has the VETS system in operation to help in situations where there is a single rescuer, and/or a spread out community. 


The current activation radii are listed below (and are subject to change). These radii may mean you will need to plan your placement of defibrillators, or consider other methods of activation.

Ambulance services are also covered by Ambulance Quality Indicators. This is the mechanism for monitoring performance. 

To comply with the 2017 AQI guidance set by the NHS, the ambulance service cannot record a community defibrillator as counting to the 8-minute Category 1 call target unless the defibrillator is on scene, and the operator has confirmed that the person present is willing to use this if required. 

CAT1 calls are heart problems. Under the AQI2017, they can also count the CAT2 calls (stroke, other life-threatening) as meeting an 8-minute response if similarly the defibrillator is on scene and the person attending confirms by positive agreement they are willing to use if required. These AQI may change in the future. 

By attending both CAT1 and CAT2 calls, this may result in your community defibrillator being deployed quite frequently.

Please make sure you have read and understood this disclaimer - It will be assumed that you have read prior to CHT receiving any request. CHT are not responsible for your fund raising, nor your cPAD operations, but may assist in both. CHTs only aim is to support the installation of a cPAD scheme in the most cost effective way possible adhering to Best Practice, and help save lives in your community. This website, and any downloaded information, is for information only on how to go about obtaining and installing a cPAD, and other relevant information. All copyrights and trademarks are recognised. All support for the cPAD will be undertaken by the village committee responsible and via standard manufacturers warranties. Any training organisation will only be responsible for the initial awareness training and not for the functioning or maintenance of the AED. Please do not send any monies to CHT until you have registered your scheme with us, and have agreement from the local ambulance service for the establishment of a cPAD scheme. All schemes must be registered with the local ambulance service (CHT will also undertake this or you can do via this site, but this does not remove responsibility for you to notify the local ambulance service of your AED location). 999/112 (ambulance) must always be called prior to using a cPAD equipment. VAT may be applicable if your organisation is not an eligible body as defined by HMRC. All current or historical claims for VAT will be met by the local community. All schemes will be asked to sign an agreement taking responsibility for their own fund raising and donations to CHT, and then the operation and maintenance of the cPAD equipment. All CHT provided schemes will need to manage their maintenance through the WebNoS online system as a condition of CHT support. It is your responsibility to maintain the equipment in working order and to make sure the local ambulance service is aware of this. WebNoS makes this possible and also acts as an audit trail for management of the equipment. Sites provided by CHT and not using WebNoS may be disengaged from the ambulance service CAD systems. Any web site showing defibrillator locations is for information only, and should not be used in preference to dialling 999. CHT works in close cooperation with the UK ambulance services. Always dial 999 in an emergency
