AED guide

The defibrillator is used to analyze the electrical activity of the heart. If it identifies ventricular fibrillation or tachycardia, the device is charged for the shock. In the semi-automatic model, the device will ask the rescuer to press the shock button; In the automatic model, the machine autonomously proceeds to discharge after giving an audible warning. The rescuer, in both cases, makes sure that no one touches the patient.




Essential features


The AED must automatically detect as many defibrillable arrhythmias as possible (only 4 in the world do this and RESCUE SAM is one of them).

The AED must be intuitive and the commands issued must be clear to best support the rescuer.

The AED must be provided with all the certifications and requirements required for electro-medical devices.

The company must guarantee the product also in the following years with maintenance plans and software updates.

The optimal features of the defibrillator



A national manufacturer also offers solidity and quality in service; If it is reliable, it guarantees continuity of service, since the defibrillator has an average life of more than 10 years. It is easier to run into problems with unknown devices, without a historicity or an established reputation.



Very important are the certifications, the AED must have obtained the EEC Mark, compliance with IEC 60601 and IEC 60601 1-2-4 safety standards and the manufacturer/distributor must be ISO certified.



Buying a low-cost AED means buying a life-saving device with dubious quality that has no guarantees or support during after-sales. In addition, the initial savings involve extra costs for spare parts and maintenance over the life of the AED; so the time will take away the convenience.



The advanced, best and above all most useful defibrillators are those that have a possibility of combined use for adults and children. There are proposals on the market with only adult configurations or only pediatric configurations, which should be chosen only in specific situations.



We advise you not to buy defibrillators whose Protection Index is unknown or of which only a part is known, as you will not be able to be sure of their effective level of protection against dust and liquids.



The biphasic wave allows the defibrillator to handle greater impedance ranges, offering the best existing performances: the best life-saving therapy with fewer side effects for heart cells. The algorithms also allow continuous analysis even during the charge of the shock.



A compact and lightweight AED can be easily transported in an emergency.



The AED should be intuitive, easy to use, with clear voices and images that can guide you in case of use.



Batteries, electrodes and software must be periodically updated and the annual cost may vary; Excessively cheap AEDs end up with problems soon. In addition, the initial savings result in the end in spare parts with a shorter life. The initial convenience is thus lost with the passage of time.



Does the AED have a periodic self-test system? Does it have a software? Can the defibrillator be maintained without problems for a long time? The device may need to be updated, manually or independently via USB cable and manufacturer’s software.

Further tips


The only necessary controls are:

· Replace any used, damaged or expired accessories

· Check that the outside and case of the defibrillator are not damaged

· Check that the indicator that marks that the defibrillator is working properly

Some defibrillators perform an automatic test to verify the device and keep it ready for use: this procedure optimizes the periodic checks performed in person. In case of malfunction, the device signals a lack of readiness. It is increasingly common to activate remote control services for defibrillators, which allow you to check deadlines, operating status, position and use.


It is good to know that each defibrillator has characteristics that must be preserved over the years.

The AED is in fact powered by a long-lasting non-rechargeable battery, which can be guaranteed by the manufacturer between 4 and 7 years. Currently the most reliable ones on the market have an average life of 5 years, but their operation can be compromised by an accidental drop or improper storage conditions. However, each medical device has a series of alarms in case of malfunction: when these occur, the machine promptly signals the problem.


Together with the battery, there are electrodes, or the “pads” that are applied to the chest of the person to deliver the shock. The electrodes have an expiration date and must be replaced after each use, or after 24 months.


The AED may have updates in case of changes to the Guidelines on the use of defibrillators. Depending on the company or retailer, the upgrade may be offered by a technician. A defibrillator is not a device to be forgotten in a corner; the device must remain visible so that its status can be checked.


Beware of the possible deception of a low price of consumables and consider their durability. Low-quality consumables may be compatible but result in shorter lifespan. In a worst-case scenario, they may not work properly at the time of use. A factor to consider is that, according to the regulations on medical devices, if the compatible component is not reported and authorized by the manufacturer, this affects the warranty of the device.

Protection for who protects you

Nel caso in cui si decida di posizionare il defibrillatore all’aperto ci si deve munire di una teca in cui posizionare il proprio DAE. I defibrillatori infatti sono apparecchi elettrici che potrebbe non funzionare correttamente se esposti a temperature sotto lo 0° o sopra i 50°. Se la destinazione del defibrillatore è all’esterno è necessario proteggere il DAE con una teca dotata di termostato per regolare la temperatura che, oltre dall’acqua e dalla polvere, lo protegge dagli sbalzi termici. Inoltre se si temono atti di vandalismo o furti si può usufruire di teche dotate di sportello allarmato, il quale suonerà nel momento in cui viene aperto.

Spesso i comuni posizionano il defibrillatore all’esterno di farmacie, uffici, nei pressi di monumenti, piazze o parchi. Le società sportive invece possono posizionare il DAE nei pressi del campo di allenamento, vicino a una piscina oppure sotto una tettoia. Le associazioni di soccorso si trovano spesso a soccorrere in diverse condizioni meteorologiche e di campo; gli stabilimenti
balneari invece usano e posizionano il defibrillatore nelle immediate vicinanze della spiaggia e del bagnasciuga.

Città cardio protette
grazie al DAE


Circa un terzo degli arresti cardiaci si verifica nei luoghi pubblici e spesso avere un DAE nelle vicinanze è un elemento cruciale per intervenire entro dieci minuti dall’accaduto. Il Comune è un’istituzione che può farsi promotrice di un progetto di defibrillazione precoce sul territorio, anche in cooperazione con le realtà locali (associazioni, enti pubblici e privati...) per rendere i suoi cittadini veramente cardioprotetti.
