Characteristics and types of defibrillators in Spain

All types of defibrillators that exist and their applications

Types of defibrillator

What types of defibrillators are there?

 

Several types of defibrillators, and all of them have in common that they are devices capable of restoring the normal heart rhythm of a person who has suffered sudden cardiac arrest or a harmful arrhythmia.

Within a generic classification, two defibrillator categories.

  • The external defibrillators They are those that can be installed in any public or private area so that they can be used in the event of a possible sudden cardiorespiratory arrest. Within external defibrillators, there are 3 types of defibrillators, automatic, semiautomatic and manual.
  • The internal defibrillators, are subcutaneously implantable defibrillators by surgery, which introduce the electrodes directly into the heart chamber in patients with arrhythmias or other cardiac pathologies.

 

Types of external and internal defibrillators

 

Currently there are 5 types of defibrillators grouped into two aforementioned categories, pointing out that external defibrillators are designed to be used by people without/with knowledge of first aid, and manual and internal implantable defibrillators, which are only for use by health personnel in hospitals or medicalized ambulances.

The types of defibrillators are:

  1. AED automated external defibrillators (cardioprotection)
  2. DESA semi-automatic external defibrillators (cardioprotection)
  3. Vest external defibrillators (cardioprotection)
  4. Implantable Automatic Internal Defibrillators ICD (Single Chamber Defibrillator)
  5. Manual external defibrillators (hospital defibrillator)

Automated External Defibrillators (AEDs)

 

The automated external defibrillators (AEDs) They are the equipment installed in cardioprotected spaces, they have the function of applying shocks automatically without any intervention on the part of the rescuer, except for the placement of the electrode patches and performing chest compressions.

The AED defibrillator is capable of analyzing the heart's rhythm and delivering a shock only if necessary. These automatic teams guide with clear indications of what to do step by step, an aid to rescuers without / with experience in CPR resuscitation techniques.

 

type of automatic external defibrillator AED

 

AED automatic external defibrillators are intelligent electromedical equipment, which through visual signals and voice prompts give instructions to the rescuer during a cardiorespiratory arrest.

The AED defibrillator is capable of administering the necessary shocks with which to restore heart rhythm, keeping in mind the importance of correctly perform CPR chest compressions.

These DEA devices can be found in cardioprotected spaces just like DESA defibrillators, with the only difference between them being the fact that the discharge button is pressed or that the defibrillator applies the defibrillation discharge without any intervention by the rescuer.

Semi-Automated External Defibrillators (ASEDs)

 

The DESA semiautomatic external defibrillators They are electro-medical devices capable of reversing cardiac arrest, just like AED defibrillators, these defibrillators are for public and private use.

These are semi-automatic devices that warn at the time of shock and indicate to the rescuer that they must separate from the patient and press the shock button that will activate defibrillation.

Semiautomatic external defibrillators are devices that require little training on the part of the user, since the device indicates the steps to follow, although at Neosalus we always recommend prior training in CPR with which to effectively deal with a medical emergency situation due to arrest cardiopulmonary.

These electromedical equipment incorporate the help of health personnel specialized in medical emergencies through an automatic call device to the telephone 112. These DESA defibrillators for cardioprotected spaces They are the most common to find in public places such as shopping centers, airports, companies, houses, communities, transport, theaters, hotels, campsites, cars, schools, etc.

 

DESA semiautomatic external defibrillators

 

External defibrillators for cardioprotected spaces required in some autonomous communities, consult the regulations on defibrillators in your autonomous community.

 

Portable vest external defibrillators

 

Vest defibrillators are external cardioprotection equipment, which do not require any action on the part of any person to administer an electric shock to the heart, these portable defibrillator equipment are automatic and personal.

These external defibrillators by means of the electrode patches adjusted in contact with the person's body, monitor the heart by analyzing the heart rhythm, and if necessary provide an electric shock, these defibrillators are suitable for use in people at risk of suffering an arrest sudden cardiac arrest

 

Hospital manual defibrillators

 

The manual external defibrillators They are intended for use by qualified health personnel because their functions are much more complex. According to European regulations, it can only be used by trained healthcare personnel.

 

Manual external defibrillators

 

Hospital manual defibrillators are also used in heart operations, they have blades for quick and easy open-heart placement. The electric shock is done manually directly to the heart.

implantable internal defibrillators

 

The implantable internal defibrillators They are devices installed subcutaneously, with electrodes installed inside the heart chamber through which they perform a direct electrical discharge with which to stop or reverse the chaotic rhythm of the heart at the precise moment when an arrhythmia or cardiac arrest is taking place. . This type of defibrillator is indicated to treat arrhythmias generally called ventricular arrhythmias.

Internal defibrillators monitor heart rhythm abnormalities and act automatically by applying a strong, sudden electric shock that contains enough energy for the arrhythmia to subside and the heart to resume its normal rhythm.

 

ICD automated internal defibrillator

 

A surgical operation is required to subcutaneously implant these internal cardioprotection equipment, these defibrillators are implanted by cardiology specialists.

 

Types of defibrillator by type of electric shock

 

Within the different types of defibrillators that we can find, there is also a classification based on their electric discharge, that is, according to the power or current with which the electric shock is applied.

In this categorization of defibrillators based on their electrical discharge capacity, we would only find two types of defibrillators, monophasic and biphasic equipment.

Monophasic defibrillator type

 

The monophasic defibrillators They are characterized because they only have a directional electric current which is carried out in only one direction. These monophasic defibrillators can deliver electrical shocks of 200, 300, and 360 joules.

Biphasic defibrillator type

 

The biphasic defibrillators They have a much more advanced system which requires up to 40% less energy to defibrillate and consequently produces less damage.

These apply a current in both directions, since they are capable of changing polarity during the shock. Biphasic defibrillators are capable of delivering three 150 joule shocks. They are the most efficient equipment with a lower energy expenditure, they can apply a higher number of discharges.

La cardioprotection it can be personal or collective, it can be carried both internally and disposed of externally. Some to deal with sudden death and others to treat arrhythmias and cardiac pathologies. Now you know all the types of defibrillators that exist and what their characteristics are.
