Defibrillator is a medical device, which frequently allows to save a person’s life via electro pulse therapy in case of cardiac arrhythmias. The doctors consider that the main indication for using the instrument is ventricular fibrillation and arrhythmia. It is not always possible to bring the fibrillation to normal rhythm by cardiopulmonary resuscitation, and in such case, the defibrillator comes in handy. Nowadays, it is available in many public places, educational institutions, etc. According to statistics, from 12 to 16 pupils are having a cardiac arrest during their studies in just one year. It’s terrible even to think about the whole country. There are various kinds of modern defibrillators.
These types are of manual control and they are intended for specialists, who have the appropriate qualifications. Such instruments are equipped with various important functions, like synchronized cardio mode, monitoring and printing the observational results. The device is supplied with the screen that displays different parameters. The cardiac function is activated by the current discharge passing through the electrodes, attached to the patient’s chest. The monitoring and control is carried out by pressing the buttons on the panel.
Automatic cardiac defibrillators
Automatic defibrillators are mostly used in ambulances. Such types are designed specifically for emergency situations. These devices are easy to use and practically do not have much adjustments. You just need to turn on the device and attach the electrodes to the chest. The discharge is performed when simply pressing the button. Automatic cardiac defibrillators can independently choose the optimal current, perform the analysis of electrodiagram, control the repetition frequency of compressions and give the voice alerts. This automatic device is used not only by medical stuff, but in some cases even people who do not have special medical education are also able to work it out.
There is also a combined defibrillator, which is an effective combination of professional device and the automatic tool usability.
Implantable cardiac defibrillators
These unique types of defibrillators are designed specifically for implantation under the skin in the chest area. With the help of the thinnest electrodes, the internal defibrillator connects to the heart and sends the signals for correcting the heart rhythm once detecting the slightest problem. The implantable defibrillators can be used to alleviate the condition of a man, whose heart has regularly repeated disorders.
Portable cardiac defibrillators
The portable defibrillator is certainly not for “dummies”, but just for unskilled users of medical equipment. The trend “simplification of medical devices in favor of non-professional” has become very popular. What previously could be done only in doctor’s office is driven out of hospitals and becomes available for ordinary people. Due to the portable defibrillator, the simple man can help a person who has a cardiac arrest. Today, the developed countries are having a whole campaign on training civilians the emergency medicine techniques, and as a consequence – the campaign on production of life-saving devices for users with no medical education. And the portable defibrillator is a step towards the implementation of this program.
Cardiac Science defibrillators G3
In 2001, Cardiac Science (USA) acquired the Survivalink Corporation, which had been producing portable automatic external defibrillators (AEDs).
The logical, cardiac science defibrillators of PowerHeartAED series allow anyone to quickly and efficiently perform the defibrillation in case of a sudden cardiac arrest, which reduces the possibility of a tragic outcome. Today, the Cardiac Science company offers 3 models of portable defibrillators of the G3 series, which are distinguished by their capabilities and cost, but have several common advantages: portability (27X8X31 sm, less than 3.2 kg), self-testing, defining the indications for defibrillation, phase patented form of discharge STAR, powerful lithium batteries, clear voice instructions, battery indicator and the ability to perform defibrillation for kids under 8 years.
All devices of G3 series are intended for restoration of the heart rhythm in case of life-threating arrhythmias, through a biphasic electrical discharge.
