Changes In The History Of Automated External Defibrillator
by Tom Says
The history of automated external defibrillator has generated success stories in the revival of patients suffering from cardiac arrhythmias of the ventricular fibrillation and ventricular tachycardia. The automated external defibrillator has shown its essential purpose in saving thousands of lives in the past few decades. Since the automated external defibrillator's development in the 1940's, the AED has had major technical modifications and changes in accessibility.
Improvements in the History of Automated External Defibrillator
The earlier development of the AED involved the usage of an alternating current. Its first application on a person was in 1947, where results were successful. The AED was then improved for closed chest defibrillation in which electrodes were delivered to the chest wall of animals in laboratories. New findings were then used to apply the external defibrillation on a human, which turned out to be successful.
Later in the history of automated external defibrillator three more types of defibrillators were invented alongside CPR methods. All three devices used the alternating current technique and needed direct performance on the heart. This method was later found to be too intrusive.
It was therefore time to develop defibrillators that did not require open chest surgery. This was when the closed chest direct current defibrillator was invented. The new device was known to be highly effective and reduced side effects. It worked by delivering electrodes externally. Other AED designs were made to cater to both internal and external conductions.
Changes in Accessibility in the History of Automated External Defibrillator
The changes made in accessibility have been an essential part of the history of automated external defibrillator. At first, scientists and researchers were the only ones who were using the AED in their attempts to restore healthy heart rhythm in patients. It was a time when power utility workers, who were most susceptible to ventricular fibrillation, needed the research to aid in sudden cardiac arrest.
Later designs of the AED then found their way to hospitals. AEDs were accessible only to medical personnel and paramedics. During this time, the common scenario was paramedic staff attempting to revive the patient with the device while rushing to the hospital in an ambulance.
Nowadays AEDs are highly accessible in most public places including healthcare, government, educational and recreational establishments. Locations frequented by more individuals with higher risks of cardiac arrest such as males over 50 call for accessible AEDs. The availability of AED in these places is considered crucial.
In the modern day AEDs can be easily purchased and placed in the home. This has given relief to patients who are staying at home and are not located in hospitals. Then again, some medical specialists are concerned over the unprofessional use of AED on patients.
In the beginning of the history of automated external defibrillator, the thought of using defibrillation at home seemed vague. But since its introduction to public environments a growing number of individuals have embraced the idea of the home use of defibrillators. The devices are now accessible in both medical and commercial institutions.
