15 minutes training enough to save lives with an automated external defibrillator

01.02.2005


Just fifteen minutes of training could make it possible for anyone to use a defibrillator to stop sudden cardiac arrest. A study published today in the journal Critical Care shows that a brief training session is all that is needed for safe and efficient use of an automated external defibrillator.

Sudden cardiac deaths affect nearly 400,000 people per year in Europe, and every day in the U.S. more than 1,200 people die from cardiac arrest before they reach hospital. In most cases, sudden cardiac arrest is due to ventricular fibrillation, a rapid, irregular twitching of the ventricles of the heart, which can be stopped by applying a defibrillator and delivering an electric shock within 1 minute of its onset. Automated external defibrillators are becoming increasingly common in airplanes, airports, companies, schools and other public places.

Stefan Beckers and colleagues from the University Hospital in Aachen, Germany, asked over two hundred first year medical students with no prior experience to use a defibrillator on a mannequin on two occasions, with a one-week interval between the sessions. Before the second session, the students attended a 15-minute talk on the purpose of the defibrillator, why it has to be used within the first minute of the arrest, and the importance of correct electrode pad positioning. Their response times were monitored during both sessions.



The study shows that 85.6% of the students could position the electrode pads correctly the first time that they tried. During the second session, the proportion increased to 92.8%. The time taken to apply the shock was 85 seconds during the first session, and decreased dramatically to around 59 seconds during the second.

The authors conclude that untrained laypersons are able to use automated external defibrillators quickly and safely. Their performance significantly improves after basic theoretical explanation of the device.

The reaction of untrained individuals to real emergency situations requiring the use of a defibrillator is likely to be different from their performance in simulated situations.

But the authors believe that their results are significant and should encourage basic training to prevent unnecessary sudden cardiac deaths. They add, "enhancing […] public information, for example via television campaigns or other extensive publicly available media, is of great importance."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
