“Your hands can save lives”: this was the slogan of the "http://www.restartaheart.eu/" European Restart a Heart Day, organized by the European Resuscitation Council on October 16th. Researchers from the Shock, Organ Dysfunction & Resuscitation group (CRIPS) and the Clinical Research/Innovation in Pneumonia & Sepsis group (SODIR) at Vall d’Hebron Institute of Research (VHIR) participated in this awareness day, explaining their experience in training school children in bystander cardiopulmonary resuscitation (CPR). Since 2007, they have educated over 300 students from the Sant Feliu School in Cabrera de Mar (Barcelona) about how to give this vital assistance.These initiatives have been extended to all the society, especially in the heath sector, with the aim to improve the very low numbers of people surviving out-of-hospital cardiac arrests. Nowadays CPR is delivered in only 1 in 5 out-of-hospital cardiac arrest, and it is estimated that 10 people die every day in Catalonia because of a cardiac arrest caused by an alteration of the heart rate usually due to an acute myocardial infarction. In these situations, if CPR is not administered quickly, death can occur in just a few minutes. Otherwise, with RCP techniques, the survival rate after suffering a cardiac arrest, which in Europe is just the 10%, could be tripled, so many deaths could be effectively prevented.
