This book received support from the Faculty of Medicine of the National University of Colombia and the scientific Subdirectorate and the Department of Education of the Colombian Society of Anaesthesiology and Resuscitation (Sociedad Colombiana de Anestesiología y Reanimación S.C.A.R.E.). It is lucky to be blessed with the participation of young and enthusiastic academics from two public universities, the National University and the University of Caldas. We hope it will contribute to the study and practice of resuscitation in a country like Colombia, where health policies are underdeveloped and where, due to a lack of prevention, treatment is much more difficult. This is all the more the case in the worst of situations —cardiorespiratory arrest.
