This revised edition provides photographically illustrated step-by-step guidance for all conditions and first aid treatment, brought in line with the upgraded standards of the European Resuscitation Council. It provides at-a-glance, life-saving action plans for all emergency situations. To help explain why and how first-aid techniques work, greater emphasis has been placed on how we are structured (anatomy) and how we function (physiology). A clearer understanding of what is normal should help you to decide what may be wrong or abnormal and enable you to provide the correct treatment.
