Everyone is a potential emergency patient, and everyone is obligated to help in an emergency. Due to the rapid development of emergency medicine, the initial emergency efforts to save the life and health of the patient are increasingly being moved from hospitals to the streets and homes of those affected. Adverse external conditions, inadequate information about the patient, limited diagnostic options, and significant time pressure complicate decision-making. Ethical conflicts become particularly evident during resuscitation efforts: How can ethical principles be justified in emergency medicine? Is there a right to resuscitation, and what are the obligations of bystanders? How can the right to self-determination be taken into account in emergencies? This book provides answers.
