Intensive care medicine is a branch of medicine that deals with the treatment of critically ill people, providing them with supervision, care, treatment and organ system support. It is carried out in intensive care units by specially trained medical workers who not only have machinery for continuous monitoring of critically ill patients, but also have technologies and knowledge for maintaining the lives of patients who are there. Despite the coordination between medical staff , their knowledge and the technologies used, up to 15-20% of people in ICUs end their lives there. Concerning patients who have reached the terminal stage of their illness, most invasive and intensive procedures do not bring any progress in the healing process. For this reason, in order to prevent inappropriate treatment, a new approach, end of life practice ( EOL practice) has emerged in ICUs for people who are at the end of their lives. Not only does it include the patients and their families in the process of decision making, but it also concerns the making of medical decisions regarding procedures that should be further implemented or corrected. Each patient is seen as an individual human being, and according to The Codex of Medical Ethics and Deontology, it is necessary to respect the basic principles of autonomy, beneficence, nonmaleficence and distributive justice.
