Introduction: Asthma is a disease characterized by a chronic inflammation of the airways and consequently a heightened responsiveness to different stimuli. The airways are narrow due to the inflammation. It is essential to change one's lifestyle when managing asthma. The classic therapeutic models are becoming less important because of the increase of the disease; prevention and health education are making it to the forefront. Children, adolescents and their parents need to be included. A nurse has a significant role in health education. The continuous execution of the health education and knowledge testing as well as its effect on managing the disease is very important, which consequently influences the quality of life. Goal: The goal of the dissertation is to present and describe asthma. To research it in detail and to show the effect of asthma on the quality of a child's life by reading the technical articles. Methods: Descriptive method is used in the dissertation, which includes domestic and foreign literature published between 2003 and 2006, focusing on the last five years in the field of children's asthma and the life quality of a child who has asthma. The literature overview was done in the period between June and December 2016. Discussion and conclusion: During the analysis and the critical reading of the technical articles, we discovered that the factors that cause asthma are strongly connected and dependent on each other; that is why, the causes for the emergence of asthma are difficult to determine. The main issue is a late diagnosis of the disease when all signs are evident in a child. This consequently leads to a late treatment and a worse quality of a child's life. Health education for children with asthma and their parents is crucial for a successful prevention of asthma getting worse; it betters the health state of a child, it consequently reduces the number of doctor's visits, and it improves their quality of life.
