Diseases of the respiratory system, including Covid 19, lead to respiratory disorders, which affect the quality of life and performance of the patient. Studying the factors that have negative consequences for breathing is an opportunity to achieve control over these factors, as well as take timely measures to prevent complications.
The aim of the present study is to establish the influence of certain factors, such as occupational risks, smoking, coronavirus infection on the normal function of the respiratory system in health professionals from the health care system.
Material and methods: A survey of 200 health care professionals from medical institutions in Sofia in 2021-2022 was conducted.
Results and conclusions: According to half of the respondents in the working environment of medical institutions, there are occupational hazards that have a negative impact on the functioning of the respiratory system. The results show that 78.00% of respondents have suffered from Covid 19, with 1/3 of them indicating that they have serious lung damage after suffering from the new viral infection. The health of healthcare professionals is essential to ensure the quality of healthcare for patients in hospital care.
