Chemical and bacterial air pollution in hospital rooms with different air exchange

Abstract

The quality of the air environment in hospital rooms has a significant impact on epidemiological safety and the general condition of patients. This paper examines the features of chemical and bacterial air pollution in various modes of air exchange in medical institutions. A comparative analysis of the level of microbial contamination and the concentration of harmful chemicals (volatile organic compounds, disinfectants, etc.) during natural and mechanical ventilation was carried out. Factors contributing to air pollution are considered, including the density of patient accommodation, the frequency of ventilation, and the intensity of detergent and disinfectant use. The work emphasizes the importance of optimizing ventilation systems and monitoring the air environment to reduce the risk of nosocomial infections and improve sanitary and hygienic conditions.
