Method: An experimental study conducted from June 2022 to August 2024 in the ICU. Samples were collected from the central air conditioning system (AHU), air outlets, and patient rooms. Results: The UVC system significantly reduced the concentration of microorganisms in the air and on surfaces. In the AHU, the percentage of pathogenic bacteria decreased from 40% to 16.7% after six months. The concentration of bacteria in the air at the air outlet decreased from 144 CFU/m³ to 62 CFU/m³ after 60 days. In patient rooms, the rate of cultures with pathogenic bacteria decreased from 41.3% to 15.2%. Conclusion: The UVC system is effective in reducing microorganisms in the air and on surfaces in the ICU. However, it is necessary to combine this system with other infection control measures for optimal effectiveness.
