Assessing exposure to bioaerosols during bronchoscopy operations in hospital settings


This project addresses the problem of exposure of hospital personnel who are required perform bronchoscopy procedures. During such procedures, a multitude of aerosols originate from the patient’s mouth and nose. The aerosols contain microorganisms, some of which may be pathogenic and may end up suspended in the surrounding air.
The main objective of this research project is to determine the total concentration of bioaerosols during bronchoscopies and suggest preventive or corrective measures. Measurement of total bioaerosol concentrations will be carried out in two bronchoscopy rooms: one located in an outdated facility and the other in a modern facility that complies with the recommendations of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Various ventilation parameters and ergonomic layout factors will also be evaluated in order to assess their influence on measured bioaerosol concentrations. Based on the results obtained from modelling, an optimal layout may be proposed.
The project will make it possible to focus on the appropriate interventions for maintaining bioaerosol concentrations at acceptable levels and to formulate recommendations that will facilitate adequate management of this occupational hazard in bronchoscopy rooms.
