Purpose: In this paper, we intend to devise a plan to minimize the infection of medical staff through droplet particles generated from the patient’s respiratory by improving the location of the supply and exhaust ports in the negative pressure room. Method: To this end, the first improvement plan was analyzed through CFD simulation. Based on this, a final improvement plan was derived and the effect of improvement was evaluated by measuring and visualizing the concentration of droplet-like particles in a mock-up of a negative pressure room. Result: As a result of the final improvement plan being derived and evaluated, firstly, through visualization, in the ceiling air supply and exhaust condition, which is the existing plan, drop-like particles generated from the patient’s respiratory position diffuse to the respiratory position of the medical staff in a considerable amount, whereas in the ceiling supply and side exhaust conditions, which are the final improvement plan, most of the drop-like particles are transferred to the side exhaust port. It was confirmed with the naked eye that it quickly escaped and barely reached the respiratory position of the medical staff. In the case of the final improvement plan, compared to the existing plan, the concentration of droplet-like particles was reduced by 91% at the location near the respiratory of the medical staff and by 86% at the center of the room, confirming that it is a very effective plan to prevent the spread of respiratory infectious diseases to the medical staff.
