Case Study of Ventilation Performance in a General Hospital Examination Room Based on Carbon Dioxide Concentration Measurement
Year: 2021
Type: article
Abstract: A general hospital examination room with the same ventilation method as a patient cluster occurrence of COVID-19 was measured to clarify its ventilation performance. The only ventilation to the room was the air from the corridor through the undercut of the door. It was found that, for each measurement point, the highest indoor carbon dioxide concentration was approximately 1200 ppm, which was 400 ppm higher than the air supply. If the number of people in the room is large, it is possible that the ventilation is insufficient. It is recommended to increase the ventilation volume and install a high-performance filter.
