Abstract:
Objective:To monitor the air quality of the air pressurized oxygen chamber in a hospital in real time, and conduct hygienic evaluation.Methods:Based on the data collected from the WeChat interface from July 20, 2020 to July 27, 2020 and the background data of the air dynamic monitoring system based on the Internet of Things from July 6, 2020 to July 10, 2020, we tested, recorded, and carried out a descriptive analysis of some air quality indexes and noise of the air pressurized oxygen chamber (temperature, humidity, formaldehyde, TVOC, CO 2, PM10, PM2.5). We evaluated the air quality in the pressurized oxygen chamber according to the Indoor Air Quality Standard GB/T 18883—2002, and provided some suggestions on optimization. Results:The detection results showed that all the indicators fluctuated greatly. The indicators of CO 2 and particulate matters had exceeded the standards multiple times. After the disinfection, the TVOC and formaldehyde concentrations had increased rapidly or even exceeded the standards. Conclusion:There was a problem with the air quality in the air pressurized oxygen chamber. It will enhance the therapeutic effect of hyperbaric oxygen by strengthening the management of personnel and equipment, improving the environment in the medical air pressurized oxygen chamber, and further monitoring of the air pressure, oxygen concentration, and the total amount of bacteria in the chamber.
