Abstract

We aimed to examine the method to for maintain a sanitary air environment in medical facilities. Nine medical facilities were induced in this study. The six factors influencing indoor air quality, namely, air temperature, relative humidity, air flow rate (velocity), CO, CO_2, and particle matter, were measured every minute for 6 h at 3 areas inside and outside the medical facilities. The concentrations of volatile organic compounds were also measured. The results were as follows: (1) The concentrations of CO_2 often exceeded 1,000 ppm because of insufficient ventilation and its inappropriate operation. (2) The concentration of particle matter outside the facility was clearly influenced by that inside the facility. (3) The concentration of p-dichlorobenzene, which is a component of insecticide applied to clothes, was related to the number of the people in the room. 4) Diethylene glycol monoethyl ether (DEGEE) and camphor were observed in these medical facilities.
