| Research Abstract |
It is universally recognized that clean environment should be strictly maintained in hospitals. As a matter of fact, however, cleanliness of the environment xometimes is not kept at a satistactory level, which results in an unexpected accident, namely, hospital acquired infection.
Clean environment of hospitals should extend to hospital space and everything therein including people, medical instruments, materials and other elements.
This paper focuses on air environment, one of these elements constituting clean hospital environment and discusses air pollution problems.
In order to grasp the status-quo of the air pollution in hospitals and to establish a measuring method thereof, the author has conducted air quality measurement survey in the CB General Hospital. Some of the findings are shown as follows;
Airborne partiles are affected more strongly by human behaviours than by the number of those present in the room.
Airborne particulate concentration in the operating room is affected much by the door opening/closing and human entrance/exit movements.
Minute particles ( D<eqorgt>0.3<micrn>m, 0.5<micrn>m ) can be controlled only by infroducing highly clean air. Plrifying effect by way of controlling human presence and maitaining the clean level of the work is observed only on large particles.
Among the waiting spaces in a hospital, waiting space in clinic tends to suffer from high pollution as a result of mal-distribution of air currents.
Hospital buildings should be recognized as part of medical treatment, and it thus should be understood that maitaining clean air environment is a method of medical treatment.
