Abstract:
Objective To understand the air quality of the hospital clean operating rooms and the effecting factors in Guangzhou city, China. Methods In Jan-Oct, 2006, 18 clean operating rooms in five large scale hospitals were chosen and the related indexes such as airborne particles and airborne bacterial concentration were tested according to GB/T16292-1996 Test Method for Airborne Particles in Clean Room of Pharmaceuticalindustry, GB/T16293-1996 Test Method for Airborne Microbe in Clean Room of Pharmaceuticalindustry, GB/T 18204-2000 Standard Examination Methods for Public Places. The results were evaluated according to Architectural Technical Code for Hospital Clean Operating Department (GB50333-2002). Results The concentration of airborne particles and bacteria in the investigated clean operating rooms were eligible with a qualified rate of 100%. A correlation was seen between the airborne particles and bacteria, the correlation coefficients were 0.306 for the particle of 0.5 ?m and 0.074 for the particle of 5.0 ?m. The qualified rate of other items such as the static pressure difference, illuminance, relative humidity, temperature, noise, wind velocity and air exchange rate were respectively 100%, 94.4%, 88.9%, 83.3%, 83.3%, 83.3%, 33.3% and 38.5%. Conclusion The qualified rate of the main clean indexes of the clean operating rooms in hospitals in Guangzhou city is comparatively high, but some of the other indexes related to the air quality should be paid more attention in usual application and maintenance.
