Necessity of particulate pollutant control in clean operating environment

The control of the airborne microorganism is always the top object based on the need of surgical infection control. Nevertheless, the aseptic particulate pollutant, i.e. nonbio-particle, causes numerous surgery complications as well, including chronic abdominal pain, peritoneal adhesion, granuloma, female infertility, and implanted artificial joint loosening or failing etc. The size of the particulate pollutant causing complications ranges from smaller than 0.1 μm to several millimeters. The particles of 0.3-10 μm in size are considered to be the most biologically active. So the clean air conditioning system of operating environment must meet the requirements of controlling both of the airborne microorganism concentration and the aseptic particulate pollutant.
