Abstract:

A survey is presented with data from 27 operating rooms in four county councils, where information from
111 ongoing surgical operations was given regarding air volume flows, measured concentration of airborne
viable particles and used clothing systems. With results from the survey the mathematical expression

present in the operating room during ongoing surgery. As well supply air system as surgical clothing system
used play here an important role
