Abstract

The objectives of the study were to evaluate cleanliness classes and airborne particle concentrations in typical operating theatre environments in Finland. At rest the cleanliness classes of the theatres fulfilled the guiding reference values when there was overpressure in the theatres. At operation the cleanliness classes were between ISO 7 and ISO 9. The airborne bioburden samples analysed showed that >85% of the sites evaluated had air of either good or inadequate quality. The results and suggested hygiene limits are benchmarked with methods and qualification limits of a standard draft prepared by the European hospital ventilation working group CEN/TC 156/WG 18.
