Some Aspects on Contamination Control in Hospitals- Observations and Measurements
A theoretical study describes the influence of door-openings to the microbial air cleanliness of ultraclean air operating rooms for infection prone surgery. The results explain why door openings sometimes increase the level of airborne bacteria-carrying particles in the operating rooms. Temperature differences increase the air volume flows through the door openings and differences in concentration levels increase the contamination risks.
A comparison is presented between airborne cleanliness requirements for pharmaceutical manufacturing (EU GMP Annex 1) and recommendations for ultraclean air operating rooms and differences are discussed

The purpose of this thesis is, by an engineering approach, to increase the understanding and awareness of some contamination risks in different
environments of Swedish hospitals. The work is based on observations and results
of measurements in different environments within hospitals with focus on contamination control.
