Der Nationalstaat und die Kultur, percentage of the pathogenic organisms in an air stream. Because of this low efficiency most authorities believed it was better to use all outdoor air which contained fewer pathogenic organisms than to reuse, by recirculation, the more contaminated air from within the hospital for the ventilation o

Symbole und Namen des Nationalstaats,tion upon solid surfaces, impingement into liquids and filtration. A variety of equipment is also available for sampling of airborne particulates. With regard to surface sampling of microbial contamination one of three basic methods is usually employed; swabbing, agar plate impression, or the direct

Most of the results reported are related to conventional air conditioned facilities while others are related to research facilities for the study of recirculation, in addition to sampling of earlier types of recirculation systems as described in Chapter 2. Also, quantitative and qualitat

Therefore, this chapter will review the theory of laminar airflow control, its origin and present-day application in clean rooms, laboratory facilities, pharmaceutical field, etc.

https://doi.org/10.1007/978-3-322-96280-5ory. The fundamentals of this concept have been described in Chapter 7. On the assumption that a considerable number of wound infections are caused by airborne bacteria, many researchers and hospitals have pressed for installations in operating rooms used for routine as well as special surgical proc
