  3. 2. Some Aspects on Contamination Control in Hospitals- Observations and Measurements

    Författare :Catinka Ullmann; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source strength; Tissue and cells establishments; Ultraclean air operating rooms; Microbial cleanliness; Autoclaves; Contamination control; Door openings; Airborne contamination risks;

    Sammanfattning : Measurements of the cleanliness level have been performed in operating rooms classified as tissue and cells establishments for bone tissue to compare the results with the requirements given in the Tissue and Cells Directives of the European Union (EUTCD). The results show that the requirements are not always fulfilled. LÄS MER

  4. 3. Dispersion and risk assessment of airborne contaminants in pharmaceutical clean rooms

    Författare :Berit Reinmüller; KTH; []
    Nyckelord :airborne contamination; clean rooms; clean zones; clothing systems; dispersion of contaminants; LR-Method; microbiological risk assessment; risk assessment; source strenth;

    Sammanfattning : In many of today's industries, particularly in the healthcare field, special protection is required against airbornemicrobiological contamination. Clean rooms and clean zones areused to separate the ambient environment from contaminationcontrolled areas. LÄS MER

  5. 4. Platinum Group Elements in Birds of Prey

    Författare :Kristine H. Ek; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rhodium; bird of prey; platinum; laser ablation; palladium; ICP-MS; airborne particles;

    Sammanfattning : The environmental concentrations of Pd, Pt and Rh (three of the platinum group elements, PGE) have increased since the introduction of exhaust catalysts on automobiles. A limited understanding of the environmental distribution and effects of the platinum group elements has raised concern over their potential biological availability. LÄS MER

  7. 5. Wound ventilation : a new concept for prevention of complications in cardiac surgery

    Författare :Mikael Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cardiac surgery; air embolism; airborne contamination; wound infection; desiccation; adhesion; carbon dioxide insufflation; antiseptic agent; ethanol; humidification;

    Sammanfattning : Cardiac surgery through an open chest wound is a major operation both in size and duration. The wound exposure to ambient air implies considerable risks. 1) Air may enter the heart and great vessels and embolize to the brain or cardiac muscle where it may cause dysfunction or permanent damage.
