Fungi in used bedding materials.
Few workers have been concernied with the occurrence of bacteria and fungi withini used beddinig, bedding materials, anid upholstered furniture. Such organisms may be present in the raw materials, added during normal use and storage, multiply under certaiin conditions of humidity, and may be transferred to new felt when new and used materials are garnetted. Conant et al. (1935) studied the mold...
متن کاملResistance to airflow through bedding materials used in infancy.
Various bedding materials used in infancy, including duvets (or continental quilts), were tested for airflow using the British Standards Institution tests for pillows or fabrics. Resistance was also measured when the items were placed on a dummy infant face. Measurements were made on washed and unwashed garments, which were tested both dry and wet. Results suggest that all the bedding materials...
متن کاملMechanical model testing of rebreathing potential in infant bedding materials.
Rebreathing of expired air may be a lethal hazard for prone sleeping infants. This paper describes a mechanical model to simulate infant breathing, and examines the effects of bedding on exhaled air retention. Under simulated rebreathing conditions, the model allows the monitoring of raised carbon dioxide (CO2) inside an artificial lung-trachea system. Resulting levels of CO2 (although probably...
متن کاملGrowth of environmental mastitis pathogens in various bedding materials.
The objective of the study was to determine whether, under controlled conditions, bedding materials vary in their ability to support growth of different environmental pathogens independent of the presence of feces, urine, or other contamination. Five sterilized bedding materials (fine hardwood chips, recycled dried manure, chopped newspaper, softwood sawdust, and chopped straw) and three bacter...
متن کاملEvaluation of materials used for bedding encasement: effect of pore size in blocking cat and dust mite allergen.
BACKGROUND Mattress and pillow encasings are recommended for patients allergic to dust mites. Many encasements block allergen and are vapor permeable but do not allow free passage of air through the material. Recently, breathable fabrics made from tightly woven synthetic fibers or nonwoven synthetics have been recommend as encasements. OBJECTIVE The purpose of this study was to develop a meth...
