Standardizing performance-based criteria for support surfaces.

Abstract

Due to the sparsity of prospective, controlled, clinical studies on the efficacy of and the lack of standardized information about support surfaces, current literature does not clearly define how these surfaces address patient needs. Standardization would help healthcare professionals make better informed decisions about the use of support surfaces. Standardization would also help researchers design and implement controlled, clinical studies by defining characteristics of surface evaluation, making it possible to replicate research activities. The first step toward standardization is to develop a performance-based set of criteria for classifying these surfaces. With respect to the three purposes identified: comfort, postural control and pressure management, only parameters that can be measured noninvasively, have been considered. The nine parameters are life expectancy of the surface, skin moisture control, skin temperature control, redistribution of pressure, product service requirements, fail safety, infection, flammability, and patient/product friction. Specific guidelines for each of these nine parameters are discussed in depth. With testing and evaluation of support surfaces standardized, clinicians will be able to choose a surface to meet the needs of patients the same way they make other treatment decisions: based on outcomes and the results of controlled, clinical studies.

Characterization of volatile organic compounds in smoke at experimental fires.

Significant associations between firefighting and cancer have been reported; however, studies finding toxic products of combustion at municipal fires have been limited by (1) technical difficulties encountered at the scene of working fires, (2) the lack of a coherent sampling strategy, and (3) the absence of verified sampling methods. The objective of the present study was to characterize the presence of volatile organic compound (VOC) combustion products in fire smoke. Air samples from experimental fires burning various materials commonly found at structural fires were collected into evacuated Summa canisters and analyzed for 144 target VOCs using cryogenic preconcentration and gas chromatography/mass spectroscopy (GC/MSD) methodology. The resulting chromatograms were characterized by a small number of predominant peaks, with 14 substances (propene, benzene, xylenes, 1-butene/2-methylpropene, toluene, propane, 1,2-butadiene, 2-methylbutane, ethylbenzene, naphthalene, styrene, cyclopentene, 1-methylcyclopentene, isopropylbenzene) being found in proportionately higher concentrations in all experimental fires and accounting for 65% (SD = +/-12%) by mass of total measured VOCs. Benzene, toluene, 1,3-butadiene, naphthalene, and styrene were found at higher concentrations than most other VOCs and increased with the time of combustion together with increasing levels of carbon monoxide. Benzene was found in the highest concentrations, with peak levels ranging from 0.6 ppm to 65 ppm, while the levels of 1,3-butadiene, styrene, and naphthalene peaked at 0.1, 0.4, and 3 ppm, respectively. This study revealed that there were no new or novel, toxic nonpolar VOCs resulting from the burning of common building materials. This is important in view of the studies that have found associations between firefighting and various forms of cancer.
