Experimental and clinical evidence point strongly toward the potential for microvascular stresses to influence the severity and expression of ventilator associated lung injury. Intense microvascular stresses not only influence edema but predispose to structural failure of the gas-blood barrier, possibly with adverse consequences for the lung and for extrapulmonary organs. Taking measures to low...
The purpose of protective clothing and other personal protective equipment (PPE) is to provide escape time, to reduce the burn injury level, and to prevent aggravation of the consequences to workers during exposure to an electric arc. In this study the flammability properties of 12 different types of flame-retardant fabrics were compared with the normally used flame spread test method (EN 532:1...
