In DIC, the processes of coagulation and fibrinolysis are dysregulated, and the result is widespread clotting with resultant bleeding. Regardless of the triggering event of DIC, once initiated, the pathophysiology of DIC is similar in all conditions. One critical mediator of DIC is the release of a transmembrane glycoprotein called tissue factor (TF).
Rigid polyurethane and polyisocyanurate foams will, when ignited, burn rapidly and produce intense heat, dense smoke and gases which are irritating, flammable and/or toxic. As with other organic materials the most significant gas is usually carbon monoxide. Thermal decomposition products from polyurethane foam, consist mainly of carbon monoxide, benzene, toluene, oxides of nitrogen, hydrogen cyanide, acetaldehyde, acetone, propene, carbon dioxide, alkenes and water vapor.
Mattress comfort layers-Polyurethane foam. Polyurethane (also called polyfoam or just poly) is the most common type of foam you will see in mattress comfort layers and it is used in almost all mattresses made by the major manufacturers or sold in larger outlets.t will last longer than the lower density conventional polyfoam, has better compression and performance qualities, it is suitable for use in a comfort layer when used reasonably (layers that are not too thick) or with slightly firmer foam.
