Embodiments of the present disclosure generally relate to apparatus and methods for foam generation, and to apparatus and methods for evaluation of foam systems. In an embodiment, a method of analyzing foam properties includes delivering a foaming composition and a gas to a housing at a pressure of 500 psi to 6,000 psi and a temperature of 35° C. to 150° C., the housing containing an unconsolidated porous media. The method further includes flowing the foaming composition and the gas through the housing, and forming a foam by an interaction of the foaming composition, the gas, and the unconsolidated porous media. The method further includes directing the foam from the housing to a visualization chamber, the visualization chamber in fluid communication with the housing, and measuring a foam characteristic via the visualization chamber. The characteristic may include foam half-life, pressure drop through the unconsolidated media, and/or apparent viscosity of the foam.

In some embodiments, the invention provides an in vitro method for identifying a patient as likely as likely to require a transfusion of at least six units of blood in six hours or less. The method comprise, consists essentially of, or consists of (a) analyzing a sample of blood from a patient with a viscoelastic analysis assay to obtain a coagulation characteristic value that is independent of time of the patient; and (b) comparing the coagulation characteristic value of the patient to a coagulation characteristic value that is independent of time of a control, wherein the coagulation characteristic value of the patient that is lower than the coagulation characteristic value of the control identifies the patient as likely to require a transfusion of at least six units of blood in six hours or less.
