Shock Shock is a condition in which blood flow to cells and tissues is inadequate. There is insufficient oxygen and nutrients available for cells which cause cellular hypoxia and cell death. Organ failure and death is likely if not treated Patho of shock Decreased blood supply to cells result in the following cellular changes: Cells lack oxygen, nutrients and energy. Cells start to produce energy through anaerobic metabolism. Anaerobic metabolism produces lactic acid and increased acidity cause...

4 IGORRIVIN f irst, let’s talk about what it means for some property P to be generic for some (possibly) infinite (but countable) set S. 3. Anidealist approach to randomness First, define a measure of size v on the elements of S. This should satisfy some simple axioms, such as: (1) v(x) ≥ 0 for all x ∈ S. (2) The set Sk = {x ∈ S|v(x) ≤ k} is finite for every k. Let now P be a predicate on the elements of S– think of a predicate as just a function from S to {0,1}...
