Post-resuscitation circulatory shock occurs in most patients admitted after out-of-hospital cardiac arrest (OHCA) and is a primary contributor to subsequent mortality [1,2,3].Optimal hemodynamic management of post-resuscitation shock is complicated by the myriad pathophysiological processes involved—which together are termed post-cardiac arrest … It has details on shock tables . The gas is assumed to be ideal air. What does the number 0.3238 represent? Find this helpful? M Ideal Gas. Normal Shocks As previously described, there is an effective discontinuity in the flow speed, pressure, density, and temperature, of the gas flowing through the diverging part of an over-expanded Laval nozzle. , the post normal shock Mach number, In real life supersonic flow applications, normal shocks as the ones studied in Chapter 3 appear in very specific situations only. Oblique Shock Calculations This form calculates properties of air flow through an oblique shock wave.
