Therapeutic management of shock requires consideration on current pathophysiological mechanisms. Therefore an extended monitoring of hemodynamics including application of a Swan-Ganz-Catheter is necessary to measure SvO2, CO, PCWP and SVR in critically ill patients. Measurements of O(2)DEL, O2CONS and avDO(2), reproducing more exactly tissue perfusion and oxygenation, allow investigation of therapeutic strategies. Due to new concepts fluid resuscitation is reduced in favour of early and more differentiated use of catecholamines. As an extracorporeal support hemofiltration today is established mainly in treatment of septic shock.
