|
5L in Kg man1000 ml lost=20% of 5L3000ml of crystaloid (3:1 rule)

|
|
|
what urine output is a sign of adequate tissue perfusion
|
.5ml/kg/h

|
cardiogenic and hypovolemic shock are the same in all the following parameters except:decreased cardiac outputdegree of vasoconstricionoliguriamental obundationR and L filling pressure
|
filling pressure high in cardiogenic shock and low in hypovolemic shock
|
|
|
why is blood glucose elevated in acute hemorrhagic shock

stage III shock30-40% blood loss.3to .4*5L=1500-200L blood loss
