9 Cards in this Set

  • Front
  • Back
obstructive 2 types
outflow: PA - pulmonary embolism and aortic/pulm valve stenosis

Inflow:PT - pericardial effussion and Tamponade
Cardiogenic
decr supply blood to organs

inadequate CO = HR X SV

INCR HR -- DECR CO and SV
Hypovolemic 2 types
Absolute hypovolemia: hemorrhage and dehydration (inad. intake or excess outflow)

Relative hypovol: 3rd spacing - ascites
Vasodilatory
blood vessel dilate but same vol of blood goes through.
Anaphylaxis: systemic allergy
Neurogenic: sympathetic vasomotor
Septic: sever infection (WBC >12)
Inflam mediators- TNFalpha & IL-1B: Protease production
cause cell damage -> cell dysfunction -> imbalance btw O2 delivery and demands -> organ dysfunction & failure
Inflam mediators TNFalpha & IL-1B: prostag production
vasodilation -> impaired tissue perfusion -> imbalance btw oxygen delivery and demand -> organ dysfunction and failure
inflam mediators TNFalpha & IL-1B: clotting cascade
impaired tissue perfusion -> imbalance btw oxygen delivery and demands -> organ dysfunction and failure
inflam mediators IL-8: tissue inflammation
cell damage -> cell dysfunction -> imbalance etc
Coagulation cascade
induce blood monocytes and vascular endothelial cells to express tissue factor; deplete protein C; incr levels of plasminogen activator inhibitor -> prevents fibrinolysis
