|
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
|
