- Pumonary Infarct
- Is shock reversible?
- Pulmonary Thromboembolism
- Oncotic (albumin)
- a emobilzation to small distal vessels in lung may cause ischemic necrosis of tissue infarct
- b early stages of shock are reversible and treatable. in the early stages, peripheral vasoconstriction helps compensate for hypoperfusion. the central pooling redirects blood to vital organs. if untreated, can cause death.
- c -20 to 25 per 100,000 PTs have it
-fatal if 60% of circulation is obstructed
- d major factors KEEPING fluid in vessel
- e excess fluid in the interstital spaces of the body
5 Multiple choice questions
- mixed acidosis occurs. result of renal, anaerobic glycolosis, and respiratory insufficiency.
- hemorrhagic; organs with dual blood supply; soft aerated tissues
- pump failure; i.e. secondary to MI, conduction block or arrythmia, myocarditis or valvular heart disease
- increased inflow into a vessel; i.e. exercise, inflammation
- emboli that travel from venous arterial circulation via a communication between arterial and venous circulation
5 True/False questions
Shock → hypoperfusion of tissues; the circulatory system can no longer supply nutrients and oxygen to peripheral tissues.
Congestion (cyanosis/hypoxia) → decreased outflow of a vessel; i.e. local obstruction, congestive heart failure
3 causes of hypotonic shock → Allergen (bee sting), neurogenic (spinal cord, pain from trauma), and bacterial endotoxins (septic shock)
Disseminated Vascular Coagulation → a sudden onset of fibrin thrombi in the microcirculation with consumption of coagulation factors and formation of fibrin degradation products. Potential complication with widespread of thrombin.
Embolism → mixed acidosis occurs. result of renal, anaerobic glycolosis, and respiratory insufficiency.
