- Compensated shock
- 4 Arterial Thrombi outcome
- Pulmonary Thromboembolism
- Pathology of shock
- Decompensated shock
- a -20 to 25 per 100,000 PTs have it
-fatal if 60% of circulation is obstructed
- b a set of adaptations occur to compensate for the circulatory imbalance. i.e. tachycardia, vasoconstriction of peripheral arteries, and reduced urine production
- c (upon autopsy) interal organs are congested and wet from edema; the lungs are 2-3 times heavier. the liver is congested and blood oozes from it. the intestines are dark from blood pooling and wet. the kidneys are swollen, pale, and congested. and the brain is edematous, flattened gyri.
- d 1. resolution
3. embolization (arterial)
*all similar to venous thrombi
- e when early shock fails: hypotension occurs, BP and CO fall. Tachypnea and SOB lead to heart failure and pulmonary edema causing anoxia, lead to ARDS.
5 Multiple choice questions
- constriction of the renal cortical vessels reduces GFR. results in renal output.
- white; organs with single blood supply
- adherent masses of blood that have areas of pale alternating with areas of red - lines of zahn
- major factors KEEPING fluid in vessel
- the end result of decompensated shock. marked by: circulatory collapse, hypoperfusion of vital organs, and loss of vital functions. PTs are in distress and are frantic, DIC is common, and high mortality.
5 True/False questions
Hydrostatic Pressure → loss of peripheral vascular tone and pooling of blood in dilated peripheral blood vessels
Hyperemia (erythema) → increased inflow into a vessel; i.e. exercise, inflammation
Hypotonic shock → loss of peripheral vascular tone and pooling of blood in dilated peripheral blood vessels
Embolism → mixed acidosis occurs. result of renal, anaerobic glycolosis, and respiratory insufficiency.
Pumonary Infarct → hemorrhagic; organs with dual blood supply; soft aerated tissues
