- 5 types of embolisms
- Decompensated shock
- Irreversible shock
- a 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.
- b Thrombi, fat, amniotic fluid, foreign substances, and bone marrow
- c hemorrhagic; organs with dual blood supply; soft aerated tissues
- d -20 to 25 per 100,000 PTs have it
-fatal if 60% of circulation is obstructed
- 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.
- Allergen (bee sting), neurogenic (spinal cord, pain from trauma), and bacterial endotoxins (septic shock)
- hypoperfusion of tissues; the circulatory system can no longer supply nutrients and oxygen to peripheral tissues.
- major factors PUSHING fluid out of vessel
- mixed acidosis occurs. result of renal, anaerobic glycolosis, and respiratory insufficiency.
5 True/False questions
Is shock reversible? → 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.
Pathology of shock → (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.
Patho of Pulmonary Thromboembolism → deep venous thrombi is usual cause; often following immobilization, i.e. bed rest from hospitalization
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 → a detached solid, gaseous, or liquid mass that is carried by the blood from site of origin to a distal site. May lodge in pulmonary or systemic circulation.
