- Hypotonic shock
- Decompensated shock
- Patho of Pulmonary Thromboembolism
- Compensated shock
- Hydrostatic Pressure
- a 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.
- b deep venous thrombi is usual cause; often following immobilization, i.e. bed rest from hospitalization
- c a set of adaptations occur to compensate for the circulatory imbalance. i.e. tachycardia, vasoconstriction of peripheral arteries, and reduced urine production
- d loss of peripheral vascular tone and pooling of blood in dilated peripheral blood vessels
- e major factors PUSHING fluid out of vessel
5 Multiple choice questions
- ischemic necrosis of tissue distal to an area of arterial occulsion or in an area of obstructed venous outflow
- loss of blood volume; i.e. hemorrhages, water loss from burns, vomitting/diarrhea
- 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.
- hypoperfusion of tissues; the circulatory system can no longer supply nutrients and oxygen to peripheral tissues.
- -20 to 25 per 100,000 PTs have it
-fatal if 60% of circulation is obstructed
5 True/False questions
Pathology of shock → pump failure; i.e. secondary to MI, conduction block or arrythmia, myocarditis or valvular heart disease
Sequelae → sudeen death, clinically silent; resolution, organization, dyspnea, pulmonary infarct
Oliguria → constriction of the renal cortical vessels reduces GFR. results in renal output.
Edema → excess fluid in the interstital spaces of the body
Pumonary Infarct → white; organs with single blood supply
