Clotting Flashcards
A physiologic process in which blood is converted from a liquid to a semisolid gel
Clotting
When the problem extends to entire body; is usually the result of a significant hematologist event
Systemic Clotting
When the problem is localized; is usually a problem in a vein or an artery, either injury to a vessel or a clot within a vessel.
Localized Clotting
Clotting Process:
First Response is ___
Vasoconstriction
Clotting Process:
Second Response is ___
Platelet plug formation
Clotting Process
Third Response is ___
Thrombin—>Fibrinogen to form insoluble fibrin=stabilized clot
Clotting Process
Fourth response is ___
Breakdown of the clot
Factors that are activated by contact with collagen that has been exposed from damaged vessel wall
Intrinsic Factors
Damaged Tissue
Exposure of the tissue factor to extra vascular injuries
Extrinsic Factors
Process of breaking up a clot
Starts with plasminogen
Plasmin
Fibrin splits products
Fibrinolysis
Breaking up a clot
Prevention of a DVT
Early ambulation: easiest & most cost effective method to decrease VTE risk
PA of a DVT
Pain-calf or groin area
Swelling of the calf/leg or extremity
Compare the ext. with the other(measure)
Warmth and/or redness to compare
A test to see how blood moves through your arteries and veins
Venous Duplex Ultrasonography
measure changes in volume in different parts of the body to check for blood clots in the arms and legs
Plethysmograph
Inhibits clotting factors
Stops fibrin production
Prevents further clots
Prevents current clot from getting bigger
Existing clot slowly dissolves overtime
Heparin
