Bleeding Flashcards
What is aorta?
The main artery that receives blood from the left ventricle and delivers it to all the other arteries that carry blood to the tissues of the body.
What is arterioles?
The smallest branches of arteries leading to the vast network of capillaries.
What is artery?
A blood pressure, consisting of three layers of tissue and smooth muscle, that carries blood away from the heart.
What is capillaries?
The small blood vessels that connect arterioles and venues, various substance pass through capillary walls, into and out of the interstitial fluid, and then on to the cells.
What is coagulation?
The formation of clots to plug openings in injured blood vessels and stop blood flow.
What is contusion?
A bruise from an injury that causes bleeding beneath the skin without breaking the skin
What is ecchymosis?
A buildup of blood beneath the skin that produces a characteristic blue or black discoloration as the result of an injury
What is epistaxis?
A nosebleed
What is hematemesis?
Vomited blood
What is hematoma?
A mass of blood that has collected within damaged tissue beneath the skin or in a body cavity
What is hematuria?
Blood in the urine
What is hemophilia?
A hereditary condition in which the patient lacks one or more of the bloods normal clotting factors.
What is hemoptysis?
The coughing up of blood
What is hemostatic agent?
A chemical compound that slows or stops bleeding by assisting with clot formation
What is hypoerfusion?
A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions; also called shock.
What is hypovolemic shock?
A condition in which low blood volume due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion
What is melena?
Black, foul smelling, tarry stool containing digested blood
What is open book pelvic fracture?
A life threatening fracture of the pelvis caused by a force that displaces one or both sides of the pelvis laterally and posteriorly
What is open book pelvic fracture?
A life threatening fracture of the pelvis caused by a force that displaces one or both sides of the pelvis laterally and posteriorly
What is pelvic binder?
A device to splint the bony pelvis to reduce hemorrhage from bone ends, venous disruption and pain
What is perfusion?
The circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cells
What is shock?
A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions also called hypoperfusion
What is tourniquet?
The bleeding control method used when a wound continues to bleed despite the use of direct pressure
What is vasoconstriction?
The narrowing of a blood vessel such as with hypoperfusion or cold extremities
