Chapter 25 Bleeding Flashcards
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
Arterioles
The smallest branches of arteries leading to the vast network of capillaries
Artery
A blood vessel, consisting of three layers of tissue and smooth muscle, that carries blood away from the heart
Capillaries
The small blood vessel’s that connect arterioles and venules ; various substances pass through capillary walls, into and out of the interstitial fluid, and then on to the cells
Coagulation
The formation of clots to plug openings in injured blood vessels and stop blood flow
Contusion
A bruise from an injury that causes bleeding beneath the skin without breaking the skin
Ecchymosis
A build up of blood beneath the skin that produces a characteristic blue or black discoloration as the result of an injury;
Epistaxis
A nosebleed
Hematemesis
Vomiting blood
Hematoma
A mass of blood that has collected within damaged tissue beneath the skin or in a body cavity
Hematuria
Blood in the urine
Hemophilia
A hereditary condition in which the patient lacks one or more of the plants normal clotting factors
Hemoptysis
The coughing up of blood
Hemorrhage
Bleeding
Hemostatic agent
A chemical compound that slows or stops bleeding by assisting with clot formation
Hypo perfusion
A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions; also called shock
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
Melena
Black, foul smelling, tarry stool containing digested blood
Open book pelvic fracture
A life-threatening fracture of the pelvis caused by a force that this place is one or both sides of the pelvis laterally and posteriorly
Pelvic binder
A device to splint the bony pelvis to reduce hemorrhage from bone ends, Venus disruption, and pain
Perfusion
The circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cells
Shock
A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions; also called hypo perfusion
Tourniquet
The bleeding control method used when a wound continues to bleed despite the use of direct pressure; useful if a patient is bleeding severely from a partial or complete amputation
Vasoconstriction
The narrowing of a blood vessel such as with hypo perfusion or cold extremities
Veins
The blood vessels that carry blood from the tissues to the heart
Venules
Very small, thin walled blood vessels
