chapter 26 Flashcards
The formation of clots to plug openings in injured blood vessels and stop blood flow
coagulation
The flow of blood through body tissues and vessels
perfusion
Very small, thin-walled blood vessels
venules
A life-threatening fracture of the pelvis caused by a force that displaced one or both sides of the pelvis laterally and posteriorly
open-book pelvic fracture
Bleeding
hemorrhage
A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions
shock
The smallest branches of arteries leading to the vast network of capillaries
arterioroles
The small blood vessels that connect arterioles and venules; various substances pass through capillary walls, into and out of the interstitial fluid, and then on to the cells
capillaries
A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular function
hypoperfusion
A nosebleed
epistaxis
Vomiting blood
hematemesis
The coughing up of blood
hemoptysis
A dressing impregnated with a chemical compound that slows or stops bleeding by assisting with clot formation
hemostatic dressing
The main artery leaving the left side of the heart and carrying freshly oxygenated blood to the body
aorta
A device to splint the bony pelvis to reduce hemorrhage from bone ends, venous disruption, and pain
pelvic binder
A blood vessel, consisting of three layers of tissue and smooth muscle, that carries blood away from the heart
artery
A mass of blood that has collected within damaged tissue beneath the skin or in a body cavity
hematoma
The blood vessels that carry blood from the tissues to the heart
veins
The bleeding control method used when a wound continues to bleed despite the use of direct pressure
tourniquet
A bruise from an injury that causes bleeding beneath the skin without breaking the skin
contusion
A device that provides proximal compression of severe bleeding near the axial or inguinal junction with the torso
junctional tourniquet
Narrowing of a blood vessel
vasoconstriction
Blood in the urine
hematuria
A buildup of blood beneath the skin that produces a characteristic blue of black discoloration as the result of an injury
ecchymosis
A hereditary condition in which the patient lacks one or more of the blood’s normal clotting factors
hemophilia
A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion
hypovolemic shock
