Chapter 36- Oxygenation: Cardiovascular Function Flashcards
angina
pain and discomfort about the heart characteristics or myocardial ischemia; sever pain felt in the anterior chest, shoulder,left arm, neck and jaw
automaticity
hearts capability of generating its own electrical impulse, which is then conducted through specialized fibers
cardiac output (CO)
the amount of blood pumped by the heart every minute
contractility
force of contraction
diastole
period of rest in the cardiac cycle, when the ventricles are not contracting and the coronary arteries are filled with blood
dysrhythmia
abnormality in heart rhythm
intermittent claudication
limb pain caused by poor bloodflow
ischemia
insufficient blood supply to a bodypart due to obstruction of circulation
myocardial infarction
“heart attack”; hypoxicity of heart muscle and death of portions of the heart muscle from decreased blood flow through the coronary artery
myocardium
layer of cardiac muscle that forms the wallsof the heart
perfusion
passing of blood through an area
sequential compression devices (SCDs)
promote veous return from legs to decrease the risk of deep vein throbosis and pulmonary embolism in clients with reduced mobility
shock
severe circulatory insufficiency
stroke
cerebrovascular accident (CVA); involves a sudden onset of hemorrhage; blood clots, or other vascular lesions, causing damage to the brain
systole
period of concentration of the ventricles
