Terms in this set (52)
blood flow of the heart Superior or inferior vena cava -> right atrium->
tricuspid valve -> right ventricle -> pulmonic valve->
pulmonary artery-> lungs -> pulmonary vein -> left
atrium-> bicuspid valve -> left ventricle -> aortic
valve-> aorta-> tissues and rest of body
left side receives what kind of blood oxygenated
electrical impulse of heart SA, AV, Bundle of His, Purkinje fibers
, Normal CO 4-8 L/min
normal stroke volume 70 ml/beat
preload amount of blood in ventricles before systole/amount
of blood sitting the ventricles at the end of diastole
right ventricle failure Right ventricle failure= backs up into superior and
inferior vena cava, provide diuretics and vasodilators,
talk to patient about drinking less fluid, monitor
patients weight
left ventricle failure hypertension and MI, backs up into lungs, resp
symptoms, elevate patients head or bed, diuretic, fine
crackles. increase HOB manage patients I&O's
What causes coronary artery disease? Narrowing of coronary arteries (atherosclerosis),
buildup of plaque can occlude coronary arteries
anticoagulants for heart failure warfarin (coumadin) and heparin, warfarin has a
slower onset but is long term, vitamin k is warfarin
reversal agent, monitor carefully for signs and
symptoms of bleeding, heparin or enoxaparin= given
first few days
COPD impaired airflow in the lungs
Damage to alveolar wall and loss of elasticity
Emphysema and chronic bronchitis (caused by
smoking)
Air becomes trapped in alveoli due to difficult
expiration; chest becomes hyperinflated (barrel
chest), chronic cough, difficulty clearing mucus
Elevate HOB when dyspnea, postural drainage
Asthma bronchial narrowing or obstruction (genetics and
allergens can contribute)
Recognize w/ dyspnea, cough, wheezing
priority actions: reopen bronchial tree (emergency
inhaler)
