Document Summary
Difficulties with oxygenation due to inadequate tissue perfusion. Heart failure occurs due to : preload volume coming into ventricles from atria (cid:498)end diastolic pressure(cid:499) like fluid, afterload resistance ventricle must overcome like hypertension, vasoconstriction. Our heart as a pumping organ overload, valve regurgitation: cardiomyopathy, myocardial infarction, fluid overload, aorta or aortic valve disorders, cardiac arrythmias, severe anemia. Left-sided heart failure: what your patient looks like : backward effects, dyspnea on exertion, orthopnea, cough, paroxysmal nocturnal dyspnea, cyanosis, basilar crackles, forward effects, fatigue, oliguria, increased heart rate, faint pulses. Or stand: drop legs down lower, oxygen, ?intubation, ventilator need, diuretics, treat causes, digoxin. Right-sided heart failure: what your patient looks like: backward effects, hepatomegaly, ascites, splenomegaly, anorexia, subcutaneous edema, peripheral edema. Jugular vein distention: forward effects, fatigue, oliguria, increased heart rate, faint pulses. Insomnia: activity intolerance, gas exchange, fatigue, and , monitoring what, diet, water, salts support knowledge, insomnia, fatigue.
