Tx to decrease preload - -Diuretics -Dilators (nitrates, nitroprusside, morphine) Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the AV valves close, just prior to ejection -As preload increases, SV and CO will increase up to a point -Too high of a preload may lead to heart failure -Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities Cardiac output equation - CO = HR x SV Components of str...

How does COPD result in atrial fibrillation and predisposition to PEs? - COPD causes pulmonary hypertension, right ventricular hypertrophy, and right atrial enlargement. The right atrial enlargement causes stretching of the atrial tissue and frequently results in atrial dysrhythmias. SA blocks, second-degree AV block type I, and third-degree AV heart block at the level of the AV node would occur in _______________ occlusion - RCA (as seen in inferior wall MIs) There is (more/less) risk of b...

2024 CVICU TEST STUDY GUIDE GRADED A+ SVO2 Mixed venous oxygen saturation (SvO2) is the percentage of oxygen bound to hemoglobin in blood returning to the right side of the heart. This refects the amount of oxygen "left over" after the tissues remove what they need. SVO2 Normal >60% Low SVO2 Inadequate oxygen delivery or increased oxygen consumption Ex: fever, pain, bleeding, infection High SVO2 increase in CO, decrease in oxygen demand, reduction in oxygen extraction Ex: anesth...
