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...

A patient develops atrial fibrillation after abdominal surgery. Her blood pressure falls from 110/70 mm Hg to 92/68 mm Hg. The hypotension is related to which of the following? a. Decrease in ventricular contractility b. Hypovolemia c. Mural thrombi d. Decrease in ventricular filling - Correct answer: d Rationale: The contribution that atrial contraction makes to ventricular filling volume is approximately 15% to 30%. Atrial fibrillation results in quivering but not contracting atria. The...
