How does dobutamine affect cardiac output
Did you know?
WebPreload, afterload, and cardiac contractility affect cardiac output in the following ways: Preload: An increase in preload increases cardiac output by increasing the force of contraction, resulting in an increase in stroke volume. However, there is an optimal level of preload beyond which further increases result in decreased cardiac output due ... WebCardiac dysrhythmias. Dobutamine increases cardiac output after acute myocardial infarction without exacerbating myocardial infarction or ventricular dysrhythmias. …
WebIt does cause venoconstriction, which may increase preload. Its dominant effect on cardiac output is often to cause a reduction (but this may depend on the heart's ability to tolerate … WebNY). The cardiac output was recorded as the mean of three measurements. The other parameters were re- corded as the mean of ten cardiac cycles coincident with each of the three cardiac output curves. Heart rate was determined from a simultaneous ECG recording. Arte- rial blood pressure was measured from a fluid-filled cath-
WebTherapeutic Effect (s): Increased cardiac output without significantly increased heart rate. Pharmacokinetics Absorption: Administered by IV infusion only, resulting in complete bioavailability. Distribution: Unknown. Metabolism and Excretion: Metabolized by the liver and other tissues. Half-life: 2 min. TIME/ACTION PROFILE (inotropic effects) WebIn patients with advanced congestive heart failure both nitroprusside and dobutamine improve cardiac output, with different adaptations of left ventricular performance and left …
