WebExpert Answer. The dye dilution method is used to measure cardiac output with 7mg of dye, using the following formula: Cardiac output = ∫ 011( Concentration of dye )dt Quantity of dye The dye concentrations, in mg/L, are modeled by c(t) = 41t(11 −t),0 ≤ t ≤ 11, where t is measured in seconds. Find the cardiac output, accurate to at ... WebDec 13, 2024 · Cardiac output measurement by indicator dilution method is an invasive technique that measures the amount of blood ejected by the heart every minute for peripheral circulation in the whole body. The method involves injecting an indicator, which may be a dye, thermal, or saline solution into the venous blood, and its concentration is …
WebThe original dye dilution technology requires direct, continuous, and invasive blood sampling through a cuvette for measurement of the injected indicator (e.g., ICG) in arterial blood for the acquisition of a dye dilution curve. Consequently this cannot be regarded as a clinical method of cardiac output estimation, especially in small children. WebMethod i) Known quantity of dye (indocyanine green) or indicator substance (lithium) is injected into a central vein & measured distally from peripheral artery ii) Graph of concentration over time is plotted iii) A second peak seen on the concentration time curves due to recirculation = RECIRCULATION HUMP
