BME 210 - Spring 2008 Measuring Cardiac Output Solutions - 50 points Problem Statement and Background a) Define the problem Cardiac output, the volume of blood pumped by the heart in a given period of time (usually one minute), is one of the most important variables for assessing the cardiovascular system, though very hard to measure in the intact human cardiovascular system. b) Indicator Dye Dilution Technique Dye dilution is the technique used to measure cardiac output in this project. The technique involves injecting a known amount of dye (indicator substance) into the venous blood, and then continuously measuring its concentration in the arterial blood. The concentration-time profile is then corrected for re-circulation. In this project, the given corrected concentration-time data was analyzed using 3 different numerical methods to obtain the area under curve (AUC), which in turn was used to determine cardiac output using the following formula: Cardiac Output = D / AUC, where “D” is the amount of dye injected into the system at time 0. c) Equations
