WebAug 22, 2024 · The temperature of blood is measured at the tip. This produces a temperature-time curve. The area under the curve can be used to calculate cardiac output, as per the modified Stewart-Hamilton Equation: Q = V ( T B − T I) k 1 k 2 ∫ t 1 t 2 Δ T d t, where: Q = Cardiac output. V = Volume of injectate. T B = Temperature of blood. http://www.internationaljournalofcaringsciences.org/docs/Vol1_Issue3_02_Lavdaniti.pdf
