Fick equation - Study guides, Class notes & Summaries

What is the Fick equation? correct answers VO2 = Q x a-vO2 difference Describe each component of the Fick equation in lay language. correct answers VO2 = maximal oxygen uptake Q = cardiac output a-vO2diff = arterial-mixed venous oxygen difference Cardiac Output (Q) correct answers Q = HR x SV - volume of blood ejected by the heart each minute (L/min) - Heart rate (HR): number of times the heart beat per minute (beats/min) - Stroke volume (SV): volume of blood ejected by the heart each...

What formula is used to determine cardiac output? Fick Equation What is the normal range for cardiac output? 4-8 LPM What are the units that measure cardiac index? L/min/m^2 (cardiac index = cardiac output / body surface area) [body surface area for most patients is about 2 m^2] What is the normal range for cardiac index? 2-4 L/min/m^2 If a patient is bleeding during bronchoscopy, you would administer _______________ down the bronchoscope. Epinephrine (a vasoconstrictor) If a patient is c...

Which of the following is the largest component of total energy expenditure (TEE)? A. RMR B. Thermic effect of digestion C. Physical Activity D. Metabolic Stress CORRECT ANSWER *A. RMR* The thermogenic effect of digestion is generally thought to contribute to no more than 10% to TEE. Activity contributes to 5% - 30% to TEE. With the exceptions of burn and sepsis, metabolic stress contributes to less than 50% TEE. However, in almost all situations, RMR constitutes 60% to 75% of TEE. Whi...
