Mean cardiac index (CI) by the Fick method was 7.18卤2.18 Lit./min/mand by echo was 7.58卤1.94 Lit. /min/m. There was a significant correlation between them (P<0.001). By regression analysis the following formula was obtained showing the relation (r=0.919, P<0.0001, r=0.85): Cardiac...

An FiO2 >0.3 is likely to result in oxygen being dissolved in the blood, which should be taken into account in the Fick calculations by measuring PaO2. Even though it is recommended that PaO2 is measured in such cases, it is recognized that the above formula gives a low relative importance...
The important concept implicit in this formula is that the hemodynamic evaluation of a stenotic valve requires that the pressure gradient across that valve be examined in light of the cardiac output passing through the orifice. The concept asserts that if an accurately obtained pressure gradient can...
Comparison between cardiac out- put measured by thermodilution technique and calculated by O2 and modi- fied CO2 Fick methods using a new metabolic monitor. Intensive Care Med 1997; 23: 908-915.Brandi LS, Bertolini R, Pieri M, Giunta F, Calafà M (1997) Comparison between cardiac output ...
The mitral valve area was determined by the Gorlin formula, and R and T were measured from the pressure tracings recorded at cardiac catheterization. The degree of correspondence between the equation tested and the measured cardiac output as determined by the Fick principle technique is characterized...
Fick equation (cardiac output formula) The most common formula used for determining the cardiac output is the Fick equation. It states that: CO=VO2 / (Ca−Cv)CO=VO2 / (Ca−Cv) where: VO2VO2 stands for the oxygen consumption of pure gaseous oxygen (in mL/minute); CaCa is the co...
Although cardiac output (CO) by pulmonary artery catheterization (PAC) has been an important guideline in clinical management for more than four decades, s
Cardiac output (CO) and the derived cardiac index (CI) are cornerstones of the hemodynamic evalution allowing pulmonary vascular resistance (PVR) calculation and risk stratification. According to the current European Guidelines, CO should be assessed by the direct Fick method or thermodilution (TD)....
