Cardiac output is one of the most valuable hemodynamic parameter. It is measured commonly with intravascular pressures by pulmonary artery catheterization technique. The cardiac output itself is measured by dilution of thermal marker method (thermodilution), which is not resistant for various disturbances. In this paper the influence of blood temperature on metrological properties of thermal dilution method was described.
