thermodilution

thermodilution

 [ther″mo-di-loo´shun]
a method of measuring ventricular blood volume and cardiac output. A series of 3 to 5 injections of a solution of known temperature is followed by calculation by a computerized sensor or thermistor of the average changes in temperature.

ther·mo·di·lu·tion

(ther'mō-di-lū'shŭn),
Reduction in temperature in a liquid that occurs when it is introduced into a colder liquid; the volume of the latter liquid can be calculated from the amount of rise in its temperature.

When the initial treatment does not improve the targets for therapeutic destination, advanced critical hemodynamic monitoring, such as transpulmonary thermodilution or pulmonary artery catheterization, is required and should be performed.
The left jugular vein was cannulated for fluid and drug administration and the left femoral artery for the measurement of mean arterial pressure (MAP), heart rate (HR) and cardiac output (CO) by transpulmonary thermodilution (PICCO Catheters; PULSION Medical Systems, Feldkirchen, Germany).
A significant correlation was observed between bioimpedance and the thermodilution indicator method.

A 5F catheter (PV2015L20, Pulsion Medical Systems, Germany) was inserted into the right femoral artery for thermodilution measurements and pulse contour analysis and connected to the Infinity[R] PiCCO SmartPod[TM] XL monitor (Infinity Delta XL, Drager).
However, owing to the invasiveness of the Fick technique and the dye injection method, they have been replaced by other more modern and simplified techniques including thermodilution techniques, lithiumdilution, bioreactance, and Doppler technique or echocardiography [52, 53].
However, it is not just the risk of arrhythmias which, indeed, is increased, that should be held in mind, but also that thermodilution measurements can be altered.
