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.

thermodilution

[-dilyo̅o̅′zhən]
a method of cardiac output determination. A bolus of solution of known volume and temperature is injected into the right atrium, and the resultant change in blood temperature is detected by a thermistor previously placed in the pulmonary artery with a catheter. Also called thermal dilution.

(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.

thermodilution

a technique for measuring size of a fluid-filled cavity by injecting a very cold sample of known volume and by measuring the change in temperature of the whole, assessing the degree of thermodilution, and hence the total volume of the cavity.
