A combination of cooling systems for the injectate used in thermal dilution cardiac output measurements is shown to quickly cool the thermal indicator to a low homogeneous temperature. The variability of the physical constants characterizing the catheter thermistors are found to be adequately compensated for by the calibration resistors incorporated in the catheters. The calibration resistors are found to have a magnitude approximately 20 times the differential resistivity of the thermistors and this linear relationship is validated on theoretical grounds.
