Abstract
An apparatus for reporting accurate results in thermodilution by single pulmonary arterial catheterization procedures comprises an elongated multilumen catheter having a distally-placed thermistor and proximally-placed thermistor and a plurality of electrical sensing means connected to the thermistors. The proximal thermistor is so positioned as to be substantially totally immersed in the blood-injectate mixture to rapidly and accurately determine the temperature thereof. The use of two thermistors so placed provides highly accurate temperature data requiring substantially no correction.
