Measurement of access flow by thermodilution: in vitro experiments

This abstract described in vitro validation (no in vivo studies yet, unfortunately) of a method of measuring access blood flow using thermodilution. The principle is the same as with the Transonics ultrasound dilution method, but instead of a dilution stimulus to the venous line blood, a cold stimulus is applied, and the amount of cold transmitted to a sensor on the arterial bloodline (after crossing the lines) can be used to compute access blood flow. Theoretically, all of these methods are infallible, but they depend on adequate mixing in the access segment between the needles. The advantages of this new method are that it can easily be adapted using the Fresenius BTM module, and requires no injections to produce the stimulus (the stimulus is provided by a step change in dialysate temperature).
