Thermal-dilution technics.

• .All thennal methods for the study of the circulation depend upon the induction of a change in the heat content of! the blood stream. As a result of the change, a particular time-dependent spatial distribution of temperature is developed in the blood according to the manner in which the change is brought about and as a function of the prevailing pattern of blood flow. In a general sense, any ...
