There are several contributing factors for these variations: metabolism, blood flow, tissue perfusion, and motion.
This figure clearly indicates that the resulting temperature is dominated by tissue perfusion.
Thus, the distribution of temperature is more strongly related to the presence of tissue perfusion.
They also recommended that one or all of the above markers of tissue perfusion be corrected to normal range within 24 hours after injury.
Tables 4and 5demonstrate that the changes in the electric field are not related to tissue perfusion.
For the case where temperature-dependent conductivity is applied in the absence of tissue perfusion, the current density increases 120%.
When tissue perfusion is accounted for, the areas corresponding to the proximal edge and the distal tip experience the most change.
At temperatures near 100 C, we see differences of approximately 5% between models that include and exclude tissue perfusion.
In those with poor tissue perfusion, boluses of isotonic crystalloid solution should be given.
This is more likely following infarction when cardiac output may be reduced and therefore tissue perfusion impaired.
