Correlations between all the variables analyzed at T0, T2 and T3 (a,b,c). Intensity of Red indicates Inverse Correlations,Blue indicates Direct. There is a greater direct correlation at T3 between the dose of Norepinephrine and the Resistance Index. The hypothesis that can be made to explain this is linked to the mechanism of Receptor Desensitization. Receptor Desensitization means that the dosage of Norepinephrine must be increased over time to produce the desired effect (MAP>65mmHg). This increase therefore determines, in addition to the desired effect, also an increase in side effects such as tachyphylaxis, vasoconstriction and therefore the increase of the Resistance Indices. -IR MES SUP= AMS;IR O right/left= CRA R/L; KIDNEY IR right/left= ARE R/L; IR snuff right/left=AR R/L ;NORA DOSE= Ne dose
