Figure 1

Correlation of urine flow rate variability (UFRV) (A) and urine flow rate (UFR) (B) with mean arterial pressure (MAP) at the time of new septic events (black arrows) and following initial fluid resuscitation (red arrows). Note that the UFRV and the UFR decreased progressively in parallel with the falling MAP and rose again after the administration of fluids

Laboratory and clinical data of the 50 study group patients (mean ± SD)_

TIME1

TIME1 – vital signs during the 3 hours following admission to the ICU; TIME2 – vital signs 9 hours after the septic event.

TIME2

TIME1 – vital signs during the 3 hours following admission to the ICU; TIME2 – vital signs 9 hours after the septic event.

A p value of less than 0.05 is considered to be statistically significant.
