Fig. 3From: Continuous bladder urinary oxygen tension as a new tool to monitor medullary oxygenation in the critically illUrine oxygen tension (PuO2) across time during Intervention H (target pump flow of 3.0 L/min/m2 and mean arterial pressure (MAP) of 80 mmHg) and Intervention N (target pump flow of 2.4 L/min/m2 and MAP of 65 mmHg). Each box represents the interquartile range (IQR) for the 20-secondly median values across patients, with lines out to \(\pm\) 1.5 \(\times\) IQR. Dots represent outliers. Mixed model for repeated measures showed statistical significance for group and time interaction (P < 0.001). Differences in PuO2 between the intervention groups, adjusted for repeat measurements, showed statistically significance after approximately 17 min (marked *). Reproduced from Hu et al.
