In this exploratory study, increasing PEEP from 5 to 10 cmH₂O was associated with a higher VII, while IRVF patterns and RRI showed minimal change.

As reported in the abstract
- Intrarenal venous flow (IRVF) patterns stable across PEEP levels; patients transitioning to a different IRVF pattern
- 3 (8.6%)
- Renal resistive index (RRI) did not change significantly with higher PEEP
- 0.005 (difference; 95% CI, −0.012 to 0.022)
