Percent changes of mean ICP and REG integral during 15 and 20 cmH2O PEEPs before first (1) and after first bleedings (2), and after second bleeding (3). Values are in percentage of their own baseline. Measurement was made at the highest values. Note that after 2nd bleeding REG values are negative, indicating that CBF AR is passive.
