Trends over time of the Neurological Pupil index (NPi) during episodes of sustained elevated intracranial pressure (ICP). Line graphs illustrating trends over time of the NPi (blue line) during 43 episodes of elevated ICP (gray line). Data are mean ± standard deviation of a total of 172 paired ICP-NPi measurements; **p < 0.001 for pairwise comparisons of baseline ICP and NPi values (6 h previous to ICP max [red arrow]) with Ti (≈ − 4 h), Tii (≈ − 2 h), ICP max, and NPi min, respectively (time 0)
