Figure Lengend Snippet: PSI in relation to perfusion and intracranial compliance. These GAMs illustrate the potentially non-linear relationships between PSI and ABP, ICP, AmpICP, and RAP. Each analysis was performed within physiologically relevant ranges: PSI 1–4, ABP 40–120 mmHg, ICP 0–40 mmHg, AmpICP 0–15 mmHg, and RAP 0.0 to + 1.0. AmpICP = peak-to-peak ICP pulse amplitude. ABP = Arterial blood pressure. GAM = Generalised additive models. ICP = Intracranial pressure. RAP = the correlation (r) between ICP amplitude and ICP
Article Snippet: Arterial blood pressure (ABP) was recorded from the radial or femoral artery (Baxter Healthcare, Deerfield, Illinois), with zero calibration at the level of the heart (2002–2015) and the tragus (2015–2022).
