Temporal evolution of dynamic cerebral autoregulation parameters during experimental sepsis. Lxa (a, b), TFA gain (c, d), and phase (e, f), and of mean arterial pressure (g, h) in sepsis vs. sham (a, c, e, g) and septic shock (b, d, f, h). No difference was observed between the sepsis and sham groups but a progressive increase in Lxa, TFA gain, and a progressive decrease in TFA phase was observed in the septic shock group, indicating progressive loss of dCA. N/A = not available data, due to coherence values below significance (see the “Materials and Methods” section). Data are presented as median ± mean absolute deviation. *p < 0.05; **p < 0.01
