Fig. 5

Blood and cerebrospinal fluid (CSF) flow rates aligned with the physiologic signals for the three types of breathing. The flow rate of Internal Carotid Artery (ICA) is represented in red, that of Internal Jugular vein (IJV) in blue and that of cerebrospinal fluid (CSF) in black. The band-pass filtered (BPF) flow rates are superimposed to the respective flow rates for showing their correspondence with respiratory signals. The whole acquisition (60 s) is shown. The effect of inspiration (in, green arrows) on the flow rates are underlined with arrows in the deep breathing, where the respiratory influence is the greatest
