Fig. 4. Proximal-to-distal arterial tree: pressures and flow rates in 1G supine and 0G conditions.

Time-series P(t), Q(t), $P^{\prime }\left(t^{\prime }\right)$, and $Q^{\prime }\left(t^{\prime }\right)$ at the extremes of the 1D arterial proximal-to-distal tree: ascending aorta and anterior tibial artery. Blue: supine 1G configuration on the Earth; red: 0G spaceflight configuration. NSD values for $Q^{\prime }$ and $P^{\prime }$, together with mean pressure ($\overline{P}$), mean flow rate ($\overline{Q}$), max pressure ($P_{\max }$), and pulse pressure (PP) relative variations between 1G and 0G configurations are reported in the panels.
