Fig. 2

Ocular and cerebrovascular time responses during a head-down tilt maneuver from 80° HUT to 6° HDT. Symbol p denotes pressure, Q is flow rate, and t is time. CBF and pdvs a indicate cerebral blood flow rate and dural venous sinus pressure, respectively. pdm,l and Qdm,l b indicate left distal middle cerebral artery blood pressure and flow rate. pccap, pcv, and Qcv c indicate cerebral capillary and venous pressures and cerebral venous flow rate, respectively. pMCA,l and QMCA,l d indicate left middle cerebral artery blood pressure and flow rate. pa,eye and pv,eye e indicate arterial and venous pressure at the level of the eye, while pICA,l and QICA,l f indicate left internal carotid artery blood pressure and flow rate, respectively. Thick lines represent the beat-averaged signals of the corresponding time series, which are depicted with thin lines.
