The Oscillating Component of the Internal Jugular Vein Flow: The Overlooked Element of Cerebral Circulation

Table 1

Time period for jugular venous pulse (JVP) and spectral Doppler (SD) periodic diagram is reported for two healthy subjects together with the time averaged internal jugular vein (IJV) cross-sectional area (CSA) and the wave propagation velocity .

Subject	JVP period (s)	SD period (s)	(cm^2)	(m/s)
1	0.90	0.95	0.25	1.6
2	0.91	0.88	1.25	2.6
