ABSTRACT
Objective To analyze the flow spectra of in ternal jugular vein (IJV) in healthy adults by pulsed Doppler ultrasonography. Methods IJV flow velocities in 120 healthy volunteers were recorded during cardiac and respiratory cycles respectively with the transducer placed in cervical region view. Results In healthy subjects, IJV waveforms were composed of one reverse wave A and two forward waves S and D during cardiac cycle. The flow velocities of wave S [( 27.17 ? 19.88 )cm/s vs ( 19.04 ? 14.26 )cm/s] and wave D [( 17.43 ? 12.78 )cm/s vs ( 12.70 ? 10.57 )cm/s] were quicker during inspiration than those during expiration (P 0.05 ]. The velocities of wave S and wave D in the group aged over sixty years old were lower than those in the group aged between 20-60 years old(P
