Putting a patient in 45 degrees , marking the sternal angle, identify the  oscillating venous column,  measuring   the vertical distance  etc . . .

Now in 2010 , with bedside hand-held echo one can rapidly  rule out an elevated  central venous pressure by imaging the jugular vein directly . Here is an article from American heart  journal
