Fig. 2 Calibration curve shows pressure changes in the air chamber with water injected into calibration bag in increments of 50 ml.

Fig. 3 Diagrammatic representation of typical recording of volume changes during standard sequence of postural changes and exercise. Patient in supine position with leg elevated 45 degrees (a); patient standing with weight on nonexamined leg (b); single tiptoe movement (c); ten tiptoe movements (d); same as in (b)/(e). VV = functional venous volume; VFT = venous filling time; VFI = venous filling index; EV = ejected volume; RV = residual volume; EF = ejection fraction; RVF = residual volume fraction.

Fig. 4 Typical recording of effect on venous pressure of 10 tiptoe movements. P = pressure; T = time; R = refilling; RT90 = time taken for 90% refilling; AVP = ambulatory venous pressure at the end of exercise.

Fig. 5 Functional venous volume (VV) measurements in (A) absolute and (B) normalized units (N = normal limbs; SVI = limbs with superficial venous incompetence; DVD = limbs with deep venous disease). Data from individual limbs, with median and 90% tolerance levels, are shown.
