“…Thus, it appears that the restoration of resting values of phasic flow components after PORH is sequential: (1) restoration of mean flow (QM) and systolic flow (QS) occurs within 1 min, and (2) the reverse diastolic flow (QD) reappears after 1 min, but base-line values are reached only after 2 min.…”

Quantitative blood flow measurements were performed on 37 normal lower limbs with a 128-channel digital pulsed Doppler (MDPD) system. The evolution of mean flow (QM), peak systolic flow (QS), diastolic flow (QD), and prograde stroke volume (PSV) was observed at rest, during postocclusive reactive hyperemia (PORH), and at 1-, 2-, and 3-min intervals. The QM at rest was 2.9 +/- 1.1 ml/s; PORH induced a four- to fivefold increase in QM and PSV secondary to a slight increase in QS and the disappearance of the reverse protodiastolic component of resting flow. Reverse flow was restored after 1 min. Both QS and QD returned to resting values after 2 min, whereas QM remained significantly higher after 3 min. To provide a better description of the hyperemic response, we also studied the evolution of the pulsatility index as as applied the flow curve (PIQ). Similarly, the systolic amplitude index (SAI) is presented. Our study demonstrates that pulsed Doppler techniques can be used for noninvasive quantitative assessment of blood flow at rest and during PORH. The values obtained on normal subjects provide base-line data for further investigation of pathological conditions.

A duplex ultrasonographic system was used to examine the common femoral artery in left and right legs of 49 fit young men and 15 fit young women, to find out the normal blood flow in the human leg during rest. By this method the diameter of the vessel and the time average velocity could be measured and the blood flow calculated. Each person underwent three examinations of each leg after 10-min rests. The average diameter of the common femoral artery was 91 +/- 10 mm (95 mm in the men and 80 mm in the women), the average blood flow 226.2 +/- 82.1 ml/min (235.9 ml/min in the men and 189.6 ml/min the the women). Compared with other methods used for femoral blood flow studies, we found the duplex ultrasound system reliable, non-invasive, and infinitely repeatable. This method therefore also seems appropriate for clinical studies. In a few tests carried out in trauma patients we found a pronounced increase in blood flow after a few days, and also an expected increase in a patient with arterio-venous fistula and an expected decrease in one with arterial occlusive disease. These examinations were performed to establish a method for further examinations of long-lasting blood flow alterations in trauma patients, which will be reported in another paper.
