✦ Synopsis
Qunntitat i v t ~ hlood flow measurements were performed on 37 normal lower limbs with ii 128-channc4 digital pulsed Doppler {MDPD) system. The evolution of mean flow cQM 1, peak systolic flow CQS). diastolic flow (QD), and prograde stroke volume (PSV) was observed at rwt. during postocclusive reactive hyperemia t PORH), and at 1-. 2-, and :I-min intervals. ' The QM at rest was 2.9 + . 1.1 ml/s; PORH induced a fourto fivefold increase 111 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 signitici~ntly higher after 3 min To provide a better description of the hyperemic response. we d s o dudied the evolution of the pulsatility index as applied the flow curve (PIQI. Similarly. the systolic amplitude index (SAI! is presented. Our study demonstrates that pulsed Doppler techniques can be used for noninvasive quantitative assessment of hlood flow at rest and during PORH. The values obtained on normal subjects provide basr-line data for liirther investigation of pathological conditions. Indexing Words: Pulsed Doppler .
