A technique is described for measuring digital and segmental systolic blood pressure by laser Doppler fluxmetry. A transparent plastic capsule contains the small sphygmomanometer cuff connected to a Statham manometer. It has a hole for positioning the probe at the very tips of fingers or toes. An advantage of this method over the conventional strain-gauge technique is that it is better suited for determinations at short digits where it is difficult to fix a strain-gauge. Moreover, it allows consecutive pressure and flux measurements at almost identical distal sites without moving the probe. The correlation between the values obtained by the conventional and laser Doppler procedures are excellent. Systolic pressures were determined on 14 extremities of 7 healthy controls and on 20 extremities of 14 patients with intermittent claudication due to peripheral arterial occlusive disease. Measuring sites were the upper arm, forearm, index finger, ankle and big toe. The values agree well with those obtained earlier by the strain-gauge technique.
本文描述了一种通过激光多普勒血流仪测量手指和节段收缩压的技术。一个透明塑料胶囊内装有与斯塔瑟姆压力计相连的小型血压计袖带。它有一个孔，用于将探头定位在手指或脚趾的尖端。这种方法相对于传统应变片技术的一个优点是，它更适合于在难以固定应变片的短手指上进行测量。此外，它允许在几乎相同的远端部位连续进行压力和血流测量，而无需移动探头。传统方法和激光多普勒方法获得的值之间的相关性非常好。对7名健康对照者的14个肢体以及14名因外周动脉闭塞性疾病导致间歇性跛行的患者的20个肢体进行了收缩压测定。测量部位为上臂、前臂、食指、脚踝和大脚趾。这些值与早期通过应变片技术获得的值非常吻合。
