Web25 de out. de 2024 · To measure a pulse wave on the radial artery, previous studies suggested a multi-channel pressure sensor arranged in a grid to accurately position the sensor in the center of the radial artery [15,16].However, since the individual pressure sensors that make up the multi-channel pressure sensor must be present on the radial … WebAn elevated velocity with a normal waveform throughout the vertebral artery can be due to compensatory flow in cases of high-grade stenosis or occlusion in the carotid circulation. If both common carotid arteries are occluded, vertebral artery velocities will be elevated bilaterally, often quite dramatically (Fig. 11A, 11B, 11C, 11D).
