摘要

背景:局部脉波速度(C)的压力依赖性搏动内变化的临床意义近年来逐渐得到重视。虽然已有报道的方法需要从单个位置测量动脉压力和直径来评估心跳内C的变化，但我们提出了一种无图像的快速超声设备，该设备通过捕获动脉近端两个位置的直径波形来实现这一目标。方法:对8名血压正常的受试者(26±4岁)进行功能评估。通过短时间的中度下体负压干预扰动血压，测量颈动脉舒张压和80%峰值压对应的[2]、CD和CF脉波速度。使用人用NIBP系统(ADInstruments, India)监测连续压力。

P.41 Measurement of Pressure-dependent Intra-Beat Changes in Carotid Pulse Wave Velocity using Image-Free Fast Ultrasound

Background: The clinical significance of pressure-dependent intra-beat changes in local pulse-wave velocity (C) has recently come to light [1]. While reported methods require arterial pressure and diameter measurements from a single site to assess intrabeat changes in C, we present an image-free fast ultrasound device that performs this by capturing diameter waveforms from two proximal locations on an artery.. Methods: The functionality was assessed on eight normotensive participants (26 ± 4 years). By perturbing blood pressure through a short duration moderate lower body negative pressure intervention [2], CD and CF pulse wave velocities corresponding to diastolic and 80% of peak pressure were measured from the carotid artery. Human NIBP system (ADInstruments, India) was used for monitoring continuous pressure.
