Options for the continuous and non-invasive monitoring of blood pressure are limited. Cuff-based sphygmomanometers are widely available, yet provide only discrete measurements. The clinical gold-standard approach for the continuous monitoring of blood pressure requires an arterial line, which is too invasive for routine use. Wearable ultrasound for the continuous and non-invasive monitoring of blood pressure promises to elevate the quality of patient care, yet the isolated sonographic windows in the most advanced prototypes can lead to inaccurate or error-prone measurements, and the safety and performance of these devices have not been thoroughly evaluated. Here we describe validation studies, conducted during daily activities at home, in the outpatient clinic, in the cardiac catheterization laboratory and in the intensive care unit, of the safety and performance of a wearable ultrasound sensor for blood pressure monitoring. The sensor has closely connected sonographic windows and a backing layer that improves the sensor’s accuracy and reliability to meet the highest requirements of clinical standards. The validation results support the clinical use of the sensor.

连续和无创血压监测的选择有限。基于袖带的血压计广泛可用，但仅提供离散测量。持续监测血压的临床金标准方法需要动脉导管，这对于常规使用来说太侵入性了。用于连续无创血压监测的可穿戴超声有望提高患者护理质量，但最先进的原型中孤立的超声窗口可能导致测量不准确或容易出错，并且这些设备的安全性和性能尚未得到彻底评估。在这里，我们描述了在家中、门诊、心导管实验室和重症监护室的日常活动中进行的验证研究，这些研究对用于血压监测的可穿戴超声传感器的安全性和性能进行了验证。该传感器具有紧密相连的超声窗口和背衬层，可提高传感器的准确性和可靠性，以满足临床标准的最高要求。验证结果支持传感器的临床使用。
