频繁的血压（BP）评估对于许多严重疾病的诊断和治疗至关重要，例如心力衰竭、肾衰竭、高血压和血液透析。目前的“黄金标准”血压测量技术需要完全阻断血流，当重复和频繁地进行评估时，这会导致不适并干扰正常活动。不幸的是，患有高血压或血液透析的患者通常必须每 15 分钟测量一次血压，持续 4-5 小时或更长时间。佩戴笨重且活动受限的设备的不适会影响他们的正常活动。在这项工作中，我们提出了一种名为 eBP 的设备，用于从用户耳内测量血压，旨在最大限度地减少测量对用户正常活动的影响，同时最大限度地提高其舒适度。eBP 具有 3 个关键组件：(1) 连接在耳内充气管上的光脉冲传感器，(2) 带有精细控制器的数字气泵，以及 (3) 血压估计算法 与现有设备相比，eBP 引入了一种无需阻塞耳内血流的新技术，从而减轻了用户的不适。通过对 35 名受试者进行的比较研究表明，eBP 的收缩压（高压值）和舒张压（低压值）的平均误差分别为 1.8 mmHg 和 -3.1 mmHg，标准偏差误差约为 FDA 的 AAMI 协议规定的可接受范围，该协议允许平均误差高达 5 mmHg 和标准偏差高达 8 mmHg。
Frequent blood pressure (BP) assessment is key to the diagnosis and treatment of many severe diseases, such as heart failure, kidney failure, hypertension, and hemodialysis. Current "gold-standard'' BP measurement techniques require the complete blockage of blood flow, which causes discomfort and disruption to normal activity when the assessment is done repetitively and frequently. Unfortunately, patients with hypertension or hemodialysis often have to get their BP measured every 15 minutes for a duration of 4-5 hours or more. The discomfort of wearing a cumbersome and limited mobility device affects their normal activities. In this work, we propose a device called eBP to measure BP from inside the user's ear aiming to minimize the measurement's impact on users' normal activities while maximizing its comfort level. eBP has 3 key components: (1) a light-based pulse sensor attached on an inflatable pipe that goes inside the ear, (2) a digital air pump with a fine controller, and (3) a BP estimation algorithm. In contrast to existing devices, eBP introduces a novel technique that eliminates the need to block the blood flow inside the ear, which alleviates the user's discomfort. We prototyped eBP custom hardware and software and evaluated the system through a comparative study on 35 subjects. The study shows that eBP obtains the average error of 1.8 mmHg and -3.1 mmHg and a standard deviation error of 7.2 mmHg and 7.9 mmHg for systolic (high-pressure value) and diastolic (low-pressure value), respectively. These errors are around the acceptable margins regulated by the FDA's AAMI protocol, which allows mean errors of up to 5 mmHg and a standard deviation of up to 8 mmHg.
