Google AI 用普通智能手表无袖带检测高血压
原标题：Google's AI detects high blood pressure from a regular smartwatch without a cuff
AI 摘要
Google Research 开发出一种 AI 方法，仅利用智能手表内置的脉搏和运动传感器即可检测高血压迹象，无需血压袖带进行校准。该神经网络从近 50 万小时的传感器数据中自监督学习脉搏与心跳模式，再对多日数据取平均以估算高血压概率。在 196 人、五个美国研究点的研究中，该方法识别出 65.8% 的高血压患者，高于诊室标准测量的 55.3%。相关发现已并入 Google Health 应用的血压趋势功能，但仍属研究项目，不能替代诊断。

Google's AI detects high blood pressure from a regular smartwatch without a cuff A Google Research AI can detect signs of high blood pressure using a regular smartwatch, with no blood pressure cuff needed for calibration. The AI relies on two sensors already built into modern watches—a pulse sensor and a motion sensor—according to a Google blog post. The study was published in Nature. A neural network learned from nearly 500,000 hours of sensor data by comparing short segments and figuring out w
