Breathing is the most overlooked vital sign in the human body. Respi.AI decodes every breath with flexible sensors and AI.
每一次呼吸都留下波形。大多数时候，这些波形没有被记录，也没有进入长期数据系统。Respi.AI 关注的不是单次检测，而是连续呼吸信号如何被稳定采集、结构化分析，并在真实世界场景中持续回流。
Every breath leaves a waveform. Most of the time, these waveforms are not recorded and never enter a long-term data system. Respi.AI is not focused on a single test; it focuses on how continuous respiratory signals can be captured reliably, analyzed structurally, and fed back from real-world settings over time.
呼吸是人体唯一一个既可以自主控制、又可以在无意识状态下自动运行的生命体征。它不像心率那样有明确的一次心跳周期，也不像血压那样是一个间歇测量值。呼吸是连续的——每一次吸气到呼气构成一个完整波形，而整晚的睡眠呼吸是数万个这样的波形首尾相连。
但在现有的医疗和消费级产品中，呼吸数据大多数时候是碎片化的。血氧仪只能间接反映血氧变化（这是呼吸暂停的结果，滞后 15–30 秒），智能手表和戒指依赖光电传感器推算，无法直接识别呼吸暂停事件的起止时间和类型。PSG 多导睡眠图虽然精确，但受限于医院场景，无法进入家庭长期使用。
Respi.AI 的判断：如果呼吸暂停是原因，血氧下降是结果，那么测量结果只能告诉你事情发生了，测量原因才能告诉你它是什么。这是柔性传感器直采呼吸信号的根本逻辑。
Respiration is the only vital sign that can be both voluntarily controlled and autonomously regulated. Unlike heart rate or blood pressure, breathing is continuous — every inhale-exhale cycle forms a complete waveform, and a full night of sleep contains tens of thousands of such waveforms. Yet in existing medical and consumer products, respiratory data remains fragmented. Pulse oximeters only reflect oxygen changes (a lagging result of apnea, 15–30 seconds behind); smartwatches rely on PPG estimation and cannot identify apnea onset or type. PSG is accurate but confined to hospital settings. Respi.AI's core insight: if apnea is the cause and oxygen desaturation is the result, measuring the cause tells you what happened — not just that it happened.
Respi.AI 的技术体系由三个核心模块构成：柔性传感器负责信号采集，PSG 金标准比对负责验证精度，AI 算法模型负责将原始波形转化为结构化指标。三者形成闭环。

PSG 多导睡眠图作为呼吸暂停模型验证阶段的临床金标准参照。在注册认证临床试验中，Respi.AI 传感器信号与 PSG 同步采集，由注册医师进行双盲标注，最终验证准确率 97.35%、灵敏度 98.21%、特异度 94.87%。
PSG polysomnography served as the clinical gold standard reference during model validation. In the registration clinical trial, Respi.AI sensor signals were acquired simultaneously with PSG, double-blind annotated by registered physicians, yielding 97.35% accuracy, 98.21% sensitivity, 94.87% specificity.
将连续呼吸波形转化为结构化指标。当前落地的第一个模型是睡眠呼吸暂停检测模型，输入传感器原始波形数据，输出呼吸暂停事件的逐秒识别：事件起止时间、类型（阻塞性 / 中枢性）和 AHI 计算。未来将基于持续回流的真实世界数据训练更多呼吸算法模型。
Converts continuous respiratory waveforms into structured metrics. The first deployed model is the sleep apnea detection model — input: raw waveform data; output: per-second apnea event identification (onset, type: obstructive/central, AHI computation). Future models will be trained on continuously returning real-world data.
Respi.AI 的长期资产不是狒狒贴这个单一硬件设备，而是数据回路：传感器在家庭场景中持续采集真实世界呼吸数据，经用户授权后回流研究系统，用于训练和迭代更多呼吸算法模型。模型的精度提升反过来增强产品的临床价值，吸引更多用户使用，产生更多数据。
Respi.AI's long-term asset is not a single hardware device, but the data loop: sensors continuously capture real-world respiratory data in home settings; with user authorization, this data flows back to the research system to train and iterate more respiratory algorithm models. Improved model precision enhances clinical value, attracting more users and generating more data.
这意味着每一台售出的狒狒贴，不只是完成一次监测任务，而是在为整个呼吸数据系统贡献新的信号。随着用户规模增长，数据规模和多样性同步增长，模型的泛化能力持续增强。这不是一个静态产品的逻辑，而是一个动态数据系统的逻辑。
This means every FeiFei Patch sold does not merely complete a single monitoring task — it contributes new signals to the entire respiratory data system. As the user base grows, data scale and diversity grow in parallel, continuously enhancing model generalization. This is the logic of a dynamic data system, not a static product.
Respi.AI 的长期资产不是单一设备，而是数据回路。
这也是狒狒贴在 Respi.AI 中的位置：它不是一个孤立产品，而是呼吸数据系统的入口。
Respi.AI's long-term asset is not a single device, but the data loop. FeiFei Patch is not an isolated product — it is the entry point to the respiratory data system.
