Improving the accuracy of Lifelight First closer to standard-of-care vital sign technologies: experiments addressing signal processing and feature extraction challenges to help penetrate the clinical and home-monitoring market.

一家名为“xim”的南安普敦小公司正在开发Lifelight First（r），这是一种使用智能手机摄像头在40秒内测量心率、血压、血氧饱和度和呼吸频率的技术。Lifelight First使健康监测变得毫不费力，对于那些发现市场上现有设备（如血压袖带）疼痛或不方便的人来说非常有用。与血压袖带不同，血压袖带需要患者卷起袖子，这会让上臂较大的患者感到尴尬，并且紧紧地挤压您的手臂，有时会造成瘀伤，Lifelight First是完全无接触和无障碍的。Xim正在与国家物理实验室合作，使用来自Innovate UK Analysis For Innovators赠款竞赛的资金。他们为期10个月的项目的目的是改进Lifelight First的算法，使其能够像NHS目前使用的血压袖带，脉搏血氧仪和心率监测器一样好。这样，Lifelight First可以更快地在NHS内使用。

A small Southampton-based company called "xim" are developing Lifelight First(r), a technology that measures your heart rate, blood pressure, oxygen saturation and respiratory rate in just 40 seconds using a smartphone camera. Lifelight First makes health monitoring effortless and is useful for those who find existing equipment on the market, such as blood pressure cuffs, painful or inconvenient. Unlike blood pressure cuffs which require the patient to roll up their sleeves; cause embarrassment for those with larger upper arms; and squeeze your arm so tightly that sometimes they can create a bruise, Lifelight First is completely contactless and hassle-free.Xim are working with the National Physical Laboratory using funds from the Innovate UK Analysis For Innovators grant competition. The aim of their 10-month project is to improve Lifelight First's algorithms so that it can perform as well as blood pressure cuffs, pulse oximeters and heart rate monitors currently used by the NHS. That way, Lifelight First can be used within the NHS sooner.
