Respiration rate and exhaled carbon dioxide (CO2) concentrations are known to be key measures in the evaluation of patient health trends in both routine healthcare and emergency healthcare. However routine and reliable measurement of respiration rate is notoriously difficult to do. It is prone to false readings, outside influences and is therefore not considered reliable. Previous attempts have included the use of motion sensors, flow measurements or use expensive IR lasers and are prone to ergonomics concerns with product costs too high for widespread adoption and routine use. This project aims to develop a low cost respiration rate monitor & capnometer,based on patented non-dispersive infrared fast response infrared sensor, sensing exhaled carbon dioxide and to trial demonstrators in various clinical settings. This project aims to use unique patented low cost solid state mid-infrared light emitting diode/ photodiode detector combination and an optical waveguide to measure rates of exhaled CO2.The project involves a consortium of Wideblue Ltd, Gas Sensing Solutions Ltd and Cambridge Respiratory Innovations Ltd.

呼吸率和呼出的二氧化碳（CO2）浓度是评估常规医疗保健和紧急医疗保健中患者健康趋势的关键指标。然而，呼吸率的常规和可靠的测量是众所周知的困难。它容易出现错误的读数，外部影响，因此不被认为是可靠的。以前的尝试包括使用运动传感器、流量测量或使用昂贵的IR激光器，并且容易产生人体工程学问题，产品成本太高而无法广泛采用和常规使用。该项目旨在开发一种低成本的呼吸率监测仪和二氧化碳监测仪，基于专利的非色散红外快速响应红外传感器，感测呼出的二氧化碳，并在各种临床环境中进行试验演示。该项目旨在使用独特的专利低成本固态中红外发光二极管/光电二极管检测器组合和光波导来测量呼出CO2的速率。该项目涉及Wideblue Ltd，Gas Sensing Solutions Ltd和剑桥呼吸创新有限公司的联盟。
