Carbon Dioxide Sensor to be Optimized for Medical Capnography Applications

Gas Sensing Solutions Ltd (GSSL) in conjunction with project partners Wide Blue Ltd (WBL) (project leader) and Cambridge Respiratory Innovations Ltd (CRIL) have secured a Technology Strategy Board (TSB) Collaborative Research & Development Project from the recent Photonics in Healthcare call. The project is valued at £748,000 UK. This project aims to develop a low cost respiration rate monitor & capnometer, based on GSSL patented non-dispersive infrared fast response infrared sensor, sensing exhaled Carbon Dioxide and to trial demonstrators in various clinical settings. Respiration rate and exhaled carbon dioxide (CO2) concentrations are known to be key measures in the evaluation...

Advantages of Solid State NDIR Sensors White Paper

Dr. Des Gibson(CEO) and Calum MacGregor(Operations Director) at GSS have published a technical document on the advantages of Solid State NDIR sensors compared to conventional NDIR sensors especially when used in applications for wireless and portable devices. The solid state NDIR sensors have an ultra-low power requirement and fast switch-on time which have been proven to be ideal in battery and energy harvesting applications. GSS CO2 sensors are currently available in the following ranges: COZIR Ambient: With measurement ranges of 0-2,000ppm, 0-5,000ppm and 0-1%, ambient CO2 sensors are suitable for applications such as HVAC, IAQ, LEED, horticulture and building control....

Measuring CO2 in Exhaled Breath to Help Save Lives

Capnography is the measuring and monitoring of the carbon dioxide levels in exhaled breath. In healthy individuals, the difference between the CO2 exhaled and CO2 levels in arterial blood are proportional. Therefore, by monitoring the waveform of CO2 levels on a capnogram (an electronic capnography monitor) over time, medical personnel like anesthesiologists or paramedics can use the information to monitor a patient. Sudden changes in end-tidal CO2 (ETCO2, the level of carbon dioxide released at the end of expiration) may signify changes in a patient’s heart or lung functions. Non-dispersive infra-red (NDIR) CO2 sensors are at the heart of virtually...
