Measuring the concentration of carbon dioxide during expiration

20th September 2017

Posted By Paul Boughton


Capnography is a non-invasive method that measures the concentration of carbon dioxide during expiration (EtCO₂).

Initially used in hospital surveillance and emergency care, capnography is rapidly becoming popular in medical practices and homecare medicine.

The trend to miniaturise such modules emphasises the advantages of the Axetris MEMS-based broadband infrared (IR) sources for NDIR gas detection.

Axetris offers solutions by providing a portfolio of IR sources with adapted reflectors and optionally mounted optical windows.

Axetris' newly-released qualified EMIRS50 is specifically made for compact NDIR capnography sensors for high-quality CO2 monitoring.

Its high emission at 4.26μm and an integrated reflector that improves efficiency makes Axetris' infrared source EMIRS50 make the first choice when it comes to integrating it in capnography analysers.
