The colorimetric method for detecting CO2 in a durable way was originally conceived for visual indication of the presence of the gas to verify proper tracheal intubation.                     (A. Gedeon, P. Krill and C. Mebius: Anaesthesia 1994;49,798)

Mincor AB has a unique, new technology for measuring the concentration of CO2 in expired gas using an optical readout and software for quantitative color determination. It is simple, inexpensive and can accurately measure the end expiratory CO2 level and the respiratory rate.

The method was first described at the ASA meeting in New Orleans in 2014 with the poster below:
