Abstract
A breath analyzing and training assembly for detecting CO2 concentration in the breathing gas of a user, includes a selective colorimetric CO2 detector having a detector surface which rapidly and reversibly changes color with CO2 concentration, when exposed thereto, and an adapter including: a docking part for receiving a mobile unit including an image capturing element, a display, and a processing element, the docking part configured to position the image capturing element in a fixed relation to the colorimetric detector, such that the image capturing element captures images of the detector surface; a detector holding part for receiving the colorimetric detector; a conduit for leading breathing gas to and from the user such that part thereof passes the detector surface; wherein the processing element measures CO2 concentration changes in the breathing gas by identifying color changes of images of the detector surface captured by the image capturing element.
