Capnography is the measurement of CO2 at the end of expiration, used in medical applications. This measure is expressed in fraction or pressure. It provides information on the frequency and amplitude of breathing. It allows the diagnosis and precise quantification of tachypnea, bradypnea and especially ventilatory arrhythmias.
The monitoring of the CO2 level in the ambient air is essential. Indeed, a too high rate of CO2 in a space can be harmful for the health of the people who is there. On average a room should contain between 350 and 2500 ppm of carbon dioxide, however it is recommended to maintain this rate below 1000 ppm to promote well-being, concentration and avoid headaches and drowsiness.
The emission of carbon dioxide (CO2) is a natural process that occurs during fermentation, particularly during alcoholic fermentation. CO2 is a by-product of the decomposition of sugars by microorganisms, such as yeast, which convert the sugars into alcohol and CO2. CO2 is therefore produced in significant quantities during the fermentation process.
The analysis of CO2 in the exhaled air allows to know how the metabolism works. Indeed, the body generates more CO2 when it eliminates carbohydrates than lipids. By analyzing the concentration of CO2 in the exhaled air, it is possible to know what the body eliminates more quickly and therefore to adapt our diet in order to lose weight or to get back into shape.
On fertile days, the level of carbon dioxide in the women breath decreases. To determine those days, women have to do is breathe into our OCIEngine CO2 sensor. The exhaled air sample is exposed to infrared radiation passing through the sensor’s measuring cell. The CO2 molecules in the breath absorb some of the IR radiation. The detector is equipped with an optical filter optimized for the gas of interest and detects any difference in the carbon dioxide transmission. The absorption of radiation due to the CO2 molecules thus allows to determine the concentration of the gas.
