description Devices and methods are provided for breath gas analysis when determining the difference in the concentrations of at least one gas in the exhaled breathing air on the one hand and in the ambient air on the other hand. The device may include at least one gas sensor, by means of which the concentration of a gas can be determined, and a line system, through whose lines the exhaled air to be examined, the ambient air and a calibrating gas can be selectively pumped to the gas sensor. The method may include feeding ambient air; feeding calibrating gas to the gas sensor; feeding exhaled air to the gas sensor; feeding calibrating gas to the gas sensor again; and feeding exhaled air to the gas sensor again.
