Through spirometry, which implies that you breathe in and out through a little pipe that is connected to a computer, conclusions regarding possible lung diseases can be drawn. In that way it is possible to check whether respiratory dysfunctions are present during breathing .This examination can be complemented by a medicated test, through which the lung function is checked before and after intake of a pill. In this way, the precise dosage for further intake of the pill can be directly determined. Anamnesis and lab results in combination with spirometry will determine if you have a chronic lung disease or an acute lung dysfunction.
