[Monofrequency oscilloresistometry--possibilities and limits of a non-invasive method for respiratory resistance measurement in calves].
The monofrequency forced oscillation technique (MFOT) has been found to be a simple, reproducible, fast and accurate method to carry out lung function testing in calves even under field conditions. If some technical as well as methodological requirements are taken into account, pulmonary or respiratory resistance can be assessed by means of the parameter oscillatory resistance (Ros). Furthermore, several Ros derived parameters are available for describing the functional status of the central bronchial system. Due to the low variability caused by methodological or intraindividual reasons, the MFOT represents a very qualified method for intraindividual studies. Comparing measuring results of different subjects, a higher biologically caused variance has to be taken into account.
