[Comparability of lung and nasal resistance. possibilities of comparison of rhinomanometry and bodyplethysmography (author's transl)].

Only a harmonical balance between the lung and nasal resistance garant an optimal respiratory mechanism. Therefore both resistances should not be judged separately. Up to now different methods of measurement of both resistance have been used. The substruction method has certain drawbacks in determining nasal resistance. On the other hand nasal resistance determined by rhinomanometry only becomes comparable to lung resistance if registered by a special simplified method. The problems of comparing quantitively both resistances are discussed and a solution is proposed.
