[Power curves in rhinomanometry].

In diagnostic evaluation of the nose and allergology, the transnasal pressure delta p and the volume flow V is measured during breathing. It is shown that information is lost when measurements are represented form of a rhinomanogram. It is proposed using the measurements to derive the power during breathing and the mean volume flow of a breathing cycle. At a variable amplitude of breathing, the respiration power can be represented as a function of the mean air flow. For this purpose the software of available rhinomanometers merely has to be modified.

[Nasal cycle using rhinomanometric measurements].

Observations on cyclical variations in the nasal resistance were made using active anterior rhinomanometry. About 80% of 40 healthy individuals showed a nasal cycle with a mean period of 2.5 h. Measurements were made during a 8 h at intervals of 30 min. Quantitative values for the variations of the flow volume V1.5 at 1.5 hPa are given and discussed.

[Rhinomanometric measurements in obstructed nasal respiration before and following rhinosurgical interventions].

355 patients with nasal obstruction caused by different disease were treated by various nasal operations. Active anterior rhinomanometry was performed before and after operation, both before and after decongestion of the nasal mucosa. 254 patients were reassessed 6 to 9 months later. On average an increase of nasal airway was achieved from V 1.5 = 0.46 1/s before operation to 0.74 1/s after operation (before decongestion) and from V 1.5 = 0.55 1/s before operation to 0.83 1/s after operation (after decongestion of the nasal mucosa). The decongestion effect and the differences between the better worse nasal cavities showed a significant decrease after operation. Rhinomanometric evaluation of the various nasal operations is presented for patients with nasal blockade caused by various diseases.
