The complete system for functional diagnosis of nasal breathing
  • Rhinomanometry and Rhinoresistometry
  • Acoustic Rhinometry
  • Long-term Rhinoflowmetry


Rhinomanometry and Rhinoresistometry
The RHINO-BASE offers as a key element the Rhinoresistometry, a further development of active anterior Rhinomanometry. Nasal flow rate is measured using a breathing mask. The filter between measuring nozzle and face mask is replaceable. Choanal pressure is measured using an adhesive nasal adapter. An additional benefit is that the micro pressure sensors can be connected directly to the breathing mask, thus minimizes measurement errors. Nasal flow resistance can be objectified reproducibly using Prof. G. Mlynski’s (University Greifswald, Germany) highly complex analytical software which has been developed and improved over many years. This is the basis for differential diagnosis of possible causes of nasal obstruction like constriction, inspiratory nasal wing collapse or pathological turbulence.


Acoustic Rhinometry
The Acoustic Rhinometry is a powerful instrument for measuring the nose airways. It uses an acoustic impulse to measure the cross-sectional areas over the distance from the outer nostril. These cross-sectional areas let the examiner know weather or not there are narrow points in the airways which can be a problem for a patient’s respiration. It is easily applied, reliable, non-invasive and well accepted by patients. Even assessment of children is performed without problems. The RHINO-ACOUSTIC measurement system consists of the measuring software and the RHINO-BASE central which contains the data acquisition hardware for the measuring purposes. Additional items are the acoustic measuring probe, a long calibration pipe and the nose adapters.


Long-term Rhinoflowmetry
Rhinometric measurements are limited to assess the nasal airway only in a short period of time in which the measurement is performed. Many patients report about functional complaints at various time periods. In consequence, a diagnostic tool to gain more insight into the respiratory function during conditions of normal life is necessary. The RHINO-MOVE, a portable measuring system, enables breathing to be registered over a 24-hour period, with separate records for each side of the nose. The synchronous registration of the heart rate enables an evaluation of the physical strain. Once measuring is complete, the saved data are transferred to a laptop and analysed with the RHINO-SYS software. Thus, for the first time, the nasal cycle and its disturbance can be recorded under a patient’s daily life condition.
