RhinoCycle | Long-term registration of nasal airflow - A standalone unit that do not work with the SRE2000.

A normal healthy nose has a cycle where the mucosa in one nostril is active, while the other is resting. After a certain amount of time, they change and the other nostril becomes active. It may vary how long time the mucosa is active from person to person. If the cycle is abnormal, this may cause respiratory problems.

Current methods for functional rhinological diagnostics (Rhinomanometry, Rhinoresistometry and acoustic Rhinometry) quantify the situation of the nose at the time of examination only. In clinical practice, patients often complain about temporary nasal obstruction, for example during the night. Additionally, discrepancy between conventional diagnostics, clinical symptoms and endoscopic findings can be seen. All currently used methods do not give insight into alterations by the nasal cycle or temporary nasal complaints.

RhinoCycle is a portable, battery powered device for long-term registration of nasal airflow developed to monitor the nasal cycle and is based on a method called "Rhinoflowmetry". The RhinoCycle software provides an excellent overview of the nasal cycle variations to support the final diagnosis. It is a complementary tool in addition to the established rhinological diagnostics. The system is ideal for home monitoring with few instructions from a professional. The patient can carry on with light to moderate activities and may sleep with the system.
