We have three instruments that provide a complete study of nasal structure and performance and can be used together or individually to quantify nasal conditions
The Acoustic Rhinometer offers a very rapid and non-invasive examination of the nasal cavity through a nosepiece using a sound pulse technique. It quantifies nasal airway structure in either or both nostrils and offers a static profile of nasal structure during a breath hold maneuver. This indicates where the obstructions are and how severe they are in real units (cm and cm2)
The Rhinomanometer calculates nasal airway resistance by measuring nasal flow and the pressure producing that flow. It quantifies nasal airways resistance in either or both nostrils and offers a physiologically normal, dynamic measurement function. This indicates whether the patient’s airway is within the normal range, or out with it, and can indicate the possibility of a number of medical conditions, such as physical obstruction, allergic rhinitis, chronic sinusitis and septum deviation.
The Rhinospirometer allows the measurement of portioning of airflow between two nasal passages and provides a Nasal Partitioning Ratio. Used with subjects who have a Septal Deviation, clinical work has identified a key ratio, above which subjects are likely to benefit from surgery and below which, they are unlikely to benefit from surgery. It is therefore possible to avoid unnecessary trauma for the patient and save the hospital the costs involved in an operation.
