Rhinology
DIFRA is also active in rhinology with a high class rhinomanometer. Specially developped for research, the RhinoCeros is using a low resistance and linear flowmeter type "Fleish".
Keeping this advantage, RhinoCeros is now known as a standard for clinical rhinomanometry and also for research.
Rhinomanometry is a dynamic test that measures trans nasal pressure and airflow. By providing a display of the resistance to airflow through the nostrils, RhinoCeros gives you a better understanding of the patient's subjective feeling of nasal patency.
Nasal resistance is calculated by measuring the flow through the nose and also the pressure of force required to cause the airflow.
Because the nasal resistance is very low, the flowmeter need to have the lowest resistance as possible. To verify the quality of your flowmetre, it's easy : just put the mask on your face and breath once quickly and strongly. If you feel a suction on your face, that will say that your flowmeter has a big air resistance and this is not recommended for a good measurement of nasal flow.
There are two types of measurement of rhinomanometry: anterior rhinomanometry and posterior rhinomanometry. The RhinoCeros is able to do both !
The advantage of this test is that it can very accurately assess nasal blockage in the nose and difficulty in breathing due to other reasons. It also measures nasal blockage at normal breathing. However, the disadvantage is that it does involve expensive bulky equipment and requires staff to operate it.
