Obstructions in the Nose and Their Influence on the Pulmonary Functions

Abstract

1. Rhinomanometry is a method of measuring the nasal cavities by means of the pressure variations in the rhinopharynx during normal respiration.

2. Rhinomanometric examinations give information on the size of the nasal cavities and the activity of the turbinates as well as on the resistance in the nasal cavities during inspiration and expiration.

3. The “mask test”, during which respiration is exposed to mounting resistance, gives information on the patient's ability to compensate for an obstruction by adjusting the method of ventilation.
