Measuring nasal function in aviators

The importance of nasal function in the overall health of man is well documented. The physiologic function of the nose is especially important in the harsh environment of military aviation. Present standards for evaluating nasal function in aviators are based primarily on subjective complaints and limited physical examinations. Rhinomanometry has been used for approximately 100 years for measuring nasal function. Otorhinolaryngologists have used modern rhinomanometric methods for the past 25 years. Rhinomanometry allows the measurement of airflow and pressure in the normal respiratory cycle through the nose. Present methods involve using a simple flow measuring device coupled with a pressure device to measure the pressure required to drive a given amount of air through the nose. Under current development are machines that will automatically measure the work required in movement of a quantity of air across the nose and allow storage of this data into a data management program so that standards can be developed and specific patients followed. It is proposed that rhinomanometry be adopted as an objective measurement of nasal function for use in the physical qualification of aviators. Its use in all people involved with aviation during routine flight physicals is also recommended.
