The American review of respiratory disease, 1984
Effects of recumbency on nasal patency were determined in adult subjects by a sensitive computer-assisted posterior rhinometric technique. A modified body plethysmograph was employed to measure air flow and to avoid the disadvantages of facial masking and nasal intubation.

Measurement of nasal patency using a Vitalograph
Clinical & Experimental Allergy, 1978SummaryA standard Vitalograph was used to measure the volume or air inspired through the mouth (M‐FIV0.5) and nose (N‐FIV0.5) in 0.5 sec. The ratio or these parameters was used as a nasal patency index (NPI) and the characteristics of NPI and N‐FIV0.5 investigated in terms of reproducibility and sensitivity.

Impact of Menthol Inhalation on Nasal Mucosal Temperature and Nasal Patency
American Journal of Rhinology, 2008Background Menthol is a natural herbal compound. Its isomer L-menthol presents the characteristic peppermint scent and is also responsible for the cooling sensation when applied to nasal mucosal surfaces because of stimulation of trigeminal cold receptors.

Nasal Patency and Its Assessment
American Journal of Rhinology, 1987The propagation of nasal airflow resistance and its indispensable role in the modification of inspiratory air is described. Aerodynamic features and principles of rhinomanometric techniques which are commonly involved in the assessment of nasal patency are outlined.

American Journal of Rhinology, 1988
Clinical investigations over the last decade have revealed that sleep may not be the benign rejuvenating state it was once considered. Sleep apnea is now frequently recognized, and it is clear that patency of the nasal passages and the nasopharynx is crucial for successful treatment of the syndrome.

The Influence of Nasal Patency on Accelerometric Transduction of Nasal Bone Vibration
The Cleft Palate-Craniofacial Journal, 1990The transmission characteristics of nasal tract energy to a nasal accelerometer were evaluated in relation to nasal tract airway resistance. Ten adult speakers repeated three utterances while recordings of nasal bone vibration, as detected by miniature accelerometers, were obtained simultaneously from both sides of the nose and referenced to a common ...

Rhinometry: measurement of nasal patency.
Annals of allergy, 1982Airflow through the nose is a complex function since the nose is a tortuous series of channels. Mathematicians can only guess at formulas which would explain the intricacies of the nasal passages and flow of air through them. For practical purposes a "black box technique" may be used in which input and output are measured at either end of the black box
