Objective assessment of nasal resistance in patients with nasal disease
The Journal of Laryngology & Otology, 2003Nasal obstruction is a subjective complaint in patients with nasal disease.The ability to quantitate the nasal ventilation dysfunction would be useful for making the appropriate choice of nasal disease management. This cross-sectional study comprised of 200 adult subjects.

Combined Effects of a Nasal Dilator and Nasal Prongs on Nasal Airflow Resistance
Chest, 2001Nasal prongs (NPs), when used to assess nasal flow, can result in dramatic increases in nasal airflow resistance (NR). The aim of this study was to investigate whether the NP-induced increases in NR could be corrected by the simultaneous use of an internal nasal dilator (ND).NR was estimated by posterior rhinomanometry, in the basal state (NRb), and ...

Alae Nasi Activation (Nasal Flaring) Decreases Nasal Resistance in Preterm Infants
Pediatrics, 1983The effect of alae nasi activation on nasal resistance in a group of healthy preterm infants was measured. Alae nasi activity was determined via the alae nasi electromyogram obtained from skin surface electrodes during both active and quiet sleep. Nasal resistance was calculated from airflow measured with a mask pneumotachograph and transnasal pressure

Nasal airway inspiratory resistance.
The American review of respiratory disease, 1979The relationship between transnasal pressure and nasal flow is markedly curvilinear during tidal breathing in man, and there is poor agreement among the results of various methods used to define this characteristic with a single number. We used Rohrer's equation (P = K1 V + K2 V2), where P = pressure and V = flow, and calculated values for K1 and K2 ...

Computer averaged nasal resistance.
Rhinology, 1989Nasal resistances were measured before and after decongestion of the nasal mucosa by posterior rhinomanometry with a head-out body plethysmograph in 95 adults referred to our nasal airflow laboratory. These resistances were calculated by a time averaging method (1), the equation R = delta P/V at delta P 1.0 cm H2O (2) and R = delta P/V at the point of ...

[Measurement of nasal oscillatory resistance].
Pneumologie (Stuttgart, Germany), 1989The usefulness of a new forced oscillation measuring technique for establishing the airway resistance measured nasally, was investigated in 40 patients. Forced oscillation measurements of airway resistance employing the custo vit and Siregnost FD 5, the interruptor technique and classical rhinomanometry for the measurement of nasal resistance, were ...

Nasal airway resistance and nasal sensation of airflow.
Rhinology. Supplement, 1992Nasal obstruction is a common symptom which is most frequently associated with an increased nasal airway resistance. However it is important to appreciate that the objective measurement of nasal airway resistance does not always correlate with the subjective perception of the degree of nasal obstruction.
