Objective measures can be used to assist the clinician to diagnose and treat nasal obstruction and also to quantify nasal obstruction in research. Objective measurements of nasal obstruction are as important as objective measurements of lung function. peak nasal inspiratory flow (PNIF), acoustic rhinometry (AR) and rhinomanometry (RM), with their specific peculiarity, assess different aspects of nasal obstruction. From the studies available in the literature, it seems that these methods roughly correlate with each other and that all of them can be alternatively utilized very well in research as well as in clinical practice. This review describes the various methods that can be used to measure nasal patency, airflow and resistance, mainly peak nasal inspiratory flow, rhinomanometry and acoustic rhinometry. PNIF has been demonstrated to be reproducible and as good an indication of objective nasal patency as formal rhinomanometry and has the advantage to be cheap, simple and suitable for serial measurements and for home use even in the paediatric population. PNIF normative data are available for children, adults and elderly subjects, and the availability of unilateral PNIF normal values allows evaluation of nasal sides separately. Just as in the lower airways, objective and subjective evaluation gives different information that together optimizes the diagnosis and the treatment of our patients. We argue that PNIF should be used regularly in every outpatient clinic that treats patients with nasal obstruction.

“…PNIF, in fact, has been used for the evaluation of the treatment in allergic rhinitis patients (4) , to study nasal valve collapse (5,6) and for the evaluation of septoturbinoplasty outcome (7) . In the recent past, normal PNIF values both for adult and paediatric populations have been published by many authors (2,(8)(9)(10)(11)(12)(13) , also unilaterally (14) , allowing the application of this technique to the results of septoplasty (15) . In studying PNIF values, some authors applied PNIF to sitting volunteers (2,8,10,11,13,16) , whilst others to standing volunteers (9,12) .…”

“…PNIF has been deemed a simple and quick alternative, which can be easily learned and interpreted (9,10) . It is a well studied technique, and it bears basal parameters of normality specified for adults of different ethnical backgrounds (11)(12)(13) and also for the pediatric population (14)(15)(16)17) .…”

Background: Peak nasal inspiratory flow (PNIF) has been proposed as a simple method to evaluate nasal patency. Asthma and allergic rhinitis are commonly associated, and lower airway assessment can provide information concerning an objective interpretation of nasal function. Aims: To determine whether the PNIF is correlated with peak expiratory flow (PEF) in children and adolescents. Methods and Results: Cross-sectional study carried out in healthy students randomly chosen in 14 public schools of the city of Belo Horizonte. PNIF and PEF were assessed for each subject as the following characteristics: gender, height, weight and age. We created a linear regression model to explain the PNIF, in which we included all the variables with a p value ≤ 0.25 in a univariate analysis, and to calculate the relationship between the maximum PNIF and maximum PEF by the Spearman correlation coefficient. In total, 297 healthy subjects, aged between six and eighteen years were evaluated. A positive and significant correlation between PNIF and PEF was found. Conclusions: PEF is predictive of PNIF. However, these measures evaluate two distinct segments of the airways and should be both obtained for a more precise assessment of airflow limitation.

North African reference equation for peak nasal inspiratory flow

Abstract: This is the first published study to calculate a reference equation for peak nasal inspiratory flow in North African subjects. This equation enables objective evaluation of nasal airway patency in patients of North African origin.
