“…), by means of a portable flow meter such as the Youlten peak flow meter (Clement Clark International), and/or expiration (PNEF), by means of a Wright's mini peak flow meter (Clement Clark International) . PNIF and PNEF are closely correlated , both of them have been demonstrated to be valid for the measurement of nasal flow , and are well tolerated by patients . Although inspiratory manoeuvres may cause alar collapse and thus valve insufficiency, and in few cases, when the nose is totally blocked, it is not possible to obtain a measurement , PNIF has some undoubtable hygienic advantages over PNEF .…”

“…PNIF has been successfully used for the evaluation of treatment in allergic rhinitis and its treatment both in adults and in children/adolescents . Studies have assessed the efficacy of intranasal corticosteroids in patients with NP using PNIF , showing a significant increase in PNIF which was accompanied by subjective improvement of nasal blockage, and by an associated reduction in nasal polyp size .…”

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.

“…This was expected because discrepancies among the clinical, physiologic, and inflammatory asthma control parameters were reported, 32-37 which stressed the importance to manage asthma based on the evaluation of these three key components. 38 In keeping with this, Kirtsreesakul et al 39 observed better correlations between nasal peak flow and mucociliary clearance time, a surrogate marker of underlying mucosal inflammation, than between nasal peak flow and symptom score, which stressed the importance of assessing the multifaceted nature of rhinitis. Because thresholds have not been determined to assign the degree of severity or control with this measurement, we propose that patient's personal best values be determined and control management should aim at maintaining an adequate score accordingly.…”

“…This method includes measurement of peak nasal expiratory flow (PNEF) and peak nasal inspiratory flow (PNIF) . Both PNEF and PNIF have shown good correlations with rhinomanometry and have been demonstrated to be valid for the assessment of an absolute value of nasal airflow . It is likely that the reversibility of both nasal peak flow techniques after decongestion could be used as a simple method for indirectly assessing the degree of underlying mucosal inflammation.…”

Objectives/Hypothesis: Reversibility of nasal airflow after decongestion measured by rhinomanometry is associated with the severity of allergic inflammation. Peak nasal flow is a simpler alternative method for assessing nasal patency. The aim of this study was to evaluate the correlation between changes in peak nasal expiratory and inspiratory flows (PNEFs and PNIFs) after decongestion and nasal mucociliary clearance times (NMCCTs).Study Design: Single-center, prospective cross-sectional study. Methods: One hundred one allergic rhinitis patients were enrolled. Nasal symptoms and NMCCTs were assessed. PNEF and PNIF were performed before and after decongestion. Correlations between changes in PNEF and PNIF after decongestion and NMCCTs were analyzed. One-half the standard deviation of baseline peak nasal flows was used to estimate the minimal clinically important differences (MCIDs) and discriminate between patients with reversible mucosa and with irreversible mucosa.Results: PNEF showed more peak flow improvements after decongestion compared to PNIF. Changes in PNEF had better negative correlations with NMCCTs than PNIF (ρ = −0.49, P < .001 and ρ = −0.34, P < .001, respectively). The MCID values of the PNEF and PNIF were 27.93 and 19.74, respectively. In comparisons of NMCCTs between patients with or without MCID of peak nasal flow after decongestion, PNEF had better discrimination ability compared to PNIF (P = .003 and P = .026, respectively).Conclusions: The limitation of reversibility as measured by peak nasal flows could indirectly point to the affection of mucosal inflammation as indicated by NMCCTs. PNEF is more sensitive to assess peak flow changes after decongestion than PNIF.

Nasal Peak Inspiratory and Expiratory Flow Measurements for Assessing Nasal Obstruction in Allergic Rhinitis

Abstract: Among nasal peak flow measurements, PEFI is the most appropriate objective tool for assessing nasal patency in AR. Peak flows can indicate underlying mucosal inflammation and are more sensitive to assess score changes after treatment than cross-sectional assessment at the initial visit.
