“…Nasal obstruction is difficult to quantify directly by clinical examination, so objective assessments such as PNIF, rhinomanometry and acoustic rhinometry are used (120)(121)(122). In daily practice, PNIF is attracting more and more attention, because it is simple, cheap, fast and readily available (122,1411). Moreover, PNIF is reproducible and related to the signs of rhinitis, as determined by clinical examination (122).…”

“…Further, nasal patency assessment with objective measures, such as Peak Nasal Inspiratory Flow (PNIF), has been evaluated in a large number of studies on healthy individuals (11)(12)(13) , patients complaining of nasal obstruction (14) , medical treatment of the nose (15) , nasal surgery procedures (16,17) and repeatability (18) .…”

Background: The effect of pulmonary pathology on peak nasal inspiratory flow (PNIF) remains largely unknown. We investigated an association between a diagnosis of asthma and of lung function on PNIF when adjusted for possible confounders. Further, we investigated the perception of nasal obstruction in asthmatics compared to healthy controls when adjusted for PNIF.Methodology: Eighty-seven asthmatics and 92 non-asthmatic controls underwent PNIF (categorized into groups of high, medium and low), acoustic rhinometry (AR) and spirometry, and we assessed symptoms of nasal obstruction on visual analogue scales (VAS) in three categories.Results: PNIF was significantly associated with asthma and forced expiratory volume in the first second (FEV1) (% predicted).Other factors associated with PNIF were the degree of nasal obstruction measured both subjectively on a VAS and objectively with AR, age and disease status. Asthma patients were 19 times more likely to be in a higher VAS category compared to non-asthmatic controls independent of PNIF group. Conclusion:Special care has to be taken when interpreting PNIF values in patients with asthma or reduced FEV1 (% predicted).The sensation of nasal obstruction in asthmatics is different from controls despite being in the same PNIF group.

“…PNIF has been widely used in studies aimed at the assessment of nasal airflow, especially in allergic rhinitis patients. The studies found in the literature address data on sensibility, diagnosis accuracy, reproducibility, and reference values of the instrument (8)(9)(10)(11)16,17,21,22) . Our sample showed higher prevalence of mouth-breathing patients in the age group of 6-10 years (Table 1), in agreement with findings of the literature (23,24) -even though some studies have not identified differences concerning age (7,19) .…”

“…Patients were briefly oriented about how to use the instrument; they were supposed to stand up, put on the face mask, covering the regions of the mouth and nose, breathe out and then breathe in at their utmost. We performed three measures and considered the highest value for the analysis (9)(10)(11)(12)16,17) . Data were analyzed using the SPSS statistical program, with significance level set at 5%.…”

OBJETIVO: Comparar o uso do espelho de Glatzel e do peak nasal inspiratory flow na avaliação de indivíduos respiradores orais, bem como analisar a correlação dos dois instrumentos. MÉTODOS: Foram avaliadas 64 crianças, sendo 32 respiradoras orais e 32 respiradoras nasais, na faixa etária de 4 a 12 anos. Os respiradores orais, diagnosticados de acordo com equipe multiprofissional, foram subdivididos de acordo com a causa da obstrução. Foram utilizados o espelho de Glatzel e o peak nasal inspiratory flow nos dois grupos para avaliação da permeabilidade e fluxo aéreo nasal. Os dados foram submetidos à análise estatística. RESULTADOS: O espelho de Glatzel diferenciou o modo respiratório considerando-se os estratos gênero, faixa etária, peso, altura e índice de massa corporal da amostra. Entretanto, não foi capaz de dar indícios sobre a causa da respiração oral. Com o uso do peak nasal inspiratory flow, não foi possível diferenciar o modo respiratório e tampouco a causa da respiração oral. Na amostra pesquisada, não houve correlação entre os instrumentos utilizados. CONCLUSÃO: O espelho de Glatzel mostrou ser capaz de identificar indivíduos com e sem obstrução nasal, embora não tenha sido possível diferenciar os subgrupos de respiradores orais entre si com o uso do instrumento. Já o peak nasal inspiratory flow mostrou-se capaz de diferenciar apenas respiradores nasais de respiradores orais cirúrgicos. Foi encontrada baixa correlação entre os dois instrumentos.
