Peak nasal inspiratory flow evaluation as an objective method of measuring nasal airflow.
UNLABELLED Acoustic rhinometry, rhinomanometry and Inspiratory Peak Nasal Flow (IPNF) are used in order to objectively assess nasal patency. These are expensive not very practical tests, except for IPNF, which is a fast, simple and low cost method. OBJECTIVE To assess IPNF in healthy individuals complaining of nose obstruction caused by allergic rhinitis. METHOD IPNF use in 78 individuals w...
متن کاملNasal peak inspiratory flow at altitudeFor
Nasal peak inspiratory flow at altitude. P.W. Barry, N.P. Mason, J-P. Richalet. #ERS Journals Ltd 2002. ABSTRACT: The present study investigated whether there are changes in nasal peak inspiratory flow (NPIF) during hypobaric hypoxia under controlled environmental conditions. During operation Everest III (COMEX 997), eight subjects ascended to a simulated altitude of 8,848 m in a hypobaric cham...
متن کاملThe clinical value of peak nasal inspiratory flow, peak oral inspiratory flow, and the nasal patency index.
OBJECTIVES/HYPOTHESIS The aim of this study was to ascertain the most reliable objective measurement for the assessment of nasal patency by investigating the relationship between peak nasal inspiratory flow, peak oral inspiratory flow, and the nasal patency index in relation to the patient's subjective perception regarding nasal obstruction. STUDY DESIGN Prospective cohort study. METHODS Th...
متن کاملPeak nasal inspiratory flow as outcome for provocation studies in allergen exposure chambers: a GA2LEN study
BACKGROUND The GA2LEN chamber has been developed as a novel mobile allergen exposure chamber (AEC) allowing standardized multicenter trials in allergy. Hitherto, subjective nasal symptom scores have been the most often used outcome parameter, but in standardized modern trials objective parameters are preferred. Despite its practicability, the objective parameter peak nasal inspiratory flow (PNI...
متن کاملMeasuring oral and nasal airflow in production of Chinese plosive
This study reports a new integrated device for measuring oral and nasal airflow with lossless speech recording with preliminary results on Chinese plosives. An acoustically transparent fiber-made mask acts both as a material for airflow resistance and a support for partitioning oral and nasal chambers. Two pressure sensors placed directly on the mask measure air pressure signals that correspond...
