Nasal 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...

The 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...

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...

Peak Expiratory Flow Rate in Healthy Children from Tehran

Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines.  Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
