Peak Inspiratory Flows of Adults Exercising at Light, Moderate and Heavy Work Loads
he purpose of this study was to acquire, process, and analyze ventilation and peak inspiratory airflows during exercise to obtain a representative sample set of ventilation data of the general working population. A total of 13 volunteers exercised on a treadmill at three relative work rates of 40%, 60%, and 80% of their maximal aerobic capacity. Ventilation measurements and peak inspiratory air...
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 کاملInspiratory muscle training may increase peak inspiratory flow in chronic obstructive pulmonary disease.
BACKGROUND When choosing a specific inhalation device for a chronic obstructive pulmonary disease (COPD) patient, the internal airflow resistance and the ability of the patient to overcome it and to create an optimal inspiratory flow are essential. OBJECTIVES The purpose of the present study was to investigate: (1) the peak inspiratory flow (PIF) that a patient with COPD can generate while br...
متن کاملEffect of inspiratory muscle strength training on inspiratory motor drive and RREP early peak components.
This study investigated the effect of inspiratory muscle strength training (IMST) on inspiratory motor drive [mouth occlusion pressure at 0.1 s (P(0.1))] and respiratory-related evoked potentials (RREP). It was hypothesized that, if IMST increased inspiratory muscle strength, inspiratory motor drive would decrease. If motor drive were related to the RREP, it was further hypothesized that an IMS...
