Sentence examples for maximum expiratory flow from inspiring English sources

Maximum expiratory flow rate at 30 percent of vital capacity above residual volume served as an index of airway obstruction in comparing the effects of leukotriene C and histamine administered by aerosol to five normal persons.

Expiratory time constant (RCEXP) was measured as the ratio between volume and flow at 75% of maximum expiratory flow and calculated as the product of CSTAT MEAS and RINS.

The most common definitions involve either airflow limitation (American Thoracic Society) or reduced maximum expiratory flow (European Respiratory Society) which is progressive and mostly irreversible.

An increase in maximum expiratory flow and a decrease in expiratory time indicated increased lung recoil in these rats.

The shape of the maximum expiratory flow volume (MEFV) curve has been used to characterize patterns of lung function abnormality.

Confirmatory studies of responsive airways, potentially assessed first by diurnal peak flow, can be done using post-bronchodilator maximum expiratory flow volume curves and methacholine challenges.

In all the studied industries, ventilatory capacity measurements were performed by recording maximum expiratory flow-volume (MEFV) curves on a spirometer, the Pneumoscreen (Jaeger, Wurzburg, Germany).

(MEFV): Maximum expiratory flow-volume; (FVC): Forced vital capacity; (FEV1): One-second forced expiratoryvolume; (FEF50, FEF25): Maximum flow rates at 50% and the last 25% of the vital capacity.

Flow impairment ("obstructive") has conventionally been measured by the forced expiratory volume--1 sec (FEV1); earlier changes, in the small airways are more likely to be detected by the maximal mid-expiratory flow (MMF) and the maximum expiratory flow-volume (MEFV) curve at low lung volumes.

Pulmonary function was assessed by spirometry and maximum expiratory flow-volume curves to determine whether exposure to an occupational environment contaminated with vinyl chloride (VC) fumes and poly vinyl chloride) (PVC) dust is associated with an increased risk of respiratory impairment.

On the first day, each student was asked to perform three maximum forced expiratory flow-volume tests using a flow spirometer (Medgraphics, St . Paul MN, USA), from which the forced vital capacity (FVC) and forced expiratory volume in 1 sec (FEV1) were recorded.
