Respiratory muscle performance with stretch-shortening cycle manoeuvres: maximal inspiratory pressure-flow curves

open access: yes, 2005
Aim: To test the hypothesis that the maximal inspiratory muscle (IM) performance, as assessed by the maximal IM pressure-flow relationship, is enhanced with the stretch-shortening cycle (SSC).

Intrasubject variability of maximal expiratory flow volume curve. [PDF]

open access: yesThorax, 1977
Analysis of airflow in the terminal portion of the maximal expiratory flow volume curve has been suggested as a useful test for the early diagnosis of chronic airways obstruction. Whether such an analysis can identify early disease, and whether any subsequent action can prevent the progress of chronic airways obstruction, is unknown and will require ...

Quantifying the shape of maximal expiratory flow-volume curves in healthy humans and asthmatic patients [PDF]

open access: yesRespiratory Physiology and Neurobiology, 2016
Differences in the absolute flow and volume of maximal expiratory flow-volume (MEFV) curves have been studied extensively in health and disease. However, the shapes of MEFV curves have received less attention. We questioned if the MEFV curve shape was associated with (i) expiratory flow limitation (EFL) in health and (ii) changes in bronchial caliber ...

Validity of simple physical models in interpreting maximal expiratory flow-volume curves

Respiration Physiology, 1972
Abstract The effort independent portion of the maximal expiratory flow-volume (MEV) curve can be described by means of simple equations representing one-compartment physical models, based on Mead's equal pressure point (EPP) concept. Three such descriptions have been tested on flow-volume curves obtained in 17 healthy individuals during forced ...

Quantifying the shape of the maximal expiratory flow–volume curve in mild COPD

Respiratory Physiology and Neurobiology, 2015
Maximal expiratory flow-volume (MEFV) curve evaluation using absolute and percent predicted values of flow and volume are used to diagnose respiratory disease, but the shape of the curve is rarely used. Three mathematical methods were used to quantify shape of MEFV curves in subjects with mild COPD (n=19) and matched healthy controls (n=15). Those with

The Maximal Expiratory Flow-Volume Curve in Normal Subjects in India

Chest, 1986
Data on pulmonary function, with particular reference to flow-volumes, were obtained in 760 normal healthy Indians in Bombay, who had never smoked and who had no symptom or history of cardiorespiratory disease. Prediction equations were derived for spirometric parameters and for maximal expiratory flows. The maximal expiratory flow-volume curves showed
