Effect of compression pressure on forced expiratory flow in infants

open access: yes, 1986
The effect of the force of compression on expiratory flow was evaluated in 19 infants (2-13 mo of age) with respiratory illnesses of varying severity. An inflatable cuff was used to compress the chest and abdomen.

Classification of Maximal Expiratory Flow-Volume Types Observed in Non-Smoking Healthy Young Subjects [PDF]

open access: yes, 1990
Pulmonary function tests were performed on 234 healthy non-smoking young subjects (189 males and 45 females free from respiratory and allergic symptoms).

Prediction of maximal expiratory flow in excised human lungs

open access: yes, 1980
The predictions of the wave-speed theory of flow limitations were tested against measured values of maximal expiratory flow (Vmax) in nine normal excised human lungs.

A method for digitized flow-volume curves and expiratory resistance measurements using standard ventilatory equipment [PDF]

open access: yes, 1992
Pulmonary resistance may be assessed in ventilated patients by analysis of passive expiratory pressure and flow properties of the respiratory system. Such measurements are generally complex and require specialized equipment.

Dependence of maximal flow-volume curves on time course of preceding inspiration

open access: yes, 1993
Thirteen normal subjects, sitting in a body plethysmograph and breathing through a pneumotachograph, performed forced vital capacity maneuvers after a rapid inspiration without or with an end-inspiratory pause (maneuvers 1 and 2) and after a slow ...

Expiratory flow limitation and regulation of end-expiratory lung volume during exercise

open access: yes, 1993
To investigate the impact of expiratory flow limitation (FL) on breathing pattern and end-expiratory lung volume (EELV), we imposed a small expiratory threshold load for a few breaths during exercise in nine volunteers (29–62 yr): six were healthy and ...

Effect of lung volume on forced expiratory flows during rapid thoracoabdominal compression in infants

open access: yes, 1995
The rapid thoracoabdominal compression (RTC) technique is commonly used in pulmonary function laboratories to assess flow-volume relationships in infants unable to produce a voluntary forced expiration maneuver. This technique produces forced expiratory

Effects of thoracic gas compression on maximal and partial flow-volume maneuvers

open access: yes, 1989
Airway hysteresis can be evaluated by comparing maximal (MEFV) and partial (PEFV) expiratory flow-volume curves. The maneuvers are often obtained from pulmonary function systems that are subject to gas-compression artifacts.

Pattern and mechanism of airway response to hypocapnia in normal subjects

open access: yes, 1979
We examined the bronchoconstriction produced by airway hypocapnia in normal subjects. Maximal expiratory flow at 25% vital capacity on partial expiratory flow-volume (PEFV) curves fell during hypocapnia both on air and on an 80% helium- 20% oxygen ...
