Effects of lung volume, volume history, and methacholine on lung tissue viscance
Journal of Applied Physiology, 1989We examined the effects of lung volume change and volume history on lung resistance (RL) and its components before and during induced constriction. Eleven subjects, including three current and four former asthmatics, were studied. RL, airway resistance (Raw), and, by subtraction, tissue viscance (Vtis) were measured at different lung volumes before ...

The respiratory system is an elastic structure changing volume when pressures are generated by inspiratory or expiratory muscles. If the muscles are relaxed the respiratory system returns to its relaxation volume (Vr) (referred to in the pediatric literature as the elastic equilibrium volume [EEV]), which in normal subjects is the end-expired volume or

Lung Transplantation and Lung Volume Reduction Surgery
Comprehensive Physiology, 2011AbstractSince the publication of the last edition of the Handbook of Physiology, lung transplantation has become widely available, via specialized centers, for a variety of end‐stage lung diseases. Lung volume reduction surgery, a procedure for emphysema first conceptualized in the 1950s, electrified the pulmonary medicine community when it was ...

Bronchoscopic lung volume reduction
Multimedia Manual of Cardio-Thoracic Surgery, 2007Emphysema is a debilitating lung disease continuing to be a major source of morbidity and mortality in the developed countries. Medical treatment is the mainstay of therapy and consists of smoking cessation, pulmonary rehabilitation, administration of bronchodilators and, when indicated, steroids and supplemental oxygen.

Measurements of lung volume play an integral role in the laboratory evaluation of patients with known or suspected lung disease. Several techniques are available to measure absolute lung volumes (containing residual volume). It should be noted that these techniques measure different theoretical volumes and may produce different results in patients with

Lung volume, closing volume, and gas exchange
Journal of Applied Physiology, 1982The effect of a voluntary reduction in lung volume on arterial O2 saturation (SaO2) was studied in 10 normal subjects aged 19–63 yr. SaO2 was measured by ear oximetry first during tidal breathing at functional residual capacity, and then during tidal breathing at 380 ml above residual volume.

Static lung volumes are commonly described as volumes or capacities. Volumes are not subdivided and include tidal volume (Vt), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and residual volume (RV). However, capacities consist of at least two lung volumes and include total lung capacity (TLC), vital capacity (VC), functional ...

Bronchoscopic Lung Volume Reduction
Clinics in Chest Medicine, 2013The management of obstructive lung disease, particularly emphysematous lung disease, is aggressively being pursued. The patient populations that will experience the greatest benefit with lung volume reduction are those that are the worst candidates for surgical intervention.

Pediatrics, 1965
A three-year longitudinal study of a variety of lung function tests in 147 normal children has been carried out to permit better separation of growth effects (by covariance analysis) from individual variation, to supply information not previously available, and to permit study of the interrelationships of the tests in normal subjects. In
