I. LUNG VOLUMES

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.

Sound transmission in the lung as a function of lung volume

Journal of Applied Physiology, 2002
We were interested in how the transmission of sound through the lung was affected by varying air content in intact humans as a method of monitoring tissue properties noninvasively. To study this, we developed a method of measuring transthoracic sound transit time accurately.

Static Lung Volumes in Singers

Annals of Otology, Rhinology & Laryngology, 1973
It has long been assumed that the superior vocal ability of the trained professional singer arose from a higher than average breathing capacity and consequent above-normal ventilatory efficiency. However, until now, it has not been clear whether this presumed superior pulmonary capacity and breathing efficiency arose from training, from heredity, or ...

Ventilation strategy using low tidal volumes, recruitment maneuvers, and high positive end-expiratory pressure for acute lung injury and acute respiratory distress syndrome: a randomized controlled trial.

Journal of the American Medical Association (JAMA), 2008
CONTEXT Low-tidal-volume ventilation reduces mortality in critically ill patients with acute lung injury and acute respiratory distress syndrome. Instituting additional strategies to open collapsed lung tissue may further reduce mortality. OBJECTIVE To

Lung volumes in exacerbations of asthma

The American Journal of Medicine, 1966
Abstract Lung volumes and forced expiratory volume in one second (FEV 1 ) were measured serially in thirty patients during recovery from episodes of severe asthma. Abnormalities of lung volumes were present in all patients at some stage during the course of the illness.

Lung deformations at minimal volume

Journal of Applied Physiology, 1980
Minimal volume (MV, gas plus tissue volume at zero transpulmonary pressure) was determined in excised dog lobes after inflation with air and with saline. MV was significantly greater in saline-filled lobes than air-filled lobes. Air inflation was performed with the lobe supported in two different ways, which were chosen to produce different ...

The effects of body mass index on lung volumes.

Chest, 2006
BACKGROUND Obesity is a major health issue in North America, and the trend is for obesity to be a more important medical issue in the future. Since obesity can cause respiratory symptoms, many obese people are referred for pulmonary function tests (PFTs).

Lung volumes: measurement, clinical use, and coding.

Chest, 2012
Measurement of lung volumes is an integral part of complete pulmonary function testing. Some lung volumes can be measured during spirometry; however, measurement of the residual volume (RV), functional residual capacity (FRC), and total lung capacity ...

Lung Volume Reduction

2011
Lung volume reduction surgery (LVRS) is a viable option for a select group of emphysema patients. Effective preoperative pulmonary rehabilitation and careful patient selection criteria promote favorable outcomes. Effective perioperative pain management and early extubation are significant factors that minimize postoperative complications and lead to ...

Lung Volumes in Polynesian Children

American Review of Respiratory Disease, 1987
Polynesian (Maori and Pacific Island) children account for approximately one quarter of the children in New Zealand, but good data for lung function in this group are not available. In this review, we report lung volume measurements in 571 healthy children 5 to 13 yr of age: 270 Polynesians (139 boys and 131 girls) and 301 Europeans (177 boys and 124 ...
