The Vital Capacity in Pulmonary Emphysema
Annals of Internal Medicine, 1964Excerpt It is commonly believed that the vital capacity of patients with obstructive or bullous pulmonary emphysema is more or less diminished; mild emphysema is supposed to be accompanied by sligh...

Fall in vital capacity with posture
British Journal of Diseases of the Chest, 1985In a study of 147 subjects (50 normals, 50 with obstructive, and 47 with restrictive lung function), the mean reduction in forced vital capacity from standing to supine (delta FVC) was 7.5% (SD +/- 5.7), 11.2% (+/- 13.4), and 8.2% (+/- 7.7) respectively, with no significant difference between groups. The respective 95% upper confidence limits were 19%,

It has been recognized that climates with a low relative humidity give relief to some patients with asthma. Inferentially this is due, at least in part, to the beneficial effect of dry air, which will extract more moisture from the bronchial tree than the air of a locality with a higher humidity.

Vital Capacity and Timed Vital Capacity in Normal Men Over Forty
Journal of Applied Physiology, 1956The vital capacity and the 1-second timed vital capacity were measured on 428 healthy men between the ages of 40 and 88 who were living in a rural area of Massachusetts and who came voluntarily for...

Slow vital capacity : differences between expiratory and inspiratory vital capacities
Respiratory function technologists/scient., 2019Introduction: Vital capacity (VC) can be determined through expiratory (EVC) or inspiratory maneuvers (IVC). It is fundamental for determination of lung volumes and its incomplete mobilization has repercussions on the detection of air trapping or pulmonary hyperinflation.

Determinations of vital capacity, heretofore utilized chiefly by physiologists or restricted to the study of serious cardiac or pulmonary disabilities, are now finding a wider application. The ease with which this accurate information is accumulated has greatly facilitated the dissemination of its practical value.

Evaluation of Slow Vital capacity and Forced Vital Capacity in patients with COPD
Clinical Problems, 2018Introduction: According to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria, COPD is diagnosed when the ratio of Forced Expiratory Volume to Forced Vital Capacity (FVC) Methods: the database consisted of a spirometry analysis of 227 healthy individuals and 532 patients with bronchial obstruction during 2013-2017.

Inspiratory and Expiratory Vital Capacity
Chest, 1984Vital capacity (VC) is frequently measured by two different methods (inspiration vs expiration). The difference in results is not readily available in the literature. The VC was measured both ways in 60 subjects, including many with obstructive airway disease. Only a minor difference in mean VC (75 +/- ml SD) was found.

There is no universally accepted means of evaluating the newborn infant with respiratory distress. Various workers have devised different schemes of clinical classification and roentgenological observation of these infants.1-5Laboratory measures of pulmonary function seldom have been applied to the routine evaluation of the distressed newborn infant ...
