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...

Epidemiologic research has revealed a substantial portion of the general population with abnormal spirometry results that are characterized by decreased FEV1 and FVC but a preserved FEV1/FVC ratio. This restrictive spirometry pattern (RSP) is inconsistently defined in the literature and not well addressed by current guidelines; there is an accumulating

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.

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.

Timed vital capacity in bronchial asthma [PDF]
Journal of Allergy, 1953 Abstract 1.1. Eighty-two timed vital capacity measurements were studied in 36 patients with chronic bronchial asthma during (a) the symptom-free stage, (b) "spontaneous attacks," and (c) experimentally induced attacks of "asthma." 2.2. Symptom-free patients had a first second to total vital capacity ratio of 57.5 per cent.

THE VITAL CAPACITY OF THE NEGRO CHILD
JAMA: The Journal of the American Medical Association, 1927The purpose of this study is to ascertain the vital capacity of a group of normal negro children and compare these vital capacities with those of a group of white children living in the same territory. The negro child forms an integral part of our population and must be considered in any health program. It has been shown that negro children are heavier

This study of the vital capacity of negroes is a by-product of a hookworm study in a group of about 2,000 white and negro children of school age, in south Alabama. These children were measured carefully to determine the effect of varying intensities of hookworm infection on normal growth and development.

The timing of the forced vital capacity.
The American review of respiratory disease, 1979Based on analysis of more than 2,500 forced vital capacity (FVC) maneuvers, we examined 2 aspects of the standards for spirometry recommended by the 1977 Snowbird Workshop concerning the timing of the FVC maneuver. We compared the forced expiratory volume in one sec (FEV1) when timing was initiated by the back extrapolation method with FEV1 when timing
