Texture-Based Automated Quantitative Assessment of Regional Patterns on Initial CT in Patients With Idiopathic Pulmonary Fibrosis: Relationship to Decline in Forced Vital Capacity.

AJR. American journal of roentgenology, 2016
OBJECTIVE The aim of our study was to retrospectively determine predictive factors for a decline in forced vital capacity (FVC) on initial CT using texture-based automated quantification in patients with idiopathic pulmonary fibrosis (IPF).

Slow vital capacity : differences between expiratory and inspiratory vital capacities

Respiratory function technologists/scient., 2019
Introduction: 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.

Forced vital capacity in idiopathic pulmonary fibrosis--FDA review of pirfenidone and nintedanib.

New England Journal of Medicine, 2015
In 2014, the FDA approved two drugs for idiopathic pulmonary fibrosis that posed a regulatory challenge: the primary efficacy variable studied was the change in forced vital capacity, which hadn't been established as a surrogate for clinically meaningful

Evaluation of Slow Vital capacity and Forced Vital Capacity in patients with COPD

Clinical Problems, 2018
Introduction: 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.

Long-Term Effects of Lung Volume Recruitment on Maximal Inspiratory Capacity and Vital Capacity in Duchenne Muscular Dystrophy.

Annals of the American Thoracic Society, 2016
RATIONALE Lung volume recruitment therapy slows rate of decline of lung function in neuromuscular disease, possibly due to enhanced airway clearance, reduced atelectasis, or prevention of chest wall contractures.

VITAL CAPACITY OF NEGRO RACE

JAMA: The Journal of the American Medical Association, 1926
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.

Normal values for the ratio of one-second forced expiratory volume to forced vital capacity.

American Review of Respiratory Disease, 2015
Normal standards for the ratio of 1-second forced expiratory volume to forced vital capacity have previously either assumed a value greater than 70 or 75 per cent or else provided prediction formulas based on populations of small size or groups that ...
