It is defined as a reduction of total lung capacity (TLC) below the 5th percentile of the predicted value, with a preserved one second forced expiratory volume to forced vital capacity ratio ( FEV1 /FVC). Diagnosis therefore requires the use of less commonly available lung volume tests. The ...
Higher Gal-3 concentrations were associated with lower lung volumes (1.4% decrease in percentage of predicted FEV1 per 1 SD increase in log Gal-3; 95% confidence interval [CI], 0.8-2.0%; P < 0.001; 1.2% decrease in percentage of predicted FVC; 95% CI, 0.6-1.8%; P < 0.001...

likely increase the demand for the respiratory system [1-3]. Because static lung loading grows as immersion and breathing gas density increases with depth, the ventilation system is more important in the environment of SCUBA diving than the terrestrial environment [4]. As is well known for all...
Among the 5315 individuals evaluated, 260 (5.1%) had a restrictive spirometric diagnosis (forced vital capacity (FVC) < lower limit of normal (LLN) with forced expiratory volume in the first second to forced vital capacity ratio (FEV1/FVC) LLN; American Thoracic Society (ATS)/European ...
FEV1, forced expiratory volume in 1 s; FK, tacrolimus (FK506); HLA, human leukocyte antigen; ILD/RA, interstitial lung disease/rheumatoid arthritis; IvIG, intravenous immunoglobulins; LB, lymphocytic bronchiolitis; LTx, lung transplantation; M, male; MMF, mycophenolate mofetil; NA, not available;...
Total lung capacity (TLC) measured via plethysmography or nitrogen wash out. It is considered the gold standard for characterizing restrictive thoracic disease. In 2005, the ATS guidelines recommended that the forced expiratory volume in one second (FEV1) be used to grade restrictive deficits on ...
exclusive categories using the forced expiratory volume in 1 s (FEV1), the forced vital capacity (FVC), the FEV1/FVC ratio and the presence of respiratory symptoms: severe obstruction, moderate obstruction, mild obstruction, respiratory symptoms only, restrictive lung disease and no lung disease. ...
Pulmonary function tests to estimate force vital capacity (FVC) and forced expiratory volume in the first second (FEV1) have increasingly been used in patients evaluated for transcatheter aortic valve implantation (TAVI). The impact of obstructive versus restrictive lung disease on mortality remains ...
