There are several tests that doctors can use to diagnose and monitor COPD. Let's take a look at what abnormal values for ...

Miller 1996 [1]) shows a normal spirogram showing the measurements of forced vital capacity (FVC), forced expired volume in one second (FEV1) and forced expiratory flow over the middle half of the FVC ...

attaches a measure of precision to the data on which decision making is based. ATS, American Thoracic Society COPD, chronic obstructive pulmonary disease FEV1, forced expiratory volume in one second ...

The researchers identified 3,716 (3,474 self- identified white and 242 self-identified Black) individuals with a baseline ...

Lung function was assessed by measuring forced expiratory volume (FEV1), forced vital capacity (FVC), and the ratio of these two values (FEV1/FVC). Regression model was performed to determine the ...

Methods We studied repeated measurements of FEF25–75% and FEV1/FVC on 158 traffic enforcers from the Metropolitan Manila Development Authority (MMDA) Health Study using mixed-effects models with ...

The researchers noted the mean (SD) smoking pack-years was 40.32 (35.18); mean FEV1, 2.22L (58.50%); mean FVC, 3.94L (75.44 ... lack of measurement of sputum volume and consistency, and the use ...

32.4% had ongoing silica exposure after receiving a silicosis diagnosis. Further silica exposure after silicosis diagnosis was not predictive of FEV1, FVC or TLco (p>0.05) decline. Percent predicted ...

Demographic data, time between fracture and pulmonary function tests (PFT), spirometric parameters in litres and % of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), ...

Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio were compared with local and international reference ranges3,4. Asthma symptoms were recorded using the ...

Methods This 26 week, multicentre, double-blind, parallel-group, placebo and active controlled (open-label tiotropium) study randomised male or female patients ≥40 years of age with moderate-to-severe ...

N-acetylcysteine (NAC) nebulizer therapy is effective and safe in the short-term (12 weeks) for reducing phlegm in COPD.
