13 Ιουν 2019 · Introduction. Worldwide, spirometry is the most frequently used pulmonary function test. The forced expiratory volume in the first second. (FEV 1), the forced vital capacity (FVC) and the...
Normal FEV1 and FVC 80-120% predicted. FEV1/VC increased: suggests restriction. FEV1/VC < LLN (ATS) or < 70% (GOLD): airflow. Either forced (FVC) or slow (SVC) vital capacity can be used to determine FEV1/VC ratio obstruction present. - Severity* Mild Moderate Severe.

14 Οκτ 2019 · It has been estimated that a 10% decline in FEV 1 or FVC corresponds to a 28% increase in cardiovascular mortality. A 3-tiered FVC stratification (<85%, 85%–95%, >95% predicted) was associated with progressive changes in mortality risk in nonsmoking adults from the Third National Health and Nutrition Examination Survey (NHANES-III), beyond ...
6 Νοε 2020 · BMI: body mass index; FEV 1: forced expiratory volume in one second; FVC: forced vital capacity; FEF x: forced expiratory flow at 25%, 50%, 75% and 25-75% of FVC, IQR: interquartile range.
1. cardiovascular mortality. A 3-tiered FVC stratification (<85%, 85%–95%, >95% predicted) was associated with progressive changes in mortality risk in nonsmoking adults from the Third National Health and Nutrition Examination Survey (NHANES-III), beyond that explained by Framingham risk scores.
ABSTRACT: Forced vital capacity (FVC) measures lung function and predicts coronary heart disease (CHD); whether it provides additive prediction over CHD risk factors has not been established. We examined whether FVC adds to the prediction of all-cause mortality provided by Framingham Risk Score (FRS) alone.
