In this study, FEV 1 and FVC were significantly low in patients with low or intermediate FEF 25–75% compared to those with normal FEF 25–75% (p<0.001). The ratio FEV 1 /FVC was higher in patients with ...

Background/aim To assess and compare measured ventilatory volumes (forced expiratory volume in 1 s (FEV 1), peak expirium flow (PEF) and maximal voluntary ventilation (MVV)), ventilatory function ...

Yet some manufacturers claim that having to add a quart of oil every 2,000 miles or less is normal while also listing oil-change intervals of 7,500 to 10,000 miles.

The race neutral equations reclassified FEV 1 or FVC from normal to abnormal for 19.2% of Black persons in a large single center cohort study.

FEV1 helps measure the progression of lung conditions such as chronic obstructive pulmonary disease (COPD) or asthma. FEV stands for forced expiratory volume, which is the air you exhale in one ...

Interpreting Results The FEV1/FVC ratio is expressed as a percentage (%). A result is "normal" if the percentage is at or above the predictive value for your age, height, and sex. Percentages below ...

In calculating reference values for FEV 1 and FVC, however, early studies concluded that adjustment for weight was unnecessary because the additional explained variance was small after adjustment for ...

然而，FEV 1 /FVC 比值与全因死亡率之间的关系，尤其是非线性关系，在普通人群中还并不明确。多数研究聚焦于特定人群，特别是 COPD 患者，对于普通人群的探索十分有限。因此，为了填补这一空白，广州医科大学等机构的研究人员开展了一项重要研究，相关成果发表在《BMC Pulmonary Medicine》上。

Similarly, a link between the low peak, rapid decline FEV 1 /FVC trajectory and predominant wheeze (mOR = 9.9; 95% CI, 4.52-21.7) was observed in the CARDIA analysis.
