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。
Around 20% to 25% of individuals with rapidly declining FEV1/FVC trajectories experienced wheezing and usual phlegm/bronchitis as adolescents/young adults, according to results published in The ...
In an effort to see if a deep learning-based AI model could estimate FVC and FEV 1 from chest X-rays, Ueda and colleagues trained, validated and internally tested the model using 134,307 X-ray and ...
For white patients, 15.0% had either their FEV 1 or FVC recategorized from abnormal under the race-adjusted equations to normal using the race-neutral equation. Their FEV 1 decline was similar to ...
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.
There is significant disparity in the ratios for postbronchodilator FEV1/FEV6 and FEV1/FVC %, and this disparity is very pronounced in women.
Summer 2025 forecast calls for 'overwhelmingly above normal' heat starting in June The summer forecast calls for hotter-than-normal temperatures from coast-to-coast, according to NOAA's Climate ...
Defined by reductions in FEV 1 and FVC and a normal TLC, the nonspecific pattern has classically been considered a marker of early airway disease. The idea is that early, ...
FEV 1 is the maximum amount of air a person can forcibly exhale in one second and FVC is the forced vital capacity - maximum amount exhaled forcefully after breathing in deeply.
