FEV1/FVC ratio explained We can use FEV1 and FVC to describe different properties ofspirometry, the most available and useful pulmonary function test. Spirometry may be performed when the doctor suspects any kind of airflowobstruction, e.g., asthma or chronic obstructive pulmonary disease (COPD)....

Genome-wide association study on the FEV1/FVC ratio in never-smokers identifies HHIP and FAM13A 慢性阻塞性肺病(COPD)是全世界第三大死亡原因。吸烟被认为是工业化国家COPD的最重要的危险因素,大多数关于易感基因的研究都集中在...
在此,关键性气流受限的两个肺功能指标是FEV 1及FVC。FEV 1可同时作为呼气的流量(L/s)和容量指标(L),因而其下降既可反映气道阻塞等引起的呼气流量下降,也可反映受肺容积扩张受限的影响。为了对此进行鉴别,引入了FVC进行矫正,即FEV 1/FVC的比值,比值下降说明FEV 1的降低主要由于气道阻塞引起,否则是由于肺容积...

To determine the agreement between the FEV1/FEV6 ratio and the FEV1/FVC ratio in an elderly population. The study sample consisted of 3874 participants in a cross-sectional population survey in Tromso¨, Norway, aged 60 years or more, in whom acceptable
In addition, the LLN of the FEV1/FVC ratio was calculated for the Hankinson and Crapo reference values. The number of studies interpreted as obstructed varied from 37% using the Hankinson data set to 55% using the 75% fixed ratio method. Comparing the LLN method vs the 70% fixed ratio ...
The present study was undertaken to find out the FEV1 % and the ratio of FEV1/FVC % in chronic obstructive pulmonary disease conditions. Materials and Methods: The present study was conducted at Kasturba Medical College, Mangalore, after the institutional ethical clearance and informed consent from...
ABS46: Lung function testing in the elderly — can we still use FEV1/FVC <70% as a criterion of COPD? Chronic obstructive pulmonary disease (COPD) can be diagnosed when the FEV1/FVC ratio is below 70%, according to Global initiative for chronic obstructive ... Astri Medb,H Melbye - 《...
