Forced expiratory volume in 1 second (FEV1) measures how much air you can forcefully exhale in one second. A low FEV1 suggests a breathing obstruction caused by conditions like chronic obstructive ...

Extracting lung function measurements from electronic health record (EHR) data through an automated tool, such as Microsoft SQL Server’s full-text search feature, may be efficient and improve the ...

Spirometry is a standard test doctors use to determine how well your lungs function. A score that measures airflow into and out of your lungs can help diagnose COPD and determine the best treatments.

The guideline-recommended FEV1:FVC value of less than 0.70 is the optimal cutoff for the diagnosis of clinically significant chronic obstructive pulmonary disease (COPD), researchers say. The study, ...

Abstract: Preserved ratio impaired spirometry (PRISm) is a pulmonary function pattern characterized by a forced expiratory volume in one second (FEV1) to forced vital capacity ratio greater than 0.70, ...

A spirometry is a pulmonary function test that measures how much air a person breathes out, and how quickly. Pulmonary function tests measure how well the lungs are working. It is an office-based ...

COPD Severity and Life Expectancy Doctors use a classification system called the Global Initiative on Obstructive Lung Disease (or GOLD) system to determine how severe your COPD is. It's based on how ...

A large observational study of former and current smokers found that higher blood omega-3 fatty acids were associated with ...

The results of spirometry test can be interpreted to provide valuable information about the function of the lungs and respiratory system and guide diagnostic and treatment decisions. There are various ...

Better lung function, expressed as higher forced vital capacity (FVC), is associated with a reduced risk for the onset of heart disease, diabetes, and stroke over a follow-up period of approximately ...
