Spirometry is the simplest and most widely used pulmonary function test, but other tests may be needed to make a final diagnosis. Lung volume tests are the most accurate measurement of lung capacity .

This pulmonary function test is used to diagnose lung diseases Spirometry, a type of pulmonary function test (PFT), is a non-invasive procedure that can provide information about how well your ...

Then, you take a spirometry test. You do this several times. ... “Normal” results are based on your age, height, and sex. A result that’s not normal may mean you have a lung problem.

Before a spirometry test, most people can continue daily activities as normal, although there are several factors that should be considered. Smokers, for example, should avoid smoking cigarettes ...

Lung disease tests are failing Black patients, studies show. Experts are calling for change. Recent studies cast further concerns about spirometry, the most common lung function test used by ...

Spirometry results will be considered within the normal range if FEV1/FVC > 70% (absolute value) and FVC and FEV1 > 80% of the predicted values. The pattern is classified as obstructive if FEV1 ...

Despite normal spirometry results, some adults with more than 20 pack-years of smoking display respiratory symptoms and experience more exacerbations than asymptomatic smokers, according to ...

Following use of race-neutral vs. -specific lung function equations, spirometry findings and patterns differed, especially among Black children/adolescents, according to results published in JAMA ...

Race-neutral equations for assessing lung function appeared to catch more true-abnormal findings for Black patients than did previously standard race-adjusted spirometry equations, a study showed.

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 ...
