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 ...

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 ...

Home spirometry shows potential for early detection of pulmonary function decline in patients with systemic sclerosis–associated interstitial lung disease (SSc-ILD). It shows good cross ...

It plays a crucial role in your overall respiratory health and fitness. Typically, lung capacity begins to gradually decrease ...

With just chest X-rays, an AI model estimated FVC and FEV1 and had “excellent agreement” when compared with spirometry results, according to results published in The Lancet Digital Health ...

Use of race-neutral vs. race-specific lung function equations led to different interpretations of spirometry findings, ... FEV 1 was between 2.47 L to 2.51 L and FVC was between 3.19 L to 3.36 L ...

Spirometry results in children were different after switching to race-neutral reference equations ... 95% CI 0.349-0.355, P<0.001) and FVC (mean difference 0.350, 95% CI 0.347-0.354, ...

The researchers identified 3,716 (3,474 self- identified white and 242 self-identified Black) individuals with a baseline spirometry evaluation demonstrating an FEV1/FVC ratio <0.7 for inclusion ...

The results of the CAT and your spirometry test will help establish the overall grade and severity. ... A doctor will assess your FEV1/FVC ratio if they suspect you have a lung disorder, ...

They completed a median 3.0 sets of spirometry over a median 2.6 years of follow-up. The study didn't show a similar trajectory for FVC as for FEV 1 among Black patients.
