The aims of this paper are to provide reference equations for static lung volumes for a cohort of healthy never-smoking white European adults between 65 and 85 years of age and to compare the predicted values of this sample with those from other studies including middle-aged adults.

22 Μαρ 2024 · These tests measure how much air a person can force out of their lungs within 1 second and in total. The results of a spirometry test can help diagnose obstructive lung disease and other ...
Average values in healthy patients aged 20-60 range from 5.5 to 4.75 liters in males and from 3.75 to 3.25 liters in females. FEV1, Forced Expiratory Volume in 1 Second; This parameter measures the amount, or volume, exhaled by a patient in the first second of the expiration after a full inspiration. Average values in healthy patients aged 20 ...

Normal Lung Volumes. ERV = expiratory reserve volume; FRC = functional residual capacity; IC = inspiratory capacity; IRV = inspiratory reserve volume; RV = residual volume; TLC = total lung capacity; VC = vital capacity; VT= tidal volume. FRC = RV + ERV; IC = VT + IRV; VC = VT+ IRV + ERV. In these topics. Airflow, Lung Volumes, and Flow-Volume ...
1 Δεκ 2009 · Measurements and main results: Plethysmography provided higher values than the dilutional method for all lung volumes, with wide limits of agreement. In addition to height, our reference equations confirm the age- and body size dependence of lung volumes in older subjects.
Forced Expiratory Volume in the first second (FEV1): The volume delivered in the first second of a FVC maneuver. Obstruction is defined as FEV1/FVC ratio below the lower limits of normal. The rule of thumb is if FEV1/FVC is down 10 or more from the predicted value.
