16 Ιουλ 2023 · This article looks at lung volumes and capacities, their measurements and effects of common pathology. This division allows for assessment of the mechanical condition of the lungs, its musculature, airway resistance and the effectiveness of gas exchange at the alveolar membrane.
Our reference equations may be used for the prediction of lung volumes in white patients 65 to 85 years of age with standing heights for women between 144 and 174 cm and men between 152 and 181 cm. The use of our reference equations beyond these age and height limits may lead to inaccuracies.
lung volumes measured by helium dilution as compared with plethysmography. 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
Lung volumes measurement is an integral part of pulmonary function test. These volumes tend to vary, depending on the depth of respiration, ethnicity, gender, age, body composition and in certain respiratory diseases. A number of the lung volumes can be measured by Spirometry- Tidal volume, Inspiratory reserve volume, and Expiratory reserve volume.
The four lung capacities are calculated as follows: Vital capacity (VC) = Inspiratory reserve volume (IRV) + Tidal volume (TV) + Expiratory reserve volume (ERV) Inspiratory capacity (IC) = Inspiratory reserve volume (IRV) + Tidal volume (TV) Functional residual capacity (FRC) = Expiratory reserve volume (ERV) + Residual volume (RV)
4 Απρ 2024 · GLI lung volume reference equations demonstrated a poor fit for our cohort, especially in females. Therefore a new set of Austrian reference equations for static lung volumes was developed, that can be applied to both children and adults (6–80 years of age). Supplementary Information.
10 Απρ 2019 · There are four volumes and four capacities recognised in respiratory physiology, where lung volumes are measurable gas-filled spaces in the lung, whereas capacities are combinations of two or more volumes (where the definition of capacity is the measure of the lungs' ability to hold a gas).
