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.
Total Lung Capacity (TLC) It is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. The normal value is about 6,000mL (4‐6 L). TLC is calculated by summation of the four primary lung volumes (TV, IRV, ERV, RV).
Lung volumes refer to the volume of air in the lungs, measured at various phases of the respiratory cycle. Major lung volumes include the tidal volume, inspiratory reserve volume , expiratory reserve volume , and the residual volume .
Define, identify, and determine values for the pulmonary volumes (inspiratory reserve volume [IRV], tidal volume [TV], expiratory reserve volume [ERV], and residual volume [RV]) and the pulmonary capacities (inspiratory capacity [IC], functional residual capacity [FRC], vital capacity [VC], and total lung capacity [TLC]).
24 Ιουλ 2023 · Illustrated in Figure 1, Panel A, the lung capacities can be further divided into the following lung volumes: tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and the residual volume (RV).
The reported spirometric values are generally obtained from a forced maximal expiratory vital capacity (FEVC) maneuver, which is measured when a patient forcefully expels air after a maximum ...
