16 Ιουλ 2023 · In this article we will look at the lung volumes and capacities, how they are measured and how they are affected by pathology. It is useful to divide the total space within the lungs into volumes and capacities.
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).
The lung capacity calculator determines all the respiratory capacities: Vital capacity (VC); Inspiratory capacity (IC); Functional residual capacity (FRC); Total lung capacity (TLC). based on inspiratory, tidal, expiratory reserve and residual volume that have been measured through spirometry.
Pulmonary Function Tests (PFTs) Calculator. Determines the most commonly tested respiratory parameters and capacities based on easily obtained data and volumes. Purpose. Key Facts. Contents. A Data Required for Pulmonary Function Estimates. Age. Gender. Race. Height. Respiratory rate. B Data Optional (If Known) for Pulmonary Capacities.
Vital Capacity Calculator. Estimates the pulmonary VC based on tidal, inspiratory and expiratory reserve volumes. Purpose. Key Facts. Jump To. Inspiratory reserve volume. Tidal volume. Expiratory reserve volume. Embed Print Share. Other Tools. How to. Variables and formula.
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 Loop
