Part Description

LP76186-3   Capacity.total
Total lung capacity (TLC) is the volume of air in the lungs at maximum inflation. TLC can be derived as the sum of the vital capacity (VC), the largest volume a patient can exhale after a full inhalation, and residual volume (RV), the volume of air remaining in the lungs after maximum exhalation). Functional residual capacity (FRC) is the volume of air remaining in the lungs after normal exhalation. Restrictive lung diseases, such as pulmonary fibrosis and neonatal respiratory distress syndrome, generally lead to a decrease in various lung volumes, while obstructive lung diseases, such as asthma, are associated with preserved total volumes. However, obstructive disease may be associated with high RV values, which may also be expressed as RV/TLC, which represents RV as a percentage of TLC. Source: Regenstrief LOINC
