Quizplus · Accepted Answer

A restrictive pattern is characterized by a reduction in lung volumes, including total lung capacity (TLC) and vital capacity (VC), with a normal residual volume to total lung capacity ratio (RV/TLC). This indicates that while the lung's overall size is reduced, the proportion of air remaining in the lungs after a full exhalation compared to the total lung capacity remains within normal limits.
