Normal Lung Volumes

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.
