Lung Volumes And Capacities Chart

The below Lung volumes and capacities chart provides the average and normal lung volumes and capacities for men and women. The lung volume is measured using tidal volume (TV), expiratory reserve volume (ERV), and inspiratory reserve volume (IRV) using a spirometer. The lung capacity or vital capacity is the maximum amount of air that can be inhaled or exhaled during a respiratory cycle and is the sum of expiratory reserve volume, tidal volume, and inspiratory reserve volume.

Normal Lung Volumes And Capacities Table

Average Lung Volumes
VolumeValue for Men(L)Value for Women(L)Description
Inspiratory Reserve Volume(IRV)3.11.9Specific amount of additional air that is breathed in with some effort after normal inspiration
Tidal Volume(TV)0.50.5Air Inspired during normal relaxation without any effort
Expiratory Reserve Volume(ERV)1.2 0.7 Specific amount of additional air that is exhaled forcibly after normal expiration.
Residual Volume(RV)1.21.1Amount of air that is remaining in the lungs after full expiration.
Average Lung Capacities
VolumeValue for Men(L)Value for Women(L)DerivationDescription
Vital Capacity(VC)4.83.1IRV +TV + ERVMaximum volume of air that is inhaled or exhaled.
Inspiratory Capacity(IC)3.52.4IRV + TVAmount of Air that is inhaled after a normal expiration
Functional Residual Capacity(FRC)2.31.8ERV + RVVolume of air that is left in the lungs after normal expiration
Total Lung Capacity(TLC)5.84.2IRV + TV + ERV +RVMaximum amount of air that is filled by the lungs

Lung volumes measure the amount of air for a specific function, while lung capacities are the sum of two or more volumes. The inspiratory capacity (IC) is the amount of air that can be inhaled after the end of a normal expiration. Use the above normal lung volumes and capacities table to analyse the volume and capacity of lungs of patients, based on a number of parameters such as IRV, TV, ERV, RV, VC, IC, FRC and TLC.
