10% of total lung volume
Volume of air during quite inspiration/expiration - 3IRVInspiratory reserve volume
50% of total lung volume
Maximum volume of air during inspiration after tidal volume - 4ERVExpiratory reserve volume

Maximum volume of air during expiration after tidal volume - 5RVReserve volume
25% of total lung volume
Gas remaining in lungs after a max expiration - 6VCVital capacity
75% of total lung volume
Changes in volume between max inspiration/expiration
VC = IRV+TV+ERV - 7FRCFunctional residual capacity
40% of total lung volume
Volume of air in lungs after a normal exhalation
