Could anyone kindly help me memorizing the relationships between all these lung volumes?
FRC+IC=TLC
FRC=ERV+RV
IC=IRV+VT
VC=IRV+VT+ERV
FRC Functional residul capacity
IC Insp capacity
TLC Total lung capacity
FRC Functional residual capacity
ERV Exp reserve vol
RV Residual vol
IRV Insp reserve vol
VT Tidal vol
VC Vital capacity
FRC+IC=TLC
FRC=ERV+RV
IC=IRV+VT
VC=IRV+VT+ERV
FRC Functional residul capacity
IC Insp capacity
TLC Total lung capacity
FRC Functional residual capacity
ERV Exp reserve vol
RV Residual vol
IRV Insp reserve vol
VT Tidal vol
VC Vital capacity
