Tidal Volume
amount of air that moves in then out during a single cycle (~500mL at rest)
Inspiratory Reserve Volume
additional air beyond resting tidal volume with forced maximum inspiration (~3,000mL); complimental air
Expiratory Reserve Volume
additional air beyond resting tidal volume with forced maximum expiration (~1,100mL); supplemental air
Residual Volume
the air remaining in the lungs after the most forceful expiration (~1,200 mL)
Vital Capacity
the max. Volume of air a person can exhale after taking the deepest breath
Insp.Res.Vol. + Tidal Vol. + Exp. Res. Vol = ~4,600 mL
Inspiratory Capacity
the max. Volume of air a person can inhale after resting expiration
Tidal Vol. + Insp. Res. Vol. = ~3,500 mL
Functional Residual Capacity
this is the volume of air left in the lungs following resting expiration
Exp. Res. Vol. + Residual Vol. = ~2,300 mL
Total Lung capacity
Vital Cap. + Residual Vol. = ~5,800 mL
