DL - diffusing capacity of the lung
milliliters of gas the lung can transfer to the blood
ERV - expiratory reserve volume
amount of air you can exhale after a normal exhalation
VT - tidal volume
amount of air you can inhale after a normal exhalation
IRV - inspiratory reserve volume
amount of air you can inhale after a normal inspiration
RV - residual volume
air left in the lungs after a maximum exhalation
TLC - total lung capacity
largest amount of air the lungs can hold
VC - vital capacity
amount of air you can exhale after a maximum inspiration
IC - inspiratory capacity
volume inspired with a normal breath
FRC - functional residual capacity
air left in the lungs after a NORMAL exhalation
MVV - maximal voluntary ventilation
