Expiratory Reserve Volume (ERV) - The maximum volume of air exhaled from end expiration.
Inspiratory Reserve Volume (IRV) - Maximum volume of air inhaled from end inspiration
Residual Volume (RV) - The volume of air remaining in lungs after maximum exhalation.
Tidal Volume (VT or TV) - Volume of air inhaled or exhaled during each respiratory cycle
Functional Residual capacity (FRC) - Volume of air in the lungs at rest end expiration
Inspiratory Capacity (IC) - Maximum volume of air that can be inhaled from the resting expiratory level
Total Lung Capacity (TLC) - Volume of air in the lungs at maximum inflation
What is the formula for Total Lung Capacity - RV (residual vol.) + VC (volume capacity)
Vital Capacity (VC) - The maximum volume of air exhaled on complete exhaustion after full inspiration.
Forced Vital Capacity (FVC) - Total of air expelled as rapidly as possible (measurement over time)
1st second Forced Expiratory Volume (FEV1) - The volume of air expelled in the first second of FVC (most
reproducible and reliable)
FEV1/FVC ratio - Percentage of maximum inspiration expired in 1 second
How do you determine reversibility - Performing a pre and post bronchodilator spirometry test is
conducted
