NR 601 PFT Quiz
Expiratory Reserve Volume (ERV) - answer The maximum volume of air exhaled from
end expiration.
Inspiratory Reserve Volume (IRV) - answer Maximum volume of air inhaled from end
inspiration
Residual Volume (RV) - answer The volume of air remaining in lungs after maximum
exhalation.
Tidal Volume (VT or TV) - answer Volume of air inhaled or exhaled during each
respiratory cycle
Functional Residual capacity (FRC) - answer Volume of air in the lungs at rest end
expiration
Inspiratory Capacity (IC) - answer Maximum volume of air that can be inhaled from the
resting expiratory level
Total Lung Capacity (TLC) - answer Volume of air in the lungs at maximum inflation
What is the formula for Total Lung Capacity - answerRV (residual vol.) + VC (volume
capacity)
Vital Capacity (VC) - answerThe maximum volume of air exhaled on complete
exhaustion after full inspiration.
Forced Vital Capacity (FVC) - answerTotal of air expelled as rapidly as possible
(measurement over time)
1st second Forced Expiratory Volume (FEV1) - answerThe volume of air expelled in the
first second of FVC (most reproducible and reliable)
FEV1/FVC ratio - answerPercentage of maximum inspiration expired in 1 second
How do you determine reversibility - answerPerforming a pre and post bronchodilator
spirometry test is conducted
What is a significant response in adults considered - answerGreater than or equal to
12% improvement in FEV1(or FVC)
significant response = indicative of asthma
