Mod2Q14 Flashcards
quiet tidal volume
volume of air exchanged in one cycle of quiet breathing
tidal volume with activity
inspiratory reserve volume (IRV)
air that can be inhaled following one passive inspiration
expiratory reserve volume (ERV)
amount that can be exhaled after one passive exhalation
residual volume (RV)
volume of air remaining in lungs after a maximal exhalation
dead space air
air in respiratory passageways not involved in gas exchange
vital capacity (VC)
volume of air that can be exhaled following a maximal inhalation (VC=IRV+TV+ERV)
functional residual capacity (FRC)
volume of air in the body at the end of passive exhalation (FRC=ERV+RV)
total lung capacity (TLC)
total of inspiratory reserve volume, tidal volume, expiratory reserve volume, and residual volume (TLC=IC+FRC)
inspiratory capacity (IC)
maximum inspiratory volume after tidal expiration (IC=TV+IRV)
