what is tidal volume? (TV)
what is tidal volume(TV) is the amount of air inhaled or exhaled with each breath under resting conditions.
What is inspiratory reserve volume? (IRV)
inspiratory reserve volume (IRV) is the Amount of air that can be forcefully inhaled after a normal tidal volume inspiration
What is expiratory reserve volume (ERV)?
expiratory reserve volume (ERV) is the amount of air that can be forcefully exhaled after a normal tidal volume expiration
Residual Volume (RV)
Residual Volume (RV) is amount of air remaining in the lungs after a forced expiration
What is total lung capacity (TLC)?
Maxiumum volume of air that lungs can contain. (TLC = IRV + Vt + ERV + RV)
What is vital capacity? (VC)
Maximum volume of air that can be expired after maximum inspiration effort (VC = IRV + TV + ERV)
What is inspiratory capacity? (IC)
Maximum volume of air that can be inspired after normal tidal volume expiration (IC = TV + IRV)
what is functional residual capacity? (FRC)
Volume of air remaining in lungs at end of normal exhalation (FRC = ERV + RV)
