Respiratory Air Volumes

the amount of air in the air passages after a maximum forced inhalation
- Total lung capacity
- TLC=TV+IRV+ERV+RV
the amount of air one can forcibly inhale after a normal inhalation

Inspiratory reserve volume (IRV)
the amount of air in the air passages after they have been open

Minimal volume (200 cc/minute; part of Residual volume)
the amount of air one can forcibly exhale after a normal exhalation

Expiratory reserve volume (ERV)
the amount of air one breathes in or out per minute
- Minute respiratory volume (6000 cc/minute)
- TV x Breaths/min
the amount of air in the air passages after a normal exhalation
- Functional residual capacity (FRC)
- FRC=ERV+RV
the amount of air one breathes in or out per breath

Tidal volume (TV)
the amount of air one can inhale after a normal exhalation
- Inspiratory capacity (IC)
- IC=TV+IRV
the amount of air one can exhale after a maximum forced inhalation
- Vital capacity (VC)
- VC=TV+IRV+ERV
the amount of air in the air passages after a maximum forced exhalation

Residual volume (RV)
Normal Breathing Rate=__?__ breaths/minute
