Pulmonary Volume and Pulmonary Capacities

Tidal Volume

• Amount of air inhaled or exhaled during exercise
• Amount of air inhaled or exhaled during sleep
• Amount of air inhaled or exhaled during forceful breathing
• Amount of air inhaled or exhaled during normal breathing

Expiratory reserve volume

• The amount of air inhaled during a normal breath
• The amount of air remaining in the lungs after a forced exhalation
• The maximum amount of air that can be inhaled after a normal tidal volume inhalation
• Exhale more than normal

Residual volume

• Air that remains in lungs after full exhale

• Amount of air in lungs after inhale

• Exhale more than normal

• Minimum inhale amount

Inspiratory reserve volume

• Inhale more than normal

• Inhale less than normal

• The amount of air that can be exhaled forcefully after a normal exhalation
• The amount of air that remains in the lungs after a maximum exhalation

Inspiratory capacity

• Taking a deep breath

• Volume of air that can be forcefully exhaled after a normal tidal volume expiration
• Taking shallow breaths

• Volume of air that can be inhaled after a forced expiration

Vital capacity

• Maximum inhale followed by maximum exhale

• The amount of air a person can exhale after a normal inhalation.
• The amount of air a person can inhale after a normal exhalation.
• The amount of air a person can inhale after a maximum exhalation.

Functional residual capacity

• The volume of air that remains in the lungs after a normal inhalation.
• The volume of air that is exhaled during a normal breath.
• The volume of air that is inhaled during a normal breath.
• The volume of air that remains in the lungs after a normal exhalation.

Total lung capacity

• The amount of air lungs can hold at rest
• The amount of air lungs can hold during exercise
• The amount of air lungs can hold after exhaling
• Total volume of air in the lungs
