Tidal Volume (TV)

the amount of air you move into or out of your lungs during a single respiratory cycle under resting conditions

Expiratory Reserve Volume (ERV)

the amount of air that your can voluntarily expel after you have completed a normal, quiet respiratory cycle

Inspiratory Reserve Volume (IRV)

the amount of air that you can breathe in over and above the tidal volume

Inspiratory Capacity (IC)

the amount of air that you can draw into your lungs after you have completed a quiet respiratory cycle

Vital Capacity (VC)

the maximum amount of air that you can move into or out of your lungs in a single respiratory cycle

Residual Volume (RV)

the amount of air that remains in your lungs even after a maximal inhalation

Total Lung Capacity (TLC)

the total volume of your lungs

anatomic dead space

the volume of air filling the parts of the respiratory tract where gas exchange does not occur (150mL)

TV+ERV equals

expiratory capacity

TV+IRV equals

inspiratory capacity

IRV+TV+ERV equals

vital capacity

VC+RV equals

total lung capacity

500mL in, 500mL out equals

tidal volume

these muscles are used during normal inspiration

external intercostals
diaphragm

muscles used during forced exhalation

internal intercostals
external and internal obliques
rectus abdominus

muscles used during forced inhalation

sternocleidomastoid
pectoralis minor

TLC calculation

TLC = FRC + IC

\
(Total lung capacity = functional residual volume + inspiration capacity )

(Inspired volume) 6000-3000(tidal volume) = 3000
