A7- Lung Capacity Flashcards
total lung capacity
the maximum volume
of air that can be inhaled during a single
breath
tidal volume
the volume of air inhaled
or exhaled during a normal, involuntary
breath
inspiratory reserve volume
the volume
of air that can be forcibly inhaled after a
normal inhalation
expiratory reserve volume
the volume of air that can be forcibly exhaled after a
normal exhalation
residual volume
the volume of air
remaining in the lungs after a forced
exhalation
vital capacity
the maximum amount of
air that can be inhaled or exhaled
The volume of air in the lungs changes depending on many factors:
Physical Activity
Depth of breath
Sex
Body Type
Lifestyle
Total lung capacity can also be considered:
Inspiratory reserve Volume + Tidal Volume + Expiratory reserve volume + Residual volume
OR
Vital Capacity + Residual Volume
How much L of O2 in average adult during tidal breathing
This is approximately 0.5L in the average adult
VO2 MAX
The maximum rate at which O2 can be used in an indivdual, measured in ML per Kg per min
VO2
An esitmated or measured value representing the rate at which O2 is ued in the body, measure in mL perk Kg per minute
