Compliance, FRC, and Respiratory Volumes Flashcards
How does compliance change as you breath
low compliance at beginning and end of breath
High compliance through middle of breath
What is total compliance a combination of
Chest + lung compliance
What is functional residual capacity
Air in lungs at rest
What happens to FRC when lung compliance is decreased
At the same volume, pressure is increased
What happens when compliance is increased
At the same volume, pressure is decreased
Total lung capacity
All of the air in lungs
Tidal volume
normal breath
Inspiratory capacity
from resting state to max lung can hold
Functional residual capacity
empty lung to resting state
vital capacity
All the air you can breath out (not including residual vol) to the max you can lung can hold
Residual volume
what’s left in your lungs after you breath as much out as possible
Expiratory reserve volume
Resiual volume to resting
What happens during exercise
increase tidal volume
