Topic 7.3 Flashcards
1
Q
What does volume of lungs depend on?
A
- Transpulmonary pressure
2
Q
What volume of lungs measured with?
A
Spirometer
3
Q
Define tidal volume
A
- Difference between lung volume in normal inspiration + normal expiration
4
Q
Define inspiratory reserve volume
A
Additional air that you can fill in your lungs after normal inspiration
5
Q
Define expiratory reserve volume
A
- Additional air expelled from lungs after normal expiration
6
Q
Define functional residual capacity
A
- Air remaining in lungs after normal expiration
7
Q
Define vital capacity
A
- Difference in lung volume after deep inspiration + deep expiration
8
Q
Define airway resistance
A
- Ratio of pressure difference: volume rate of airflow
- Units = Pa/L
- Depends on dimension of tube + velocity of gas
