Lung Volumes Ch12 Flashcards
The volume of air inhaled each minute
Minute volume reapiration
The volume of a single inhalation during normal, quiet breathing
Tidal volume
3100ml of air inhaled when taking a very deep breath.
Inspiratory reserve volume
1200ml of air which can be forcibly exhaled in addition to the 500ml of air in the tidal volume
Expiratory reserve volume
1200ml of air remaining in the lungs after expiratory reserve volume has been exhaled
Residual volume
Total volume of air that can be inhaled after the exhalation of the tidal volume.
On avg it is about 3600ml and the sum of the tidal volume and inspiratory reserve volume
Inspiratory capacity
Maximum amount of air that can be exhaled after a deep inhalation.
On avg about 4800ml and is the sum of inspiratory reserve volume, tidal volume and the expiratory reserve volumes
Vital capacity
Total volume of air that can be inhaled.
On avg total volume is about 6000ml
Total lung volume
Three normal breaths into spirometer
Tidal volume
Count the number of times you breath for 3 minutes
Minute respiratory volume
Breath normal for a minute
After normal exhalation
Use abdominal muscles to forcibly exhale all remaining air
Repeat 2 more times
Expiratory reserve volume
Take 3 very deep breaths forcibly inhaling and exhaling take another (4th) and exhale forcibly but slowly into spirometer
Vital capacity
Breath normally for about 2 minutes inhale deeply and exhale normally into spirometer
Inspiratory capacity
Subtract tidal volume from inspiratory capacity
Inspiratory reserve volume
