Lung Volumes and Capacities on a Spirometry Trace Flashcards
What are the 5 volumes on the spirometry trace?
Tidal volumes Inspiratory reserve volume Expiratory reserve volume Residual volume Minimal volume
What are the 4 capacities on a spirometry trace?
Total lung capacity
Vital capacity
Inspiratory capacity
Functional residual capacity
What is the the tidal volume?
the volume of air that you can breath in and out normally in a quiet breath
What is the inspiratory reserve volume?
The total volume of extra air that you can breathe in after breathing in quietly
What is the expiratory reserve volume?
The total volume of extra air that you can breathe out after breathing out quietly
What is the residual volume?
The volume of air left in your lungs after you breath out the most you can
What is the minimal volume?
The volume of air left in your lungs after your lungs collapse
What is the vital capacity?
The total volume of air that you can shift in and out of your lungs (does not include the residual or minimal volumes)
How can you calculate vital capacity?
inspiratory reserve volume + expiratory reserve volume + tidal volume
What is the total lung capacity?
the total volume of air in your lungs when you breathe in to the max (includes the residual and minimal volumes)
How do you calculate the total lung capacity?
minimal volume, residual volume, expiratory reserve volume, tidal volume, inspiratory reserve volume
What is inspiratory capacity?
the total amount of air that you can take into your lungs from rest (quiet breath out)
How do you calculate the inspiratory capacity?
the tidal volume + inspiratory reserve volume
What is the functional residual capacity?
the volume remaining in the lungs after normal exhalation (quiet breath out)
How do you calculate the functional residual capacity?
expiratory reserve volume + residual volume
